Jewelry Care Questions

How to properly care for our gold jewelry?

When using gold jewelry, it is advisable to pay attention to taking off our ring, bracelet for the night, bathing or washing dishes. The color of gold jewelry is determined by alloying materials. There are alloying metals that can cause an allergic reaction in some people, so it is recommended to choose jewelry made of quality gold.

Gold jewelry does not oxidize, but it can easily get dirty and stain. Creams, powders, soap, and even the natural fat content of the skin can grasp on the surface of the jewelry, which can make it dirty. If you clean the gold jewelry correctly and carefully, it will retain its glow and last a lifetime. In most cases, clean water and a mild detergent are enough for cleaning, and with a soft brush you can easily clean the finely crafted parts and stones. After cleaning, of course, you need to dry the gold jewelry with a clean cloth or kerchief. A jewel-cleaning rag is an effective and inexpensive solution for cleaning gold jewelry. These are usually made of cotton and help to remove dirt from the jewelry and improve the jewelry as if it were new. Various cleaning liquids can be used, depending on whether it's gold, silver or precious jewelry. Choose from us to clean your jewelry from the high quality Hagerty product line so you can clean your jewelry professionally at home.

The use of gold purifying liquid:

  • Pour a little gold cleaning liquid into a bowl
  • Suck up some gold cleaning liquid with a soft, dust-free cotton cloth
  • Pull the rag once or twice on the jewel surface with a careful one-way motion
  • Do not scrub or rub the surface of the jewelry, as it can easily be scratched. Strive to carry out the cleaning with fewer movements
  • Finally, rinse the jewelry under running water!

How to properly care for your silver jewelry?

The aim of proper care is to ensure that our jewellery retains its original shine for as long as possible. Silver is practically not oxidized either at low or high temperatures. The black-gray discoloration seen on silver objects is not an oxide, but a compound of silver with sulfur. The air of cities contains more and more sulfur compounds, which, under the influence of moisture, forms silver sulphide (Ag2S). Therefore, the surface of the object is first brown and later a soot black coating is formed.

How to remove blackening from silver jewelry

To maintain the new state of silver jewellery for a long time and to prevent the formation of a thicker silver sulphide layer, it should be regularly wiped with a clean cloth made of soft, scratch-free material. Soapy water also helps to preserve the beauty of jewelry, but do not forget that when wiping dry, do not use paper towels or paper handkerchiefs, only soft cloth. If simple cleaning done at home, does not work, then the black silver-sulfide layer deposited on the jewelry can also be removed with the commercially available silver cleaning liquid. The silver-cleaning liquid is used only for cleaning non-antique jewelry, objects without stones or pearls!

If the above does not work, then contact a jeweler/goldsmith who polishes our jewelry.

The use of silver cleaning liquid:

  • Pour out into a bowl a little silver-cleaning liquid,
  • Suck up some silver-cleaning liquid with a soft, dust-free cotton cloth,
  • With a careful one-way motion, pull the rag once or twice on the surface of the jewel,
  • Do not scrub or rub the surface of the jewelry, as it can easily be scratched, strive to do the cleaning with as few movements as possible,
  • Finally, rinse the jewelry under running water!

How to properly care for jewellery decorated with diamonds or gemstones?

  • Diamond and most pure precious stones (e.g. ruby, sapphires and emeralds) are easy to clean because of their hardness. All you need to do is carefully remove dirt from the surface of the stones, if this is possible, so that the precious stones can regain their original shine again.
  • If you want to keep your precious stones shine as long as possible, despite some home-made jewelry cleaning advice, do not put your jewellery in chlorine, salt water or soda. Many household cleaners are based on chlorine-containing bleaching, which can discolour or dissolve precious stones.
  • Do not use ultrasonic cleaners, salmiac liquor or any other chemicals to clean precious stones; especially in turquoise, malachite, onyx, lapis lazuli and opal, as this can easily cause discoloration of stones.
  • If the jewel contains precious stones or pearls, do not put them in water, as the setting may become loose. Do not use bath cleaners or abrasive cleaners for your precious stones.

How to store our jewelry correctly?

When we are not wearing our jewellery, we should store it in an airtight, dry place. It is best to keep it in a lined box or in a jewelry box that has compartments that are all lined separately, because it is also important to make sure that the jewellery does not come into contact with each other in the box, as they can scratch each other. We also need to check the settings of the stones regularly, so as not to notice that you do not have the beautiful gleaming stone from the gold jewelry. Choose from us to store your jewelry from the high quality STACKERS range to store your jewelry properly for many years.

What should I pay attention to when using jewelry, what are the rules for the correct use of jewelry?

  • Do not wear jewellery in activities where it can be damaged, stuck in something, pressed, rubbed, for example, household chores, playing sports, washing dishes, etc.
  • Be careful not to wear jewelry while dressing, as it can get stuck in the dress, tear, in stony jewelry, the stone socket may open, resulting in the fall of stones.
  • Do not lubricate or spray perfume, cream (perfume, deodorant, hair spray, suncream, lotion, etc.) directly on the jewelry, as this may cause matting or milling.
  • Do not sleep in jewelry, because during sleep it can deform, press or tear.
  • Be careful not to drop or hit the jewellery, as it may result in injury or loss of the gem on gem jewellery.
  • Keep jewelry away from medicinal waters, beaches, swimming pools, as they can cause strong discoloration and loss of jewelery shine
  • Do not wear any jewelry during bathing or showering.
  • Protect our jewelry from bright light and heat, because it can cause discoloration of jewellery and stones.
  • Chemicals can damage the jewellery, cause matting or milling on its surface, so always remove the jewelry when in contact with household chemicals and agents.

How to easily determine the correct ring size?

Measure the diameter of a convenient ring with a ruler and find out the size of the diameter from the table below.

Measure the circumference of your finger by inches, then find out the size of your fingernail from the size chart below.

It is important that you can buy a ring one or two sizes different compared to the established size, since the different sizes are very small, only a few tenth of a millimeter difference, and the thickness of the finger can vary, i.e. depending on the temperature. For a thinner, filigree ring, it is better to choose a smaller size, for example, in case of a wider seal ring it is worth choosing a slightly larger size.


What does the hallmark on the jewelry mean?

The Hungarian hallmark has been ordered by law since 1867, which confirms the content of gold, silver or platinum in the alloy. The hallmark is a guarantee that the precious metal object or jewelry you want to buy is really made of gold or silver of the specified fineness. Since the hallmarks change from time to time, it is also possible to determine when an object was made in magnitude.

The valid Hungarian hallmark is intended to prove what precious metal the jewellery is made of and its fineness. The gold markings currently valid are 916 (22 carats), 750 (18 carats), 585 (14 carats), 375 (9 carats), where the numbers refer to the fineness of gold. So, to determine how many thousand of the alloy has a solid gold duration:

  • 22 carats = 916 millisimals = 91.6% pure gold content
  • 18 carats = 750 millisimals = 75,0% pure gold content
  • 14 carats = 585 thousand = 58.5% pure gold content
  • 9 carats = 375 millisimals = 37.5% pure gold content

The silver metal markings are: 925, 900, 835, 800. Here the figures denote the fineness of silver. 

From the hallmark, the following can be determined:

  • the country in which it was marked
  • whether produced domestically or originated from abroad
  • fineness of the precious metal alloy and
  • approximate age of the object.

What should I pay attention to when buying a diamond, what determines the value of a diamond?

The value of a diamond can be determined on the basis of the so-called 4C. This 4C stands for the English abbreviation for cut, color, clearness and carat.


Is there a replacement option if you do not like the watch or jewelry taken as a gift?

In the case of new jewelry or new watch, yes, within 5 days of purchase, against cerificates. If the new jewellery or the new watch is in perfect condition, it is possible to replace or spend its purchase price.  

How long are there warranties for watchs/jewellery?

In case of buying new jewelry or a new watch, if the selling price is above 10,000.- HUF, the buyer is entitled to a warranty. The warranty period, depending on the selling price of the hour/jewelry:

  • between 10,000 HUF and 100,000 HUF: one year,
  • between 100,000 HUF and 250,000 HUF: two years,
  • above 250,000 HUF: three years.

In the case of purchase of used watches and jewellery and other goods, as well as new jewellery or watch, the buyer will be entitled to a guarantee after the warranty period. The guarantee period is 2 (two) years from the date of purchase.

Watch constructions

When buying wristwatches, it is most often the design that decides which model the customer should vote in favor of. However, in addition to the aesthetic appearance, it is worth paying more serious attention to the structure of the wristwatch. Today, in the clockmaking industry, two main structural constructions are used. One is electronic structural technology, the other is traditional, 14th-century mechanical engineering technology. In the case of the first line, in addition to the only analog (show) display dials, in some cases analogue displays with digital display, while one of the features of the latter technology, even in the case of very complicated solutions, is the use of exclusively analog dials. Almost 90 percent of the Swiss watch industry's production is quartz wristwatches. By the way, these are typically analogous pieces. It is interesting that, however, mechanical watches produced as a result of 10 percent capacity of industrial production account for more than 50 percent of Swiss watch exports.

Mechanical structures

Nowadays they are the most fashionable types of structures. This “fashion” is not unfounded, as a more serious mechanical structure can be worth wealth. Mechanical structures are basically hand-wound structures, which means that the energy necessary for walking must be “wound” by pulling out the crown. This operation can become an integral part of our daily program, since it is appropriate to wind a manual structure every day, and in the most optimal case always at the same time. To eliminate this — a tedious, difficult task for some people — automatic devices are designed and constructed, which are wound by themselves during everyday wear. This process is carried out with the help of a rotor, which comes into swing from the movement of the hand and tightens the spring located in the spring housing, which is the “element” of the mechanical clock. Between mechanical clock mechanisms, the manual wound one is less accurate, while the automatic mechanism is more accurate, since it is in a constant drag state. The power reserve for manual wound structures is also less, since the automatic structure is in a state of constant winding, which comes from constant wearing. To the elite group of mechanical structures include chronometers, which are the most accurately working time meters. The gait deviation of the structures is between -4 and +6 seconds per day. Of course, these are not ship chronometers, but wristwatch structures that can be controlled as chronometers. The gait deviation is investigated by an independent Swiss institute, for 15 days and nights, when the structures are subjected to various thermal shocks, and an interesting moment in the study, when the clock mechanisms are placed in different positions (e.g. with the front down). The structures are also usually purchased by the largest Swiss watch manufacturers. However, the whole matter is not so simple, since these structures are already rebuilt into the models of patina manufacturers. A traditional mechanical structure is made up of about 130 small parts. It is important to remember that the more and more complex complications the watchman makes, the more components will be included in the structure. There are three really important elements of mechanical devices: the energy storage unit, the control units and the parts responsible for the display.

The mechanical clock mechanism is made up of the following parts:

  • Spring housing, this performs energy storage
  • Wheel system that transmits mechanical force
  • Barrier structure, which is responsible for the precise flight
  • Wobblers and main springs which determine the frequency of operation of the structure
  • Crown, this is used to set the exact time. In the case of manual winding models, it helps to tighten the spring in the spring housing
  • Swing weight (rotor), in the case of automatic watches this tightens the spring of the spring
  • Dial with only analog time display

Quartz constructions

These aggregates are the inventions of the 1980s, the “driving force” of which is the vibration of quartz crystals. The clockwork that works most accurately. Its disadvantage is that it works for a limited time, exactly until the battery is exhausted. This can last up to 6 years for better batteries. The soul of the quartz watch with analog display is an integrated circuit with a large number of electronic components on the base plate of just a few square millimeters. The power supply of the structure is ensured by a small battery that operates for many years. Another important part of the quartz structure is the unit that regulates the vibration of quartz crystals. This quartz vibration mechanism allows a very high frequency vibration (32kHz), resulting in a very accurate timing device. The biggest advantage of quartz structures is that they produce only 1 minute of walking in a year, which means less than one second a day.

There are two main categories of quartz watches. The first models, already presented above, with an analog display, are built from the following components:

  • The energy supply component
  • Integrated circuit controlling quartz crystals and rotor
  • Quartz vibration maker, it is responsible for precise timing
  • Frequency control unit
  • Rotor, which turns electronic pulses into mechanical energy
  • Wheel system that moves the clock, minute and second indicators
  • Analog dial

Another subspecies of quartz watches is a watch made with a digital display. The essence of this is to completely ignore the wheel system, since its liquid crystal (LCD) display can control the transparency during the existence of an electric field. With such a “dial” in Switzerland, watches are no longer very produced, the collection of factories consists of combined variants of the two above types of quartz structures.

Autoquartz constructions

Many people desire that the structure of their watches does not require - often reasonably depressing - excessive attention, do not have to worry that after a weekend or a longer rest, the structure of the wristwatch placed in a state of rest for 48 hours stops, and, of course, when most in a hurry - have to adjust it again. Many people expect the structure of their watches to have no significant gait deviations after long months and to show the time exactly for at least minutes. Some desire that, in addition to all of the above, the structure does not need that button cell, which always runs out at the most inopportune moment. In addition, environmental protection has now become an important factor. Autoquartz devices have been developed for these watches, two types of which are kinetic energy and light energy.

The essence of the operation of the kinetic energy mechanism is that on the principle of automatic structures a rotor - rotating from the movement of the hand - rotates a magnetic wheel in front of the coil through the transmissions, in which current is induced. The generated current is stored in a capacitor, which provides the energy necessary for operation, even without movement for up to 4 years. It does all this without the use of elements, drawing energy from the movement of the hand.

The structure with light energy can utilize light of any type - natural and artificial. The solar cell located under the dial or around the dial converts the light energy into the electrical energy necessary for the operation of the clock and then stores it in the capacitor, like autoquartz structures with kinetic energy. These watches are fully charged for 4-12 months, some models can work up to 5 years without obtaining additional light energy.

Advantages of autoquartz structures are:

  • environmentally friendly technology
  • quartz watch accuracy (±15-20 sec/month)
  • long power reserve
  • low maintenance and service requirements

Watch usage advice

Annotations relating to watertightness:

  • “Water resistant” or “3 ATM” or “3 BAR” or “30 M”:
    It can be read on the back of the watch. Meaning: the watch is dropproof. In the rain, when washing hands, the clock is not damaged, but it can not be used for swimming or showering! Water is wiped with a soft cloth. Never use the crown and push-buttons of the clock when the clock is wet!
  • '5 ATM' or '5 BAR' or '50 M':
    A watch with such an inscription is suitable for swimming, but not for diving and other water sports! Never use the crown and push-buttons of the clock when the clock is wet!
  • '10 ATM' or '10 BAR' or '100 M':
    A watch with such an inscription is suitable for swimming, water sports and surface diving in not very deep water. Wash the watch with fresh water after use in salted water and wipe dry! Never use the crown and push-buttons of the clock when the clock is wet!
  • We recommend using a special diving watch for diving!


If there is no waterproof marking on the watch face or back panel, the watch should be protected from wet environments as this may cause the device to malfunction (e.g. washing hands, washing dishes, cooking, washing, sweating, etc.).
Also, when wearing waterproof models, avoid using thermal water, hot water, soap or shower gel, as this can lead to immediate damage to the seals.
Before using it in water, always make sure that the crown and push-buttons are in the default position and that the glass or watch case is not damaged, because only in this case the watch is waterproof!
In order to protect waterproof, have your watch inspected at least every 2 years.
In case of wear other than average use (excessive sweating, heavily polluted environment, etc.), check the gaskets more often.
With models with leather or fabric belts, bathing and swimming are not recommended, as this will lead to untimely, rapid destruction of the belt!
Due to incorrect buckle size or excessive tightening of the belt, the adjusting crown can be pressed against the back of the hand, causing leaking, jamming, tearing, breaking, or stopping the watch!

Advice for use:

Protect your watch:

  • from impact, impact, sharp objects, abrasion,
  • direct, strong magnetic field (TV, speaker, microwave),
  • from an exceptionally high temperature (above 60 oC) (never take the watch to the sauna!), -10 Celsius, or prolonged cold temperatures below -10 Celsius,
  • from chemicals (cosmetics, gasoline, soap, mercury, medicinal water, excessive sweating, etc.), because the case and buckle can be damaged, discolored, the seal can be damaged!

After 2-3 years, the seals will grow old even if you do not use your watch. Check the condition of the seals in a professional workshop for trouble-free use.
Jewelry watches are recommended only for casual wear because of their nature! Some models acquire a special decorative coating, which can wear off during daily use.

The exact operation of the clock is guaranteed between 5-35 Celsius.

Carry out cleaning of watches and carbuckles with a soft, dry cloth, possibly slightly moistened.
If you notice any abnormalities, contact a qualified workshop immediately.
