Jewellery Care
  • With the proper care, precious jewellery should last for decades and remain a valuable possession. By taking good care and applying practical advice, you can safeguard your jewellery and ensure it stays with you forever.
  • Protect your jewellery from sharp blows, scratches, chemicals, sunlight and extreme temperatures. Store your jewellery in a soft-lined box or pouch. Try to keep your jewellery pieces apart, so that they don't rub against each other or get tangled up.
  • Wear jewellery for appropriate occasions. Avoid wearing rings when doing household chores or engaging in sporting activities. Stones can be knocked loose and jewellery may come in contact with abrasive elements, which discolour the metal.
  • Don't let your jewellery come into contact with nail polish removers, perfume or hairspray. This may discolour gold or make pearls turn yellow. Put jewellery on only after you have applied cosmetics or sprays.
  • Settings can become clogged with soap and hand cream. Take rings and bracelets off when washing your hands. When using a public lavatory, secure hand rings to your necklace or place them in a pouch inside your handbag or purse.
  • Heat and hot water can loosen jewellery settings in which an adhesive has been used. Pearl rings, earrings and pendants have this type of setting, so take extra care with them.
  • Never go swimming with your jewellery. Chlorine in swimming pools can cause extensive damage.
  • Clean your jewellery periodically. Use a soft toothbrush and warm soapy water to get into any difficult nooks and crannies. You can also purchase a professional jewellery cleaning product. Make sure to read the manufacturer's instructions.

Gold, Platinum and Silver Care Tips

  • Like all jewellery, gold should be periodically cleaned and checked for wear and breakage. You can clean it with warm, soapy water or let your jeweller repolish it. 
  • Platinum jewellery should be cleaned using a prepackaged jewellery cleaner, or have it cleaned professionally by your jeweller. As with all precious jewellery, store pieces separately to avoid scratching.
  • Sterling silver will tarnish with time and wear. Polish it by rubbing or buffing with a soft cotton cloth or sunshine cloth. If you store your silver in a plastic bag with an interlocking seal, it will be less prone to becoming tarnished. Some silver jewellery pieces are coated with rhodium, which is designed to make it tarnish resistant. Clean rhodium-coated sterling silver with a soft polishing rag or a fine silver cleaner. Do not use silver dip as it may cause potential damage to the rhodium finish or any inlaid gemstone.

Diamond Care Tips

  • Many people think diamonds are indestructible, but special care is still required to protect them from loss or damage. 
  • While they are resistant to heat, scratches and can be cut only by another diamond, strong impact against a diamond's girdle can cause chipping or abrasion. 
  • Make sure your diamonds are safely secured in their settings, especially those with claw-set rings. Do not use soft metals like 24k gold. Jewellery with loose stones should be repaired by a jeweller before being worn again. 
  • Diamonds scratch other jewellery, so keep them wrapped or store them separately, especially from other diamond jewellery.
  • Diamonds can be covered by a greasy film caused by dead skin, dust and grit. There are several ways to clean your diamonds, depending on the metal mount it is set in.
  • Most diamonds set in gold or platinum can be cleaned in a detergent bath consisting of warm water and a mild household detergent. Gently scrub with a soft, non-metallic brush and rinse in warm water. Wipe with a soft, lint-free cloth. Avoid using cleaning agents that contain abrasives, such as toothpaste.
  • Diamonds set in gold alloys with high karat (18k and above) will not be damaged by household chemicals. However, lower karat alloys (14k and below) are subject to stress corrosion by chlorine-based bleach and other cleaning chemicals. Avoid contact between these chemicals and your jewellery.
  • Ultrasonic cleaners perform the job with liquids, usually a mixture of ammonia and detergent. It is best to have a professional jeweller clean your diamonds, but for a quick homemade remedy, you can prepare a solution consisting of one-part ammonia to six-parts water.

Gemstone Care Tips

  • To minimise jewellery rubbing together, use a jewellery box with different compartments that are well-padded. Or, better still, keep them in their individual boxes. 
  • Use a proper, manufactured solution to clean gemstones. Such products can be bought from most jewellery outlets. Hard stones such as diamonds, garnets, sapphires, rubies and amethysts can be dipped in a bowl of warm, soapy water and brushed with an old, soft toothbrush. Be careful not to poke under the gemstones as this may dislodge them from their setting. Amber can be cleaned in the same manner, as long as it is dried straight away. Some stones can be quite porous (such as pearls, jade, jet, lapis, emeralds, opal and turquoise), so they should not be dipped in water. Dipping can strip some of these stones of their oils.
  • Some stones are also damaged by sunlight. These include:

    Amethyst: becomes paler.
    Ametrine: may change colour.
    Aquamarine: becomes paler.
    Aventurine: translucent types often lose colour.
    Beryl: brown or orange types may become pale pink.
    Citrine: may change colour.
    Kunzite: becomes pale or loses colour.
    Rose Quartz: becomes paler.
    Smoky Quartz: becomes paler.
     
  • Gemstones that are mounted on rings may become loose or rattle. If this occurs, visit your local jeweller before it's too late. It is much cheaper to have the prongs repaired than to replace a gemstone. Prongs are easily 're-tipped' by most jewellers in order to keep the stone secure.

Pearl Care Tips

  • Most pearls worn today are cultured, but though cultured pearls have thicker coatings, they are more fragile than other gemstones.
  • Pearls consist of an organic material called conchiolin, which is susceptible to acidic substances such as sweat, vinegar, fruit juices and detergents. These acids cause discolouration, loss of lustre, and dissolution of the aragonite crystals that make up the layers of nacre. Clean your pearls immediately to counter these damaging effects. Use a soft, dry, lint-free cloth such as silicon cloth or chamois to wipe your pearls. You can dampen the cloth with water as long as you allow your pearls to air dry before storing them. Stubborn dirt can be washed away with a mild soap solution (try using Ivory Flakes). Placing a drop of olive oil on the cloth can help maintain lustre. Do not use abrasive cloths, ammonia-based cleaners, harsh detergents, or an ultrasonic cleaner for cleaning your pearls. 
  • Even if pearls are exceptionally cohesive and shockproof, they rank low on the Mohs hardness scale. Avoid permanent scarring caused by contact with sharp objects or rough surfaces.
  • Pearl necklaces or bracelets must be restrung at least once a year. Silk or nylon strings absorb sweat and humidity and will either stretch, loosen or suddenly break. If there is space between the pearls, it is an indication that the string must soon be replaced. When having pearls customised into a necklace or bracelet, request the jeweller to leave a knot between each pearl to prevent them from rubbing against each other. This will also ensure that only one pearl will drop if the string breaks.

Screw-Lock Crown
A crown that can be screwed into the case to make the watch watertight.

Skeleton Case
A transparent front or back that permits one to view the inner workings of the watch.

Solar-Powered
A watch that uses solar energy derived from any light source to power the quartz movement. The batteries are recharged by solar panels on the watch’s face, and a power reserve function allows the watch to run in the dark.

Water Resistant
Ability to resist damage caused by exposure to water.

What is Swiss Made?

If you are new to the world of horology and want a quality timepiece, just look for the words ‘Swiss Made’ stamped on the dial. According to a European law that regulates the use of the name ‘Swiss’ for watches, a Swiss Made timepiece is one that has been assembled, adjusted and subjected to official tests in Switzerland. In addition, at least 50% of the components of the movement should be manufactured in Switzerland.

What does the Swiss Made label mean for you?

The words ‘Swiss Made’ guarantee the highest standards of quality and assurance. It includes the technical quality of watches (accuracy, reliability, water-resistance and shock-resistance), as well as their aesthetic quality (elegance and originality of design). The guarantee covers both traditional manufacturing and new technologies.

What lies behind this reputation?

The fundamental values of the Swiss Made label not only represent high-quality timepieces, but they also maintain their high standards, giving consumers the best of assurance. The Swiss Made name faces strong competition, however, thanks to the unique infrastructure, know-how, and spirit of innovation, it has succeeded in maintaining its leading position.

How is ‘Swiss Made’ defined by law?

A watch is defined as Swiss Made only when it carry the indications ‘Swiss Made’ or ‘Swiss’, or any other expression containing the word ‘Swiss’ or its translation. According to Swiss law, a watch is considered Swiss if:

  • Its movement is Swiss
  • Its movement is cased up in Switzerland
  • The manufacturer carries out the final inspection in Switzerland

A Swiss Watch Movement is considered Swiss, if:

  • It has been assembled in Switzerland
  • It has been inspected by the manufacturer in Switzerland
  • The components of Swiss manufacture account for at least 50 percent of the total value, without taking into account the cost of assembly

Bernhard H. Mayer® watches are manufactured in accordance with Swiss watchmaking traditions and follow the highest standards of product quality and craftsmanship. That means the standard and quality of our watches are more than assured.
