Product care


Jewelry & timepieces pass on from generation to generation, reminding us of exciting moments and carry a sentimental value.  Like every product and a material, maintenance is required due to the natural wear and tear that occurs over time.  We collected important points about the nature of the materials, so you can take care to maintain and have the longevity pleasure of wearing the jewelry or timepiece. 


Over time, dust, soap, lotion, etc., accumulative daily wear & tear factors affecting the brilliance of gold and stones.  Gold, platinum and silver can be scratched, worn and abraded and even change color.  These natural raw materials breathe and are not static and therefore react in combination with other substances.  Stone settings made of gold or platinum also wear out. Small hits, pressure on the stone, catching with an object, ect. All these can move the stone and / or break a prong and even cause the loss of a stone. 

Jewels which are crafted with a flexible movement, a friction is created between the links, thus creating wear and tear, also with flexibility there is a likelihood that gold will stretch (eg tennis bracelets / flexible rings) 

Clasps of Necklaces, bracelets and earrings backs (like Alfa) are patents with a spring mechanism.  The spring mechanism, like in any other product has a reasonable wear out. 

Our suggestions:

  • As part of "Miller" customer service, we offer to bring the Jewel purchased at "Miller", once a year for renewal and examination. When renewing, we clean and polish the jewelry and after our professional jewelers will examine the piece to make sure all the stone settings are stable, in this way if any repair is needed we can alert you ahead.
  • After wearing the jewel preferably put it back in a storage box or pouch, without any contact with other stones or other objects, and in a dry place.
  • Avoid from any contact of the jewel with chemicals eg bleach, chlorine or other detergents that can damage the gold, platinum or silver.
  • Silver jewelry tends to tarnish with time; it is advisable to avoid an extended contact of the jewel with water and to avoid contact with salt water or any other substance that can cause staining or discoloration.  When such an event occurs the jewel can be washed with lukewarm water and dry immediately with a dry cloth.
  • Jewelry & timepieces with gold plating, it is important to know that over time the coating may be reduced, depending on the degree of exposure to humidity, salt water and scrubbing with other objects.
  • Some jewelry integrates leather.  The leather is more sensitive than an alloy and with a natural wear of discoloration; it is advisable to avoid sleep, shower, exposure to high temperatures and humidity.



Gems vary in levels of toughness and durability.  Most gems are set in a way that the stone is exposed to the maximum, so it's important to be aware from hitting the stone or piece on hard objects, doorposts, manner of placing the jewel on the table, ect. These can abrade and chip the stone or the gold prong holding the stone.  Even though diamond is considered to be the most durable precious stone, it may be damaged if hit in a certain angle or with enough force.  There are gems that are more delicate such as emeralds, amethyst, tanzanite, opal, tourmaline, pearl, ect.

Gemstones precautions:

  • It is best not to wear jewelry in a stack to avoid aberration
  • Avoid exposure to extreme changes in temperature.
  • Avoid contact of the stone with chemicals and cosmetic products. For example, it is best to wear perfume before the jewelry is worn.
  • Occasionally it is important to make sure the stones are stable in the setting.   If it seems the stone is loose in its setting, it is recommended to bring it to the workshop as earliest as possible.



As with any electronic / mechanical device, a timepiece should be maintained on a regular basis in order for it to work perfectly.  The maintenance frequency depends on the type of timepiece, climate and caution of the wearer.
