Only the Purest Will Do
Before we consider any gemstone fit for our customers, every piece must pass more than 10 appraisals by our experienced jewellers. The stones are then subjected to state-of-the-art spectroscopic methods including infrared spectroscopy
and UV-Vis spectroscopy for the chemical composition analysis. These most stringent tests ensure that the gemstones you enjoy are truly genuine and free of artificial processing.

Care for Your Fine Jewellery
Fine jewellery is a valuable gift from nature; thus, it requires vigilant care to ensure its timeless quality.

collections that feature a variety of gemstones have been artfully designed with hues, colours and tones that beautifully complement each other – offering you masterpieces that will be cherished for generations
to come.
Colored Gemstone Care
Different types of gemstones have different levels of hardness. Gemstones that are soft and contain more inclusions, such as emeralds, are especially delicate. Please handle them with extra care while wearing and storing.
- Avoid leaving gemstones under direct sunlight or exposing them to high temperature. This may alter the color or brilliance of the gemstones.
- Gemstones can scratch or damage each other. Therefore, avoid stacking gem-set jewellery together to prevent abrasions.
- Soak your gemstones in mild soapy water and brush them lightly with a soft brush. Then pat them dry with a soft, lint-free cloth.
Care for Your Fine Jewellery
-
Fine jewellery is a valuable gift from nature; thus, it requires vigilant care to ensure its timeless quality. Thus, we would like to recommend the following measures on jewellery maintenance:
- Professional cleaning at least once a year is recommended.
- Do not wear jewellery when doing exercise, housework or sleeping. Impact against hard surfaces may damage the setting and cause the gem to fall out, or may deform its shape, especially for jewellery with complicated structures or hollow designs. Stop wearing it if the gem set is found loose.
- Perfumes, cosmetics, household chemicals, detergents and even chlorinated pool water can damage your jewellery. Prevent your jewellery from coming into contact with these chemicals.
- Avoid wearing jewellery made of different metals simultaneously since this may cause scratches or colour alterations.
- To prevent knotting, close the clasps of chains before placing them into your jewellery box.
- The colour of precious metals may alter when exposed to high temperature and damp environment. If such circumstance is encountered, please bring your jewellery to our store for inspection and cleaning.
- To prevent wear and tear, or abrasion with other jewellery, store jewellery in a fabric-lined pouch or box with separate compartments. At the time of purchase, all Chow Sang Sang jewellery is wrapped in a protective box, case or lined pouch. We recommend that you store it in its original case or another suitably lined box or pouch after each usage.
