Protecting Gems in Sri Lanka

Caring for Your Gems

Our guidelines will help to protect your gems from discoloration and chipping.
Gems have different Hardness's on the Mohs scale of hardness.Sapphires hardness is 9 and Quartz (Amethysts, Citrines, Agates) is 7.
If gems of different hardness are placed together, the harder gems will scrape or chip the  the gems with a lower hardness.It is important to keep them separately.
Some gems have a property termed as "Cleavage".If the gem is subject to pressure like a fall or rubbing against each other or another gem, they can chip easily despite of their hardness, example Diamonds and Topazes.They " Fracture" in certain directions.
To enhance the colour, gemstones are subjected to irradiation (White topaz changed to blue).It is best not to expose these gems to direct heat as they often undergo a unpleasant colour change.
Pearls and corals are not categorized as gems,but considered as " Fine" Gem Material.They are organic and and have a very low hardness.To preserve them, occasionally wash with lukewarm soapy water, rinse and dry with a soft cloth.They must not be exposed to direct light.
To further protect them, keep them in soft cotton bags and not plastic ones.
