A quick-reference guide to caring for your gemstones

Enticing and dazzling, gemstones have fascinated people since ancient times, due to their varied colours, shape, and brilliance. Their rarity and natural toughness make them precious and prized possessions. But despite their tough nature, gemstones must be looked after if they are to have long and lustrous lives.

For cleaning, most gemstones will respond well to warm water, mild detergent, and a soft brush at home. However, some gems do have sensitivities. Familiarise yourself with these, particularly if you decide to have them cleaned mechanically, whether at home or professionally.

Here is a quick guide for gems that require extra care to maintain their beauty.

Amber: Avoid chemicals and ultrasonic cleaning.

Beryl: Avoid ultrasonic and steam cleaning.

Coral: Avoid chemicals and solvents.

Emerald: Avoid chemicals and ultrasonic cleaning.

Lapis lazuli: Avoid chemicals and ultrasonic cleaning.
