Crystals needing special care

Certain crystals are more easily damaged than others so require special care.

Amber

• This is easily scratched and should be stored in a soft material – silk/velvet
• To clean amber – use a mild soap and lukewarm water and polish it dry with a soft cloth
• Rubbing it with virgin olive oil also helps restore lost lustre.

Opals

• These contain up to 10 per cent water and should not be kept near heat sources, which can cause them to crack; or in dry places as this will cause them to lose their colour.
• Store opals in a small container of water.

Pearls

• These contain up to 2 per cent of water and, like opals, must not be kept near heat
• Do not expose them to acidic liquids such as vinegar or red wine, as this might cause them to dissolve.
