Sunstra – Garnets and Fresh Water Pearls

Garnet is a group of closely related minerals that share the same crystal structure but differ in chemistry. Garnets come in almost every colour, from deep purplish reds to oranges and greens.

Birthstone

January

Hardness

6.5–7.5 (Mohs)

Everyday wear

Garnet has fair to good toughness and is durable enough for jewellery, but it should be kept away from hard knocks and rough wear.

Care

Warm, soapy water is always safe; ultrasonic cleaning is usually fine unless the stone has fractures, and steam cleaning is not recommended.

Meaning and tradition

Garnet's name is linked to the deep red of the pomegranate, and in Indian astrology it is associated with self-confidence and mental clarity; in medieval times it was thought to calm an angry heart. Rhodolite is associated in modern crystal lore with warmth, affection, love and self-confidence.

Pearls are formed by molluscs, which coat a nucleus or irritant with layers of nacre. Natural pearls form without human help, while cultured pearls are grown with human intervention.

Birthstone

June

Hardness

2.5–4.5 (Mohs)

Everyday wear

Pearls are very soft and easily scratched, so rings and bracelets need protective settings or occasional wear; necklaces and earrings are easiest to enjoy.

Care

Put pearls on after perfume, hairspray and cosmetics, and wipe them with a very soft cloth after each wear. Never use ultrasonic or steam cleaners; for an occasional deeper clean use warm, soapy water and let strung pearls dry completely before wearing.

Meaning and tradition

In European tradition pearls symbolised modesty, purity and chastity, and many cultures linked their round shape with the moon. In ancient Chinese folklore pearls were believed to guard against fire and fire-breathing dragons.
