Gem knowledge

Garnet — the rainbow family you thought was red

Garnet is a family, not a colour — red is only its most famous member.

Garnet is not one red stone; it is a mineral FAMILY spanning a rainbow.

The maker's note — garnets are untreated in most cases (rare honesty
bonus), take polish beautifully, and survive bracelet duty.

Family comparisons like this one recur through the gem webinar
replays
— identification included.

What students say

“I will use the skills acquired to make pieces for family, friends and of course, myself! If I could get to a point of eventually selling pieces, even better!”

— Elena A. (Australia) · published student feedback

“The skills learnt help me in choosing my purchases. I may consider helping a relative in the jewellery business and get included in the exhibitions.”

— Joyce T. (Singapore) · published student feedback
