About the stone

What is Grossular?

Grossular is the calcium-aluminium garnet. It comes in many colours — pale green, gold, orange and the cinnamon-orange variety hessonite.

Its name comes from the Latin for gooseberry, after its pale green colour.

Care & cleaning

Clean with lukewarm water, a drop of mild soap and a soft brush, then dry with a soft cloth. Store apart from softer stones to avoid scratches.
