Common treatments

Rhodolite garnet is easily recognised by its colour, a very appealing purplish red.

Garnet’s medium hardness makes this stone quite easy to scratch.

Care and cleaning

keep the rhodolite away from heat, thermal shocks, ultrasound and blowtorch as it might cause cracks.

Handle with care and store separately to avoid any risk of abrasion.

Clean with warm soapy water and dry with a soft cloth.
