Garnet
There are different groups of garnet, almandine, spessartine, pyrope, grossular, andradite and uvarovite. Not all are red, though red is typically the most common colour of garnet.
Garnet is a powerful invigorating and regenerating stone. It purifies and balances energy. It is said it was a protective stone so a few talismans are made of garnet. It inspires devotion and love, and is an exceptionally good stone to have in a crisis as it has a fortifying effect and gives us courage. Square-cut garnets are said to bring success to business ventures.
