Peridot is one of the few gemtones that occur in only one color; an olive-green.

It is 6.5 -7 on the Mohs hardness scale. Large peridot are rare.
Peridot gemstones symbolize the sun and helps manifest feelings of inner warmth and well-being. It brings positive vibes that open the heart up to joy and abundance.
