The lovely dark sea green round seraphinite gemstone cabochon shown here is 21mm long, and is available to be handcrafted into a custom made ring or pendant for you.
The word seraphim refers to angels, and seraphinite is supposed to have gotten its name due to its resemblance to feathers. Seraphinite is mined in a limited area of eastern Siberia in Russia. It was originally known as green chlorite.
Seraphinite is believed to promote self healing and aid with contacting the spirit world.
