Lapis Lazuli, often abreviated as "lapis", is a semi-precious stone prized for it`s blue color. Lapis is not a mineral, because it is made from many other minerals to form a rock.
Im happy with the stones, so happy in fact that I went out and placed another order yesterday. Im delighted to be a new customer. Thank you for the follow up phone call and email. Your customer service is excellent!
