Although magnetic signatures of known kimberlites are not indicative of diamond content, the potential of the Stein cluster of high interest targets is further reinforced by heavy mineral samples collected down ice which contain indicator mineral grains that are indicative of diamond inclusion chemistry showing high chrome, low calcium G10D pyrope garnets. Stein is a permitted, advanced diamond exploration project having the benefit of numerous successive exploration campaigns and over $1.5 million in previous expenditures.
The cushion-shaped brooch pictured here is set with pyrope garnets, which are the commonest variety of this gemstone.
