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.
The indicator mineral suite contains grains that are indicative of diamond inclusion chemistry showing high chrome, low calcium G10D pyrope garnets.
On the basis of the type, the global garnet market is segmented into almandine, andradite, grossular, pyrope, spessartine, and uvarovite.

For the most part pyrope does not occur in collectible crystals; nevertheless, in "Pyrope from the Dora-Maira Massif" (Gilla Simon) collectors can learn about a geologically unique occurrence in Italy, and in "The Fiery-Eyed Volcanoes of Bohemia" (Jiri Kourimsky and Jaroslay Hyrsl) there's a sketch of the 2,000-year history of mining Bohemian gem pyropes which originate in Tertiary-age volcanic rocks.
The first of these is pyrope garnet, the name coming from the Greek word for fiery.
This property is host to pyrope beach sands dominated by favourable G10 pyrope mineral chemistry.
