57ST467: Ruby Zoisite Rectangle 18x25mm - 15-16" Strand
Discovered in 1954, Ruby Zoisite or more accurately Ruby in Zoisite is a beautiful and colorful naturally occurring metamorphic rock found primarily in Tanzania. The black (hornblende) flecked deep green Zoisite is the perfect background to make the rosy hues of ruby truly pop! Zoisite is a relatively soft mineral, while Ruby is an extremely hard mineral. This variation of hardness means the stone can be rather difficult to cut and polish.
