Taaffeite is one of the rarest and most desirable of collector's gemstones, which often misidentified as spinel. The primary difference between spinel and taaffeite is the double refraction found in the latter and this the property we use to separate the suspect stones for further evaluation to find beautiful rare gems, like this beautiful purple 3.44-carats Taaffeite from Tunduru, Tanzania.

Black Opal is a greenish type of opal with black mottling and gold flecks. Usually found in ancient hot springs, the gem is usually tumbled smooth and cut cabochon. The phrase in the North "Black as a black opal" means, effectively, not very black (or evil) at all, and is used to describe good-hearted rogues and similar individuals who would be embarrassed by praise. A typical specimen has a base value of 1000gp.
