Outstanding 5.20ct glistening Sphene set

Wow! What a great set of gems. The bright greenish yellow hues really pop, giving them a vibrancy that is not common in most gemstones. Sphenes are one of the only gemstones besides diamonds that have this refractive quality. They are all matched in cut and color, measuring from 3.8mm to 4.2mm each with great clarity. They have a Mohs hardness rating of 5.5, and are untreated. Sourced from Madagascar.
