Collectors 5.70ct untreated bi-color Sphene!

Presented here today is a truly unique gemstone. This is an untreated, bi-color, color shifting sphene. And it's untreated! The rich brown and green colors of this piece are well defined, showing you exactly where the mineral content changed during its development, but the real eye catching part of this gem is that the rich brown and green display strong notes of yellow and red when seen in warmer lighting. And its all captured under superior luster. This piece has fantastic size measuring 16mm x 7.6mm x 4.5mm, and it has mixed translucency, with its brown to orange side showing full translucency, and its green to yellow side showing smoky translucency. Sourced from Russia.
