Afghan Green Hauyne 0.150ct Loose Stone with Certificate
Hauynite captivates with its striking neon blue. It is one of the rare stones said to be produced only in Germany and currently not commercially mined. Large specimens are rarely found, and it is also a gemstone that tends to have relatively many inclusions. Considering its low hardness, one can appreciate how precious it is for it to become a gemstone. This vibrant blue is an enchanting color that once seen, is hard to forget. Please enjoy its beautiful hue right in your hands.
This is a high-quality cushion-cut green hauynite with excellent clarity and rich color. An identification certificate is included.
