Outstanding 37.73ct Apache Gold cabochon

Look at this gorgeous cabochon! The black clorite matrix of this piece shows ample chalcopyrite, sometimes refered to as fools gold, which is actually a high grade copper ore, and its metallic shimmer shows beautifully against its silky black host stone. This piece has fantastic size measuring 22.7mm x 4.7mm, and this piece is an all natural example and is ready to set.
