Colombian Trapiche Emerald (from Cosquez) 0.157ct Loose Stone with Certificate
Trapiche emeralds, which display six distinct rays, are a rare and precious gemstone, accounting for only a tiny fraction of all emeralds produced. This pattern is believed to be formed when impurities become mixed with the crystal during its growth and extend vertically along with the crystal.
While most trapiche emeralds on the market come from the Muzo mine, this particular one is from the rare Cosquez mine. Furthermore, we have carefully selected pieces with deep body color and beautiful patterns. This particular lot was acquired by Masahiro Shimizu, the "Emerald Hunter" familiar from the TV show "Matsuko no Shiranai Sekai," for his overseas collection, and was first unveiled in Hong Kong.
