Amblygonite (Twinned)
Cabinet, 9.8 x 6.2 x 5.3 cm
Jenipapo district, Itinga, Jequitinhonha valley, Minas Gerais, Brazil
Amblygonite is a rare species in large crystals, occurring at its very best in this locality. This large crystal is a classic fishtail twin, which is unusually symmetric. Many are smaller, and off-balance. The size an dgeometry of this piece make it stand out. It is extremely sharp and complete all around 360 degrees except for only the most trivial edge wear in a few spots. One termination is slightly etched atop its tip, but is complete. Mass is 420 grams, or about 1 pound in weight. This specimen was featured in the exhibition "MINERAL DREAMS: Brazilian Gem treasures" at the Munich show of 2010.Joe Budd Photos
