The world's largest carved emerald

The emerald, discovered at Carnaiba, in the emerald-producing province of Bahia, Brazil, in August, 1974, made its way to Palo Alto via a local gem trader with whom we had worked and partnered for many years.

The original weight of the emerald was 62 pounds, or over 140,000 carats. Its dimensions then were approximately 16 1/2" high, 14" wide, and 7" deep... the final weight after carving is 86,000 carats, or 38 pounds. The excess material ended up as dust on the studio floor...
