History

1996

History of John Dyer and Precious Gemstones Co. Partnership formed between John and David Dyer - Precious Gemstones Co. is born.

Trip to Zambia for emerald and aquamarine rough amid the background; Giving some of the rough gems to a faceter for cutting they were outraged by the price charged and the poor quality of the cutting (indeed, two of the three emeralds that were cut were so badly faceted that after not selling for a number of years they had to be recut) John decided to take matters into his own hands with the purchase of his first Ultra Tec faceting machine. While the struggling new business was getting on its feet John's cutting skills were improving as he pored over gemstone faceting books. His trial and error methods began to pay off as beautiful, sparkling gemstones began to emerge from his cutting wheel.
