This is a very nice set of Royston Turquoise Cabochons weighing at total of 91.5 carats. These natural gemstones are in the same color range and match good enough to make a Jewelry set. They have a good Turquoise color and have a green two tone quality, the golden brown matrix has a good configuration. These stones have been lightly backed as is standard in American when cutting Turquoise.
The Royston mining district is a group of old Nevada Mines that produce a beautiful medium blue to dark green turquoise with brown matrix. Once in a while you will get a stone that is blue to green fade as well as emerald green stones. This is vein
and seam material. View Dillon’s video about the filming of the Royston Turquoise Mine with the Travel Channel - http://www.youtube.com/watch?feature=player_embedded&v=lZ6ruADOReI
