The Aquamarine crystals used for this piece were mined in Colorado on Mt. White, which is 
located just South of Mt. Antero.  Robert used three of those crystals and cut one 6mm and two 4mm round gemstones, weighing a total of 1.3 carats. The two 4mm gems match, and are slightly darker then the center 6mm gem.  He set them in this Size 7 Sterling Silver Ring.
