You can order crushed turquoise, cabochons, and bead strands from Thunderbird Supply, 928-526-2439. It runs $10 a bag for a bag about 2"x3". It's sky blue. Thing about cabs is you have ovals, freeforms, and rounds, and some squares. They will always be fairly irregular in shape, even ovals, because they have to follow what the stone wants. When asking for cabochons, you have to just specify an average size because each one will be different. In general on cabochons, you will have long ovals, ovals, rounds, and freeforms. They average about .98 cents a carat for Sleeping Beauty. Turquoise is sold by carat weight. Smaller ovals and rounds will be true oval and true round, but those are usually in the 4mm to 6mm sizes. After that, they will be following the stone. Those ones will be backed. Sleeping Beauty is the only one you can really rely on being sky blue. Kingman can vary from sky blue to shades of green.
