Processing Bisbee Turquoise
Cutting Bisbee Turquoise

Cutting Bisbee Turquoise from rough material is reasonably easy if you have the proper equipment and knowledge. The first thing you must realize is that Bisbee Turquoise has not been mined, for the most part, since the 1970′s at the latest.  For this reason it is possible that it may have become dried out or unstable and should be cured in water to bring back some moisture in the rock before cutting.

Cutting Bisbee Turquoise from the rough material is done with a diamond saw. It is best to use a lot of water when sawing, I recommend using an cutting agent that can be found at a lapidary supply or having clean water running vigorously on the saw blade when cutting your rock.
I then back the Bisbee slabs, I use a resin mixed with pumice, plaster of paris or any other dirt type material to thicken the resin. I color it with cement coloring that you can get from you local cement company. I then use cement coated nails and glue the backed slabs on the nails with thick super glue and let them set up for 12 hours, I drill holes in a 2×4 to hold the nails in an upright position while drying.
You must have a lapidary machine and I prefer using diamond wheels for cutting, I use a Cab King that can be purchased from Kingsley North (http://www.kingsleynorth.com/skshop/product.php?id=94163). My machine is set up with 80, 220, 400, 600, 1200 and 3200 grit diamond wheels which I grind, shape and sand the slabs into cabochons, I process with all six cutting wheels. I then use a lapping wheel with Sapphire Powder to give my cabochons the final polish. Using this process will give you a beautiful glassy finish on your Bisbee Turquoise Cabochons or most any other reasonably hard gemstone material.
Finally, I remove the cabochons from the nails with a torch which heats the nails quickly. Once the cabochons are off of the nails I sand the back of the cabochons with my lapping machine or the 80 grit wheel to remove any excess glue. You can also use doping wax to ahear the stones to wooden dowels. If you do this make certain you let the cabochons dry for 6 hours, put them in the freezer for one hour and then quickly remove the stones from the doping sticks with a knife.

Cut Bisbee Turquoise StonesDillon and John Hartman of Durango Silver Company just completed cutting several hundred carats of Bisbee Turquoise which we will photograph and offer to other Jewelers and collectors on the Durango Silver Company website.

We have fabulous natural Bisbee Cabochons ranging in size, color and matrix configuration that Bisbee Turquoise entrepreneurs will absolutely love. This is a rare occasion to find Bisbee Turquoise for sale on the open market as the Bisbee Turquoise Mine has been closed for over 40 years and there is very little Bisbee Turquoise to be had.

Durango Silver Company has one of the largest Bisbee Turquoise collections in the world as they had purchased the balance of the Cecil Mickelson / Robert Mathews collection from the 1960′s. Robert Mathews and Brother-in-law Cecil Mickelson were partners in the only Turquoise Mining grant that was awarded by the Phillips Dodge Mining Company at Bisbee, Arizona.
