15 ctw. Old stock! 50s-80s USA-100% Natural Turquoise 
 This material is out of some old buckets of turquoise I was fortunate to come across a few years back!
This material was mined & much of it was slabbed between 1950 & 1981. The lapidary who was cutting all this stone passed on & left it to his wife who got tired of having all these buckets taking up so much room in the garage she then sold it to a friend of mine in the 90s who in turn sold it to me & this is the last of approx. 2000 Lbs. This is out of my stash that I have been cutting for the last 3-4 Years. I have found cut & shared with you here on ebay all types of turquoise. Bisbee, No. 8, Morenci, Kings Manasseh, Royston, Kingman, Sleeping Beauty, Stormy Mountain, etc. Many of the buckets were marked as Bisbee, Mineral Park, kingman, L.W Hardy to Sunbell corp. etc. Look close as I do not have the time or the patience to identify all the different turquoise that is up to you. Every piece is interesting! In fact some of the buckets that said scrap yielded some of the most interesting specimens! 
Thanks! I hope you Enjoy!
