Blue Oasis is a claim near Tonopah Nevada. It has been known under other names including Tonto Springs. It is now part of the Otteson Brothers claims under the name Desert Oasis.
 
This cab weighs 30.4 carat and measures 3.25cm X 1.25cm. It is priced at $10 a carat or $304. It is not treated and is backed. I have assigned a TG of 85 or VHG. I purchased the stone from the miner Gre Fink who was working the claim.
