Bright Apple Green Turquoise Ring in Sterling Silver Size 9

Previously owned sterling silver ring set with bright apple green turquoise. The color of this turquoise is very similar to Mojave Green, but has no bronze matrix. This stone may be dyed as Mojave Green is. Might be natural Nevada green turquoise, but my guess is dyed. In any case this is a beautiful bright stone that is real turquoise. 

Ring is a size 9 and the face measures 1" long by 1//2" wide. Weight: 6.7 grams. Not Native American made. Marked 925 inside the back of the band.
