Ithaca Peak Turquoise–Amazing! This turquoise is loaded with Pyrite, giving the turquoise some sparkle, and it is all natural. The gorgeous blue on this one really pops. Great for your casual wardrobe and for the turquoise lover. This turquoise comes from Arizona–just gorgeous! It is set into my handmade sterling silver setting with a comfortable tapered band and fits a size 8 finger.
