Natural Royston Pilot Mountain Fox Blue Gem Turquoise Polished 2 Specimen Nugget

Based on appearance, these appear be Royston turquoise specimen nuggets, or at least turquoise with very similar characteristics. However, there are several Nevada mines (like Pilot Mountain, Fox, or Blue Gem) whose material can look very close to Royston, and without mine provenance it’s almost impossible to be 100% certain just by sight. These two nuggets are perfect for jewelry making or just decoration. Each measure approx 2" x 1-1/2" and together they weight 75 grams.
