This is a really nicely done and highly unusual studio piece circa 1960's. It has a very cubist feel to it and is unique custom crafted with agates bezel set in sterling silver (acid tested). It is reversible and each side has different colored stones. It is very heavy and well made weighing 40.5 grams and measures 2.25 inches by 1 ⅛ inches wide. The tiger eye has a hairline crack in the lower corner, otherwise condition is very good.
