H5 Please see photos for details and condition. We do not guarantee the identity or authenticity of any gemstone unless it is accompanied by documentation from a recognized gemological laboratory. Our gemstone identifications are based on our experience and are determined through visual inspection, including hardness testing when appropriate and examination under 10x magnification. These methods allow us to identify what we believe to be the most likely gemstone; however, they are not a substitute for advanced gemological testing. Buyers should make their own determination prior to bidding, as all gemstone identifications are offered as our professional opinion and not as a guarantee.
