Chrysoberyl Cats Eye Appraisal

Blue Cat's Eye Cabochon Gemstone

The item appears to be an oval, cabochon-cut gemstone, exhibiting a distinct blue color with a prominent chatoyancy effect, often referred to as a 'cat's eye' due to the bright, narrow band of light that runs across its surface. This phenomenon suggests the presence of very fine, parallel fibrous inclusions within the stone. The blue hue is deep and fairly saturated. Size-wise, it appears to be relatively small, likely suitable for inclusion in jewelry such as a ring, pendant, or earring. The surface seems polished and smooth, indicating good craftsmanship in its cutting. No discernible chips, cracks, or significant abrasions are visible from the provided image, suggesting it is in good to excellent condition. The lack of a setting implies it is a loose stone. Without further information, it's difficult to determine the exact material, but common gemstones displaying this effect include Chrysoberyl (the classic cat's eye), Tourmaline, Apatite, or various Quartz varieties. The specific shade of blue might also hint towards a synthetic material like lab-grown sapphire or glass, but the chatoyancy looks quite natural. There are no visible maker's marks or signatures as it is a loose gemstone. Its age and specific origin are impossible to ascertain from the image alone, but the cut and polish suggest a modern or contemporary piece of lapidary work. The quality indicator is the strong, well-defined chatoyancy, which is a desirable feature for such stones.
