Purple-Blue Oval Faceted Loose Gemstone

This is an unmounted loose gemstone, presented in a white plastic protective case with a white foam insert. The gemstone is an oval-shaped, faceted stone displaying a deep purplish-blue color. The facets are clearly visible and appear to be well-cut, allowing light to reflect and refract, creating noticeable brilliance and flashes of lighter purple and blue hues. The color distribution appears relatively even throughout the stone, although some darker zones are visible under direct light. The surface of the stone appears mostly smooth with some minor surface wear or inclusions visible upon close inspection. The clarity appears to be at least partially transparent. The size is not specifically stated but appears to be of a moderate size suitable for setting into jewelry. Without further testing, the specific type of gemstone cannot be definitively determined from the image alone, but possibilities include Iolite, treated Topaz, or a type of Garnet, among others. There are no visible markings or inclusions that are immediately apparent as detrimental to the stone's overall appearance, suggesting a reasonable level of quality for a colored gemstone of this type. The protective case is a standard clear lidded plastic case with a beveled edge on the lid.
