Loose Oval Brilliant Cut Colorless Gemstone

This item is a loose, colorless faceted gemstone presented on a black velvet display pad. Based on the visual inspection, the stone exhibits an oval brilliant cut, characterized by an elongated rounded outline with multiple flat-planed facets designed to enhance light return. The stone appears to be of significant carat weight, likely exceeding 1.00 carat based on its scale relative to the display box. In terms of color, the stone appears colorless to the naked eye under the current lighting conditions. The clarity is difficult to assess definitively without magnification, but there is prominent internal light reflection and sparkle, suggesting a high refractive index. However, the presence of visible abrasions on the facet edges and potential 'chips' or roughness along the girdle suggests that the stone may have been previously set or handled extensively. While identified as a diamond in the user context, the visual luster and certain facet arrangements could also be consistent with alternatives like cubic zirconia or moissanite. No laser inscriptions or maker's marks are visible in this view. The velvet display pad shows significant lint, dust, and loose fibers, which may occlude finer details of the stone's base.
