Loose gemstone, cushion-cut orange corundum (unauthenticated)

The item is a loose, faceted gemstone featuring a vibrant orange hue with reddish undertones. It has been cut into a cushion shape with rounded corners and faceted pavilion and crown facets that produce visible light reflection and internal fire under lighting conditions. The gemstone rests on a white insert within a transparent circular container, which is positioned on a light-colored, reflective metallic or plastic surface where faint letters reading 'VILION' are partially visible in the background. The visual characteristics—such as the color saturation and facet geometry—are consistent with corundum varieties like sapphire or padparadscha-type stones, though physical testing via refractometer or spectroscopic analysis would be required to verify mineral identity and treatment status. The user-supplied context states the material is a sapphire with a weight of 1.325 carats, but this claim is entirely unverified from the photograph alone. No maker's marks, hallmarks, or certification documents are directly readable in the image. The identification in the name rests purely on the visual appearance of a faceted, cushion-cut colored gemstone.

Based on what I can see in the photograph, I am examining a loose, faceted gemstone featuring a vibrant orange hue with reddish undertones, cut into a cushion shape. Per user submission, the owner identifies this as an unauthenticated sapphire weighing 1.325 carats. However, I cannot verify mineral identity, exact carat weight, clarity grades, or treatment status from a photo alone; physical testing via refractometer, microscopic examination, or spectroscopic analysis would be needed to confirm these factors. Assuming the owner's claim is correct and the stone is indeed a natural corundum of this type and color saturation, comparable loose colored sapphires in this size range typically command an estimated market value between $1,500 and $3,500, depending heavily on the presence of heat treatments, color zoning, and overall brilliance. If further testing reveals the item is a synthetic lab-created corundum, a less valuable imitation material, or a different gemstone variety altogether, the market value would decrease significantly, likely ranging from $100 to $400. To establish an established fact regarding its identity, an in-person examination and a formal grading report from a recognized gemological laboratory would be required.
