AI Appraisal Estimate

This item consists of two loose, oval-shaped cabochon gemstones, identified by their characteristic olive-green hue as peridot. Each stone features a smooth, domed convex top and a flat base, a cut designed to emphasize the richness of color and the stone's inner glow rather than light refraction through facets. The gemstones exhibit a vibrant, yellowish-green saturation typical of high-quality magnesium-rich silicate minerals. In terms of size, they appear to be approximately 6-8mm in length, though an exact measurement would require a caliper. The translucency is high, with a vitreous luster that reflects light sharply off the polished surfaces, as seen in the white highlights. While the image resolution is limited, the stones appear to have 'eye-clean' clarity with no immediately visible Lily Pad inclusions characteristic of this gem variety. There are no obvious signs of surface chipping, abrasions, or scratches along the girdles, suggesting they are in excellent, unwrought condition. These stones are likely contemporary in age, intended for use in custom jewelry settings such as stud earrings or as part of a multi-stone ring design. The symmetry of the polish and the matching color profile indicate a well-calibrated pair of commercial-to-fine gemstone quality.

I have virtually examined this pair of oval cabochon peridots. Based on the olive-green saturation and translucent vitreous luster, the stones appear to be genuine peridot or a high-quality glass simulant. The stones, estimated at approximately 2.0 to 2.5 carats each, display a consistent, 'eye-clean' medium-vibrant yellowish-green hue. The polish is superior with no visible surface-reaching fractures or abrasions, suggesting recent cutting and careful handling. In the current wholesale and secondary markets, peridots of this size and cut are valued for their consistent calibration, making them ideal for earring sets. While peridot is not a rare mineral, matching pairs with this level of clarity and color saturation command a slight premium over single loose stones. Limitations to this appraisal include the inability to perform refractive index (RI) testing or microscopic analysis to identify characteristic 'lily pad' inclusions which confirm natural origin. A definitive appraisal would require a physical inspection using a refractometer and 10x magnification to rule out synthetic spinel or green cubic zirconia. Furthermore, verifying the exact carat weight via a precision scale and checking for any thermal treatments would be necessary for a localized market valuation. The stated estimate assumes these are natural, untreated earth-mined gemstones.
