AI Appraisal Estimate

The image displays a laminated identification certificate, titled 'Identification Certificate Of Gems & Jewelry' (NQTC), referring to a piece of jewelry pictured on the card. The depicted item on the certificate appears to be a green, translucent key-shaped pendant with a heart-shaped bow, consistent in appearance with jadeite. The document includes several fields of technical data: a total mass of 4.18g, a refractive index of 1.66, and a density of 3.33. Text on the card includes a 'Conclusion' reading '翡翠(A货)', which typically refers to 'Grade A' jadeite, though this remains unverified without physical testing of the actual stone. The certificate bears various serial numbers, including 'HL12012220044', a QR code, and signatures for an identifier and a tester. While the document presents itself as a formal gemological report, the authenticity of both the certificate and the jewelry item it represents cannot be established from a photograph alone; such documents can be reproduced or may not accurately correspond to the physical item in hand. The card is shown in a clear plastic sleeve and appears to be in good condition with no visible creases.

Based on the image provided, I have examined a laminated identification certificate labeled 'NQTC' which describes a green, heart-shaped key pendant. The document suggests the item is 'Grade A' jadeite weighing 4.18g. From this photo alone, I can see the certificate has standard indicators of gemological reporting, including a QR code and signatures, but I cannot verify the legitimacy of the document or whether it corresponds to the actual physical stone. The authenticity of the jadeite—specifically the absence of chemical treatments or polymers—would need physical inspection under a Chelsea filter and spectroscopic analysis to confirm. My valuation assumes the hypothesis that the pendant is indeed Grade A jadeite as described. The market for jadeite varies wildly based on transparency, 'water', and color vibrancy. If the attribution is correct, similar small pendants typically sell in the $150 to $450 range in secondary markets. However, if the stone is lab-grown, treated 'Grade B/C' jade, or a simulant like nephrite or aventurine, the value would likely drop below $20-$50. To provide a more accurate valuation, an in-person examination by a certified gemologist and verification of the certificate's serial number through the issuing laboratory's database would be required. The current estimate depends entirely on the accuracy of the documentation shown, which remains unverified.
