​Important Observations
​Origin & Enhancement: A disclaimer at the bottom of the card states that the origin and enhancement (treatments) were not checked for this specimen. This is a critical detail, as natural sapphires are often heat-treated to improve color, and untreated stones generally command a much higher market value.
​Visuals: The physical gemstone is visible in a small compartment on the right side of the case. It appears to be a very dark, deep blue oval-shaped stone.
​Authentication: The card includes a QR code and a round blue stamp from the Cambay Gemmological Lab, signed by a gemmologist.
​Note: While this certificate provides technical measurements, it does not provide a monetary valuation or an “eye-clean” clarity grade. If you are looking to verify the authenticity further, you can usually use the certificate number on the lab’s official website.
