Certified Natural Yellow Sapphire (Pukhraj): What to Verify
The most important line on a yellow sapphire certificate is treatment status — heated or unheated — since this both drives price and matters specifically for astrological sourcing, which traditionally favors unheated Pukhraj. Equally important is species confirmation: the certificate should verify the stone is genuine corundum, not heat-treated citrine, golden topaz, or synthetic sapphire, all of which are commonly mis-sold under the Pukhraj name to buyers who don't request independent verification.
Our authenticity standard for Yellow Sapphire
Whenever a certificate is available, it's shared with you before you pay — the same commitment described in full on our site-wide Authenticity & Certification page. Because our dealer network sources through multiple independent gemological laboratories, the specific issuing lab may vary by stone; what stays constant is that the report is independent, not a seller's own letterhead.
Once you have a report number, most independent laboratories offer free online verification — compare the certificate in your hands against what the lab's own database shows before finalizing any purchase.

Common Yellow Sapphire Certification Questions
What treatment disclosure should I look for on a yellow sapphire certificate?
The certificate should state plainly whether the stone is heated or unheated. Given how common heat treatment is in this stone, an unclear or missing statement is a reason to ask before buying, not to assume the best case.
Can a lab confirm a yellow sapphire is really corundum and not another gem?
Yes — standard gemological testing (refractive index, specific gravity, and spectral analysis) reliably distinguishes corundum from citrine, topaz, and other yellow stones commonly substituted for Pukhraj.
