Certified Natural Blue Sapphire (Neelam): What to Verify
Treatment disclosure is essential on every blue sapphire certificate — heated vs. unheated changes both value and, in some classical astrological views, suitability. Origin claims deserve particular scrutiny for this gemstone specifically: "Kashmir" is the single most valuable and most frequently over-claimed origin in the entire sapphire trade, so any Kashmir-origin claim should come with independent origin-determination documentation from a recognized lab, not just a seller's word.
Our authenticity standard for Blue 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 Blue Sapphire Certification Questions
How do I verify a Kashmir-origin claim?
Ask specifically whether the report includes formal origin determination (not just a general quality certificate) from a recognized independent laboratory, and request to see that documentation before paying a Kashmir premium.
What does "unheated" mean on a sapphire certificate?
It means the lab found no evidence of heat treatment during examination — the stone's color and clarity are exactly as the earth produced them, which is significantly rarer and more valuable than heated material of similar visual quality.
