Lab-certified gemstones

Lab-Certified Blue Sapphire (Neelam) نیلم

In short: A lab report on a blue sapphire (Neelam) confirms three things that change its value: that it is natural corundum, whether it has been heated, and whether anything else was done to it, such as diffusion or glass filling. Send any Neelam's link on WhatsApp, and you see the report before you pay.

A lab report on a blue sapphire tells you three things that change its value: that it is natural corundum, whether it has been heated, and whether anything else was done to it.

Lab-certified listings will appear here as independent reports are added to individual stones. Until then, any stone can be sent for an independent report before you pay — ask on WhatsApp.

What the lab checks on blue sapphire

  • Heating: the lab studies the silk (fine needles) and crystal inclusions. Heat dissolves silk and leaves altered inclusions with tell-tale halos.
  • Diffusion: beryllium or titanium diffused into the surface to add colour. Advanced instruments detect this.
  • Glass filling: fractures filled with lead glass, seen under magnification as flash effects and gas bubbles.
  • Synthetics: flame-fusion stones show curved growth lines and round bubbles; flux-grown stones show flux residue.

Some labs also give an origin opinion for sapphire.
