Does every ruby come with a lab report?

No, not automatically. If you want one, any stone can go for independent lab testing at your request, and you see the report before you pay.

What will a lab report on ruby tell me?

It names the stone, says whether it is natural or synthetic, lists any treatment the lab is able to detect, and records the weight and measurements.

In short: With ruby (Yaqoot), a lab report earns its keep on treatment: heated, glass-filled and unheated rubies can look alike but sit at very different values. The lab also catches synthetics and look-alikes such as red spinel and garnet. Send us the link to any ruby on WhatsApp and you see the report before you pay.

With ruby, a lab report matters most for treatment. Heated, glass-filled and unheated rubies can look very similar on the table, but they are worth very different amounts.

What a lab looks for in a ruby

Heating: changed inclusions and dissolved silk show the stone has been heated, and sometimes flux residue sits inside healed cracks.
Lead-glass filling: badly cracked rubies filled with glass, often sold as "composite ruby", show blue flashes and trapped bubbles.
Synthetics: flame-fusion and flux-grown rubies are common. The lab looks for curved growth lines and flux patterns.
Look-alikes: red spinel, garnet and glass are separated using refractive index and spectroscopy.
