What to look for in ruby

Ruby is red corundum. Read the lot's stated identity and any supplied report, alongside its colour description and photographs.

Ruby is routinely heated, and some material on the market carries glass or lead-glass filling in its fractures, which is a far more consequential treatment than heat. Every treatment we know of is written on the lot. Where we do not know, we say that instead of guessing.

  • The colour in different photographs, read alongside the stated identity. A photograph alone does not verify a mineral identification.
  • Filling, not just heat. Glass filling changes what the stone is and what it can survive.
  • Origin where it is known, and the absence of a claim where it is not.
