Ruby is the red variety of corundum, the same mineral species as sapphire; chromium gives it its red color. Each ruby here is listed individually, with its own photographs, video and laboratory report details on its product page. For rubies over 1 carat with GIA reports, see our ruby over 1 carat collection.
What Each Listing Tells You
Every product page sets out the details of that stone's laboratory report, such as weight, measurements, shape, cutting style and color. Each listing states whether the stone is heated. Where the stone's laboratory report carries a treatment entry, we give it exactly as printed. Where a stone has a GIA report, its listing gives the report number; where a stone has a report from another laboratory, its listing names that laboratory.
Origin
Where a GIA report gives a geographic origin, the listing prints it together with GIA's caveat that any statement on geographic origin is an expert opinion. Where a stone's report gives no origin opinion, the listing says so, and any origin we name is our own sourcing record, not a laboratory finding.
Choosing a Ruby for Jewelry
Every ruby here is sold loose, so your own jeweler can set it in a ring or a pendant. Plan the setting around the individual stone's measurements, which are on its listing. Ask us for more images or video of any stone before you decide, and where a stone has a GIA report, check its number on GIA's own Report Check service at reportcheck.gia.edu.
