About Ruby Jewelry
Ruby jewelry is built around the red variety of corundum, the same mineral that gives us sapphire. Chromium is what turns corundum red, and the stones with the purest red and a slight blue undertone are the ones the trade calls pigeon’s blood. Ruby sits at 9 on the Mohs scale, among the hardest gems used in jewelry, so it holds up to daily wear in a ring as well as in a pendant or necklace.
Treatment is the first thing to understand when you buy ruby. Most rubies are heated to improve color and clarity, a long-accepted practice that is stable for the life of the piece. Unheated ruby of fine color is rare and is priced at a premium. Some lower-priced rubies are instead filled with glass to hide fractures, which is a different and less durable treatment, so it is worth asking about before you buy.
Color runs from pinkish red to deep red. Buyers weigh how pure the red is, how light or dark the tone is, and how clean the stone looks in normal light. Origin adds to the price on top of that. Burmese stones carry the most historic value, while Mozambique and other sources supply strong color at more accessible levels.

Heated and Unheated Ruby
About 95% of rubies are heat-treated, which is standard, disclosed and accepted. Unheated stones, such as Burmese pigeon’s blood ruby, cost more per carat at top grades.

Ruby Jewelry Categories
Ruby’s Mohs 9 hardness makes it ideal for every jewelry category. Most popular:
- Halo and three-stone rings, with the ruby flanked by diamonds
- Ruby and diamond pendants, with a solitaire ruby in a diamond halo
- Stud and drop earrings
- Tennis bracelets, with ruby and diamond alternating
- 40th anniversary pieces, since ruby is the 40th anniversary stone
Yellow / rose gold amplifies ruby’s warm red; white gold and platinum create sharper modern contrast.
