Ruby Jewelry

Ruby is the red variety of the mineral corundum, the same mineral family as sapphire. Its red color is produced by chromium trace elements in the crystal structure. Ruby is rated 9 on the Mohs hardness scale, making it the second hardest gemstone. Its value comes from the combination of hardness, vivid color, and natural rarity: fine-quality rubies in vivid red with good transparency are among the rarest gemstones in nature, and the finest specimens reach some of the highest per-carat prices of any colored stone.

Pigeon's Blood is a trade term for the most prized ruby color: a vivid, pure red with a slight blue undertone and strong fluorescence that creates a glowing appearance under incandescent light. The term originates from historical Burmese ruby descriptions and was associated specifically with Mogok Valley stones, though GIA and other laboratories now apply it to the color standard regardless of geographic origin. Rubies described as Pigeon's Blood quality command the highest premiums in the fine colored stone market.

Fine-quality rubies in vivid Pigeon's Blood color are significantly rarer than comparable-grade diamonds. Diamonds are found across many global deposits; top-grade natural rubies in vivid, unheated, pure red are found in very limited supply, primarily from specific locations in Myanmar, Mozambique, and a few other sources. At the finest quality levels, rubies are among the rarest gemstones in the world, and exceptional stones regularly set records at auction.

Heat treatment applies high temperatures to rubies to improve color and reduce clarity-reducing inclusions. It is a permanent, stable treatment and is standard practice across the trade: the vast majority of commercial rubies are heat-treated. Unheated rubies that achieve excellent color and clarity without treatment are significantly rarer and command substantial premiums, particularly when certified by a reputable laboratory. Heat treatment does not reduce the stone's durability or beauty.

Ruby shares the same 9 Mohs hardness as sapphire, placing it second only to diamond at 10. In practical terms, rubies can only be scratched by other rubies, sapphires, or diamonds. This makes ruby one of the most durable gemstones for fine jewelry, particularly for rings and bracelets where the stone experiences the most surface contact. Gemstones below 7 on the scale, including opal and pearl, are significantly more vulnerable to surface damage during regular wear.

Ruby is the birthstone for July. It is also associated with the 15th and 40th wedding anniversaries in traditional anniversary gift charts. Ruby's association with passion, vitality, and protection has made it one of the most symbolically significant gemstones across cultures, appearing prominently in royal jewelry, religious artifacts, and betrothal pieces throughout history.

Yes. Lab-created rubies are chemically, physically, and optically identical to natural rubies. Both are corundum with chromium that creates the red color. Both carry the same 9 Mohs hardness. The only difference is origin: natural rubies form in geological environments over millions of years; lab-created rubies grow in controlled facilities in weeks. Lab-created rubies are not imitations or simulants. The primary reason buyers choose natural rubies is the value placed on natural origin and rarity.

Ruby bracelets include tennis-style pieces with continuous matched rubies, channel-set bangles, and chain bracelets with ruby accent stones. Ruby tennis bracelets are the most formal option; ruby accent chain bracelets are the most versatile for everyday wear. Lab-created ruby bracelets provide more consistent color matching across the full length. See our ruby bracelets for the current selection.

Ruby and sapphire are the same mineral, corundum, and share identical hardness and care requirements. The buyer choice is purely about color: ruby delivers vivid red; sapphire delivers blue, pink, yellow, or other sapphire colors. Ruby is generally rarer in fine quality than sapphire, which typically makes comparable rubies more expensive per carat. Both are among the most durable colored gemstones and suit all jewelry types equally. For the sapphire range as an alternative, see our sapphire jewelry hub.

Diamond jewelry emphasizes colorless sparkle and light dispersion; ruby jewelry emphasizes bold, vivid red color. For formal occasions, both read as fine jewelry but create very different visual effects. Diamonds are more versatile across all outfit colors and styling contexts; rubies make a more deliberate color statement that pairs best with specific clothing colors. For buyers who want fine jewelry without gemstone color, see our diamond rings for the diamond option.
