Ruby, the July birthstone, is the most valued variety of the mineral corundum and one of the most coveted gemstones in history. Its intense red color, caused by chromium, has inspired comparisons to fire and blood across every culture. Top-quality Burmese rubies with 'pigeon blood' color can sell for over $1 million per carat at auction, surpassing even diamonds.
Traditional Birthstone
Ruby has been the traditional July birthstone since the very first birthstone lists. In ancient Sanskrit texts, ruby was called 'ratnaraj,' meaning 'king of gemstones.' Hindu priests believed rubies burned with an internal fire that could never be extinguished. Medieval Europeans wore rubies to guarantee health, wisdom, wealth, and success in love.
Modern Birthstone
The modern designation keeps ruby as the sole July birthstone. Myanmar (Burma) has historically produced the finest rubies, particularly from the Mogok Valley. Mozambique has emerged as a major source of high-quality rubies since 2009. Heat treatment to improve color and clarity is standard practice and fully disclosed. Unheated rubies of fine quality command significant premiums.
Symbolism & Meaning
Ruby symbolizes passion, courage, and protection. In ancient Burma, warriors inserted rubies into their skin before battle, believing the gems made them invincible. Ruby is associated with the heart chakra and represents vitality, life force, and romantic devotion. The Bible mentions rubies multiple times as among the most precious of all creations.
Historical Significance
Rubies have been mined in Myanmar for over 800 years. The Mogok Stone Tract produced many of the world's most famous rubies, including gems in the British Crown Jewels. Marco Polo wrote of the King of Ceylon's magnificent ruby. The Black Prince's Ruby in the Imperial State Crown is actually a large spinel, highlighting how rubies and spinels were confused until mineralogical advances in the 19th century.

Gift Guide
Ruby is the quintessential July birthday gift and the traditional gem for 15th and 40th wedding anniversaries. Ruby stud earrings, tennis bracelets, and solitaire rings are classic choices. For those seeking value, Mozambican rubies offer vivid color at lower prices than Burmese stones. Lab-grown rubies provide the same beauty and hardness for a fraction of the cost.
Care & Handling
Ruby is exceptionally durable at Mohs 9, second only to diamond. It is suitable for everyday wear in any jewelry setting, including rings. Ultrasonic and steam cleaning are generally safe for heat-treated rubies. However, fracture-filled or cavity-filled rubies require gentle cleaning with warm soapy water only. Have ruby jewelry inspected annually to ensure settings remain secure.
