Top 10 Fascinating Facts About Rubies

Rubies are not just any gemstone—they are symbols of passion, protection, and prosperity. Coveted throughout history and across cultures, these vibrant red gems have stories and qualities that make them stand out in the world of precious stones. In this blog, we dive into the top 10 fascinating facts about rubies that showcase their unique allure and enduring value.

1. The King of Gems
In ancient Sanskrit, rubies are called "Ratnaraj," which means "king of precious stones." This regal title reflects the high esteem in which rubies have been held throughout history, symbolizing wealth, power, and passion.

2. Color is Key
The most sought-after color in a ruby is called "pigeon's blood"—a pure red with a hint of blue. The color of a ruby is the most significant factor in its value, with the brightest and most vivid reds fetching the highest prices.

3. Family of Corundum
Rubies are a variety of corundum, the same mineral family that sapphires belong to. The presence of chromium in corundum is what gives rubies their distinctive red color, separating them from their sapphire relatives. All other colours of corundum are deemed sapphires. 

4. Durability and Hardness
Rubies score a 9 on the Mohs scale of hardness, making them one of the hardest natural gems in the world. This hardness makes them an excellent choice for everyday wear, especially for pieces like engagement rings.

5. Geographical Sources
While Myanmar (formerly Burma) is historically famous for producing the finest rubies, these gems are also mined in countries like Thailand, India, Madagascar, and more recently, Mozambique, which has become a significant source.

6. Ancient Warrior Gem
Historically, rubies were embedded into the armor of nobles and warriors. They believed that rubies were stones of protection, capable of ensuring safety in battle.

7. July's Birthstone
Ruby is the birthstone for July, making it an ideal gift for those born in the middle of summer. It's also traditionally given on the 40th wedding anniversary although more recently is popular for the 15th Anniversary. 

8. Fluorescence
Some rubies exhibit fluorescence when exposed to ultraviolet rays, emitting a glow that enhances their color. This effect makes them appear even more vibrant under certain types of lighting.

9. Healing Powers
In traditional medicine, rubies were believed to cure inflammatory diseases and soothe anger. They are also thought to bring good fortune, a belief that continues to make them popular in engagement rings and other fine jewelry today. 

10. Auction Records
Rubies hold records for per-carat prices among gemstones at auctions, demonstrating their sought-after status. The most expensive ruby ever sold was Estela de FURA, a 55.22 carat ''pigeon's blood'' natural unheated Ruby from Mozambique. It was unveiled by Sothebys in Dubai in May 2023, sold for $34.8 million which is the largest and most valuable ruby ever to appear at auction to date. 

Whether as part of a royal crown, a statement piece in a modern jewelry collection, or a symbol of love and commitment in an engagement ring, rubies continue to captivate and charm with their intense color and enduring strength.
