The name is derived from the Latin word ruber, meaning ‘red’ – the color of love and passion

Rubies are a variety of corundum that has no coloration. The vivid red colour comes from trace amounts of the element chromium (Cr) - which ranges from an orangy red to a purplish red. The finest colour is called pigeon’s blood in the trade - a deep red colour with a hint of purple.

However, it wasn’t recognised as a variety of corundum until 1800. Prior to that, red spinel, tourmaline, and garnet were also believed to be ruby. Even the Black Ruby, one of the famous crown jewels of England, was considered one of the largest cut rubies until determined to be a spinel.




Symbolic of passion, protection, and prosperity, ruby gemstones have been revered since ancient times. In India, the ruby is still considered the “king of precious stones” (ratnaraj) for its rarity, hardness, beauty, and mystical powers. In past centuries, people believed it could predict misfortune and danger, cure inflammatory diseases, and soothe anger.

Even medieval Europeans thought rubies to bestow health, wisdom, wealth, and success in love.  
Due to their blood-like colour, rubies always encouraged strong associations with this life-sustaining fluid. 
In ancient Burma, the ruby was the stone of soldiers. They believed it bestowed invulnerability, and only those who had rubies physically inserted into their flesh would gain this benefit. Soldiers believed they were safe from wounds, spears, swords, or guns.
In addition, rubies were popular talismans: according to people, wearing the stone on the left - the heart side - would allow the bearers to live peacefully and avoid all perils.  


Myanmar, most specifically the Mogok area, is one of the oldest sources of fine rubies. Since the late 20th century, Vietnam has also been an important source. Other important producers are Mozambique, Thailand, Cambodia, Afghanistan, Tajikistan, Pakistan, Sri Lanka, Kenya, Tanzania and Madagascar.  


All you need is a bowl, warm water, gentle detergent, and a toothbrush with soft bristles. To remove dirt and oils, dilute the soap in warm water and soak your loose rubies in it for a few minutes or even overnight. You can also use the toothbrush to clean your stones and wipe them dry with a lint-free cloth.  
Ultrasonic and steam cleaners are usually safe for untreated, heat-treated, and lattice diffusion-treated stones. Whilst, fracture-filled, cavity-filled, or dyed material should only be cleaned with a damp cloth.

If you have ever had any doubts about how to choose your rubies, this is what you should be looking for:  


The finest ruby has a pure, vibrant red to slightly purplish red color. The ruby moves down in quality when the color becomes too orangy or more purplish. High-quality rubies have vivid colour saturation. 



Inclusion-free rubies are rare and their value depends on how visible the inclusions are. Visible inclusions that reduce transparency or brightness lower a ruby’s value dramatically.  



The cut and proportion of rubies on the market depend on different factors and their crystal shape dictates their suitability for certain cuts. The flat tabular hexagonal shape is the most common one.  


Carat Weight

The price per carat goes up significantly for ruby as it increases in size, even if fine-quality rubies over one carat are very rare.
