1) The name “ruby” comes from the Latin word “ruber” meaning “red”
Early records also see ruby called “Ratnaraj” in Sanskrit, meaning “King of Gems”. Historically rubies were worn by soldiers to protect them in battle, and in medieval Europe this red gem was associated with the qualities of passion, health, success and wisdom.

2) Spinels were mistaken for rubies until the 18th century
The red variety of spinel was assumed to be ruby until scientists discovered it was a completely different gemstone in the late 18th century. One of the most famous examples of this mistaken identity is the “The Black Prince’s Ruby”, the 170-carat irregular spinel bead that has been in the British Royal Family’s possession since 1367. Today this gem can be seen in the Imperial State Crown alongside other famous stones such as the huge 317-carat Cullinan II diamond.

The Imperial State Crown was originally made for Queen Victoria's coronation in 1838. It incorporates many gemstones, including the diamond known as the Second Star of Africa, the Black Prince's Ruby, the Stuart Sapphire, St Edward's Sapphire and Queen Elizabeth's Pearls.
3) They’re a favourite Royal gem
As demonstrated by Queen Elizabeth II’s Burmese Ruby Tiara. The piece was made in 1973 by House of Garrard and combines 100 Burmese rubies the Queen was gifted on her wedding day with diamonds taken from another dismantled tiara.

The Queen’s Burmese Ruby Tiara is one of the most symbolic and personal pieces created for Her Royal Highness by the House of Garrard. The 96 rubies mounted in the tiara were originally given to the queen as a wedding gift from the people of Burma, intended as a symbol of protection against illness and evil. #Garrard #royalfamily #heritage #ruby #queenelizabethii
4) Ruby and sapphire are the same stone
Well, pretty much. Both are the mineral Corundum and have identical chemical properties apart from their colour. Sapphires come in a rainbow of colours (as well as their traditional blue, these can include yellow, green and pink) except red - which wins the ruby title.

5) The first rubies were discovered in Burma
These gems can be traced back to 600AD in Burma (or Myanmar), still widely recognised as the superlative source of fine rubies today due to their ability to fluorescence and emit an intense “glow” in sunlight. Today other important sources of rubies include Vietnam, Mozambique and Tanzania.

6) Top quality rubies are called “Pigeon Blood”
The name comes from the pure red colour found only in rubies of exceptional transparency with no other overtones such as pink, brown or purple.

7) They can be very expensive
Ruby is the only coloured gemstone to break the $1million per carat mark. This record was set by the Sunrise Ruby, a 25.59-carat stone set into a ring by Cartier, which sold at Sotheby’s Geneva for $30,335,698 - or $1,185,451 per carat - in 2015. Phew.

8) They’re the birthstone for July
But don't worry if your birthday falls in a different month - rubies are also traditionally gifted to mark a 40th wedding anniversary.

9) Most rubies on the market are treated
Treatment improves the colour and clarity of gemstones. Less than 10% of gem quality rubies are unheated or untreated, which makes these particular stones very rare indeed.
Who'd have thought!
