The Ruby gemstone is a type of mineral called corundum; the blood red or pink colour is caused by Chromium. Rubies have a Mohs Scale hardness of 9.0 making them one of the hardest coloured gemstones. The Ruby is the most expensive per carat coloured gemstone and is an important part of the gemstone market.

Compared to other major gemstones like emeralds, sapphires and diamonds, it is harder to find large sized rubies which makes them highly priced. The largest Ruby gemstone found so far was called the Liberty Bell Ruby and weighed 1.8 kilograms. 

A gemstone with a passionate history

The Ruby gemstone is one of the most written about in history – it is mentioned four times in the bible – and has historically been linked to wisdom, beauty, safety, peace and to make its wearer invincible in battle. The name of the gemstone comes from the Latin word ‘ruber’ which means red. Rubies were one of the most popular gemstones among European royalty from the Middle Ages, when the stones were thought to bring wealth, good health and luck in love, to its wearer.

Rubies were believed to protect a person against wicked thoughts, disputes and lustiness. The Ruby gemstone is also thought to be able to improve the blood circulation in your body. Rubies are not only revered in the jewelry market but they are also considered important for their astrological properties as the birthstone for the month of July

Where Ruby gemstones come from

Rubies that are mined in Burma are considered to be the best in the world as they have a pigeon-blood red colour. Other counties where rubies are mined include Nepal, Thailand, Vietnam, Taiwan, Pakistan, Afghanistan, and East Africa. They are also mined in numerous locations across the United States such as Arkansas, Arizona, Oregon, Nevada, Idaho as well as in Franklin, North Carolina.  

While most Rubies are red in colour, they can also be pink. A Ruby gemstone with a darker red colour is highly valued due to their rarity. 

How to choose the best Ruby gemstone

Here are some tips that will help you to choose the best Ruby for your personal collection. 

  • The pigeon-blood red Ruby is the best shade of Ruby gemstone and therefore you should always choose the darkest and brightest Ruby you can afford. 
  • All rubies have inclusions but the stones that have fewer visible inclusions are typically the most expensive. The clarity of the Ruby gemstone is definitely a major determining factor when it comes to its price. 
  • The cut of the Ruby is also important when it comes to determining the price of Rubies. Round cut Rubies are by far the most expensive type of cut for this gemstone.
