September - Sapphire

Sapphire, a variety of the mineral corundum, is the traditional gemstone to represent the birthstone of the month of September. The word sapphire is said to originate from Latin and Greek words both meaning blue, and this is logical considering blue is the most common shade of sapphire.  


Sapphire is more often than not blue in colour although there are varieties which can occur in yellow, green, orange and purple colours. 

Interestingly, Ruby is also a variety of the mineral corundum and all non-red varieties of corundum are considered sapphires. 


The benefits of wearing sapphire are very often linked to astrology and in particular, the planet Saturn.  Sapphire is regularly referred to as the fastest acting gemstones and is linked with love and fidelity as well as positive and speedy resolution of legal matters and this is perhaps why it was historically worn when signing treaties.  


Sapphire is another gemstone with links back for thousands of years.  It has even been stated in many sources that the stone used to record the 10 commandments was sapphire.  

Sapphire is also frequently associated with Royalty and, particularly for us British, a memorable piece is the engagement ring worn by Princess Diana for her marriage to Prince Charles.  This ring is now famously worn by the Duchess of Cambridge, Kate Middleton, given to her by Prince William, Duke of Cambridge.  

The crown jewels feature two very famous sapphires, the Stuart Sapphire and the St Edward’s Sapphire, in very prominent positions on the imperial state crown.

Another world famous sapphire is known as The Star Of Asia.  This is a cabochon cut star sapphire weighing a mighty 330carats and is on display at the Smithsonian National Museum of Natural History

The most expensive sapphire known to date was part of a sapphire and diamond ring sold at auction in New York in 2014.  The 28 carat Kashmir sapphire sold for more than $5million.



Kashmir, a region in India, is known to produce sapphire of deep blue colour but these are also quite scarce and therefore very sought after.  Cambodia is also known to produce some very fine sapphire.  

Sri Lanka is also another source of sapphire, which are more abundant but also much paler in colour than the sought after Kashmir sapphire. 

There are several other areas in the world where sapphire is found, such as Columbia, Montana and North Carolina (USA), Brazil and Australia, which often produces sapphire of a variety of blue, green and yellow.
