Today is National Jewel Day, so to celebrate here are ten facts about Sapphires:
The word sapphire is derived from the Latin word sapphirus, which which originally referred to lapis lazuli.
Sapphire ranks as a 9 on the Mohs scale of hardness, meaning it is the second hardest material known to man. Only Diamond is harder. Hence some of sapphire’s industrial uses: lenses and screens for Watches, and Bar code scanners.
Sapphire is a variety of the mineral corundum, consisting of aluminium oxide with trace amounts of elements such as Iron, titanium, cobalt, Lead, chromium, vanadium, magnesium, boron, and Silicon. They’re actually made from the same stuff as Rubies.
Although we associate sapphire with the colour Blue, depending on the trace elements they can come in a range of hues including clear, Pink, Orange and even Black. Sapphires in colours other than blue are called "fancy" sapphires. A padparadscha is a pinkish orange sapphire which is especially rare and valuable.
Sapphire is the birthstone for people born in September. It also represents both the 5th and 45th wedding anniversaries, and a sapphire jubilee occurs after 65 years. In 2017 Queen Elizabeth II marked the sapphire jubilee of her accession to the throne.
Staying with royalty for a moment, in 1981, Prince Charles presented Lady Diana Spencer with an engagement ring featuring a diamond-encrusted oval royal blue sapphire weighing 12 carats. This became the most famous blue sapphire in the world. Sapphires were also a popular choice for Victorian engagement rings, especially surrounded by diamonds in floral designs.
Sapphires can withstand temperatures as high as 1700-1900° Celsius without melting. Exposing them to temperatures this high is part of the process of enhancing their beauty.
The sapphire has been the official state gem of Queensland, Australia since August 1985.
Sapphires can be found all over the world, but Sri Lanka is the best producer.
Now for the folklore and superstitions. Hindus believe that wearing sapphire makes the planet Saturn (Shani) favourable towards the wearer; an old Italian superstition claimed that sapphires were good for eye problems and melancholy. Mary Queen of Scots owned a medicinal sapphire worn as a pendant to rub on her sore eyes. Many believe that sapphires can improve your ability to concentrate, be more creative, think more clearly, and be happier. It is also said to help eradicate unfavourable feelings and ideas.
