Sapphire is the beautiful birthstone of September and we simply love this gemstone! The name sapphire comes from the Greek word ‘sapheiros’ meaning blue. This is not the only colour they come in. From pink to yellow to colour change, sapphires come in an array of alluring colours and sizes.
The history of the sapphire is full of excitement. Adorning the fingers of kings and holy men alike. In ancient civilisation, monarchs believed sapphires would protect the wearer from envy and harm, during the Middle Ages, religious men wore sapphires to symbolise heaven and throughout history sapphires have been a powerful talisman in protecting against enemies and evil spirits. Sapphires feature in everything from Georgian to Modernist designs and the gemstone has held its popularity throughout the centuries.
Some of the many different types of sapphires include the Ceylon sapphire. Ceylon is one of the most famous sapphire producing regions and gemstones have been found here as early as 2nd century BC. Many famous sapphires have come from this region, including the 563 carat Star of India and the 423 carat Logan Sapphire. Recognisable for their vivid colour, they are much brighter and lighter than sapphires from Australia and Thailand, and can command exceptionally high prices.
Coloured sapphires are created as a result of the chemical structure holding different trace minerals. Blue sapphires show both titanium, chromium is responsible for pink sapphire colour and iron impurities show the yellow sapphire colour. Another magnificent effect is the star sapphire. This effect due to optical phenomenon called asterism, deriving from the Latin word ‘astrum’ meaning star. Asterism is created by needle-like inclusions of the mineral rutile.
