Tsavorite Garnet and Diamond Cluster Ring

• Claw Set Jewellery - The description "claw set" in jewellery refers to a setting where the gemstone is held in place by metal prongs that resemble claws. These prongs are bent over the edges of the gemstone to secure it in the setting. This type of setting is commonly used for diamonds and other precious stones.
  
  

• Carat - A carat (abbreviated "ct") is a unit of measurement used to describe the weight of a diamond or other gemstone, and separately is a unit of measurement used to describe the weight of precious metals such as gold,.
  
  For gemstones, one carat is equal to 0.2 grams or 200 milligrams. The weight of a diamond is one of the Four Cs (along with cut, colour, and clarity) that are used to determine a diamond's value.
  
  It is important to note that a diamond's weight does not necessarily correspond to its size. A diamond's cut, which affects how well it reflects light, can make a diamond of a lower weight appear larger than a diamond of a higher weight. Additionally, the carat is not the only factor to determine the value of a diamond, other factors such as clarity, colour and cut are important too.
  
  In the gold industry, the purity of gold is measured in carats (abbreviated "ct"), with 24 karats being pure gold and lower carat numbers indicating a lower purity level. So, for example, 18 carat gold is 18/24 or 75% pure gold, and 12 carat gold is 12/24 or 50% pure gold.
• Garnet - A garnet is a mineral that is commonly used as a gemstone. It occurs in a wide range of colours, including red, pink, orange, green, yellow, and black. The most common and best known type of garnet is the red variety, which has a deep, rich colour and is often referred to as a "garnet red."
  
  Garnets have a long history of use as gemstones, and they have been prized for their beauty and durability for thousands of years. They are often used in jewellery, such as rings, necklaces, and earrings, and they are also sometimes used as a decorative element in other items, such as vases and goblets.
  
  Garnets are prized for their brilliance, durability, and resistance to scratching, making them a popular choice for use in jewellery. They are also valued for their hardness, which makes them well suited for use in abrasive applications, such as sandpaper and grinding wheels.
• Tsavorite - Tsavorite is a green coloured garnet, first discovered by a British geologist, Dr Campbell R. Bridges in 1961 in Zimbabwe while working for the United Kingdom Atomic Energy Authority.
  
  Unable to obtain a mining permit, he began prospecting in Tanzania and in 1967 made a second discovery of Tsavorite in northern Tanzania in 1967. Dr Bridges commenced mining the deposit, but the mine was nationalised by the government, so Dr Bridges moved to Kenya, where he made a third discovery of the mineral at the end of 1970.
  
  Tiffany & Co. began promoting the then unnamed mineral in 1973 in association with Dr. Campbell, and it was agreed it should be named Tsavorite, after the Tsavo National Park in Kenya, near to where it was mined.
  
  Dr Bridges died aged 71 in 2009 on his property in Tsavo National Park, Kenya, when he and his son were attacked by a mob in a dispute over mining rights.
