There is another incredible species of gemstones that encompasses the whole range of colours of the spectrum, clear through yellows, greens, mauves, blues, pinks, reds to blacks. The species is called Corundum and all the colours within it are now called Sapphires apart from the red variety, which is known as Ruby. Besides the beautiful variety of colour Sapphire holds, the gems have the other advantage of being second in hardness only to diamond. This particular property makes them ideal for use in an engagement ring, offering the alternative (or addition) of a favourite colour in a gemstone as equally precious as diamond. As colourful alternatives to diamond, Pink and Blue Sapphires have proven the most popular for engagement rings but bright yellows and greens are not to be underestimated as other alternatives.
Catherine has designed several inspiring pieces using this exquisite gemstone, with her ring designs punctuating the coloured gem with a sprinkle of bright white diamonds. A stunning style that stands the test of time, Catherine's pieces are the perfect gift for special occasions with Sapphire being the birthstone for September, and representative of the 65th wedding anniversary.
