18ct White Gold Sapphire and Diamond Cluster Ring

• Brilliant Cut - In their naturally occuring state diamonds have little life or sparkle and for many centuries were simply cut in half and worn in amulets. Invented at the end of the 17th century by a Venetian diamond cutter, a "brilliant cut" diamond has 58 facets arranged in a regular geometric relationship, with 33 above the crown and 25 below on the pavilion.
  
  The introduction of the brilliant cut increased the popularity of diamonds in jewellery as it was the first cut to reveal the fire of the diamond, with the light being internally reflected from one facet to another, and was superior to the previously used table cut and rose cut.Variants to the brilliant cut have emerged since the end of the 17th century, but the popularity of the original brilliant cut has continued to the present time, where it is still the most commonly found cut.

• Padparadscha Sapphires - A padparadscha sapphire is the name given to a sapphire that is found in Sri Lanka. Colour can range from a salmon with a pinkish hue to an orange hue. In the Sinhalese language padparadscha is the name given to the color of a Lotus blossom. Sapphires with similar characteristics have been found in Vietnam, Tanzania and Madagascar, but there is dispute in the jewellery trade as to whether these stones should be called padparadscha. At times padparadscha sapphires are known to have been heat treated to intensify their pink coloration.
