Black Opal and Diamond Cluster Studs in Rose Gold

• Closed Back in Jewellery - A closed back setting in jewellery refers to a type of setting where the back of the stone is not visible. The stone is typically set in a metal bezel or cup that covers the back and sides of the stone. This type of setting is commonly used for opaque or dark-colored stones, as it helps to improve the stone's overall appearance by hiding any inclusions or blemishes that may be present on the back of the stone.
  
  Closed back settings are also used to protect the back of the stone from damage or to prevent it from falling out of the setting. This type of setting can be found in a wide range of jewellery styles, including rings, earrings, and pendants, and can be made from a variety of metals, including gold, silver, and platinum.
  
  

• Bezel - On a clock or watch, the bezel is the metal frame into which the watch or clock glass is fitted. In clocks, the bezel may include a hinge and a flange, in effect a door to the face of the clock. In jewellery the bezel is a band of metal with a projecting lip that holds the gemstone in its setting.
• 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.
