Oval Ruby & Diamond Cluster Ring in Platinum

• 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.

• Hammer Price - At an auction the hammer price is the price achieved on the fall of the hammer. In most auction the buyers premium is then added to the hammer price to calculate the amount the purchaser must pay.
  
  For a seller, the vendor's commission and sometimes insurance, photography and lot charges are deducted from the hammer price to calculate the amount payable to the vendor.
  
  The hammer price is different from the auctioneer's estimate, the reserve and the bought-in price.
