A cabochon sapphire and diamond mounted bracelet (FS19/152)
This cabochon sapphire and diamond mounted bracelet (FS19/152) is being auctioned in the Fine Jewellery Auction that is part of our quarterly fine sale being held in Exeter in Devon on 3rd July 2013 with a pre-sale estimate of £800-£1,200.
The sapphires within this bracelet have been shaped and polished as opposed to being faceted, resulting in a convex top with a flat bottom. This type of cut is known as 'cabochon' can also be applied to rubies, emeralds and garnets.
The sapphire is part of the 'corundum' gem variety, the other two being ruby and padparadshca. Sapphires can be found in many colours including grey and black, the most well-known being blue. Fancy sapphire colours such as pink sapphires are popular at auction and deepen in colour as the quantity of chronium increases. The deeper the pink, the higher their value.
