5.35 CARAT NATURAL UNTREATED COLOMBIAN EMERALD AND DIAMOND RING


Centring on a cushion-shaped emerald weighing 5.35 carats, embellished with marquise-shaped diamonds and circular-cut emeralds, accented by brilliant-cut diamonds extending to the shank, the diamonds totalling approximately 2.30 carats, mounted in 18 karat white gold. Ring size: 6 1/2

Gübelin report numbered 17091013, 16 September 2017, stating the emerald is 5.35 carats, natural, green colour, Colombian origin, no indications of clarity enhancement; along with an information sheet to report no. 17091013, stating that 'the developing emerald experiences significant mechanical strain, resulting in fissures and fractures throughout the stone. In most cases, this process lowers the transparency of the stone, depending on the number and extent of the fractures. By filling these fissures and fractures with a foreign substance such as oil, resin or wax, the transparency of the emerald can be enhanced. At the time of analysis, the emerald described in the above did not show any indications of clarity enhancement.'
