賣家描述
Natural Emerald – 4.16 ct – Ural Russia – Insignificant Oil – GRS Switzerland Certified – Octagonal Cut
Description
Royal Antwerp Gem – Antwerp, Belgium
An exceptional natural emerald weighing 4.16 carats, originating from the historic Ural Mountains of Russia, accompanied by an official gemstone report from the prestigious Swiss laboratory GRS (GemResearch Swisslab).
This remarkable gemstone displays a distinctive pastel bluish-green colour, offering a delicate and elegant appearance that distinguishes it from traditional deeper green emeralds.
Expertly fashioned into a classic octagonal shape with a step-cut faceting arrangement, the emerald features attractive proportions and a refined geometric appearance.
One of the most important characteristics of this gemstone is its exceptionally low level of clarity enhancement, classified by GRS as CE(O): Insignificant.
This classification indicates only insignificant oil enhancement, an especially desirable characteristic for a natural emerald.
The gemstone’s certified Russian Ural origin, substantial carat weight, distinctive pastel bluish-green colour and minimal clarity enhancement make it an appealing choice for collectors and bespoke fine jewellery creations.
