18K Gold 12ct No Oil Russian Emerald Ring, Crown Design Ring
Located in Hong Kong, HK
Russian emerlalds are hardly seen on the market nowadays due to being a private treasury of Tsar, followed by the state. However, Russia had been one of the biggest emerald producers since 1830's discovery in the Ural mountains so that world famous jewellery houses had purchased large deposits to make their magnificent jewellery works. Ural emeralds are outstanding in terms of their special, exceptional colour that distinguishes them from all the other emeralds widely sold on the market. It can be attributed to the chrome and iron inclusions, giving them vibrant hue and brilliant glow which capture your eyes. MOISEIKIN created this historically unique and fascinating non treated 12ct Emerald...

This impressive 1930s ring is supplied with an independent diamond grading report card for the diamonds, in addition to an emerald report card and certificate from the Gemmological Certification Services, London*. "Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics." Reference: The Connoisseur's Guide to Precious Gemstones, R.Wise, Brunswick House Press.
