18K Gold 12ct No Oil Russian Emerald Ring, Crown Design Ring
By MOISEIKIN
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...
