Diamond-like gem

12 june 2023
One of the most beautiful, but forgotten for many years, Ural gems is a sparkling demantoid. Discovered at the Demidov mines in the middle of the 19th century, it managed to dislodge His Majesty Diamond from the jewelry throne in the heyday of Russian Art Nouveau at the beginning of the 20th century, but went into the shadows after the the Russian Bolshevik Revolution for many years.
Many stories and legends are associated with demantoid (or chrysolite, as it has been mistakenly called for a long time) in the Urals. It is enough just to read the famous tales of Pavel Bazhov about the Silver Hoof or the Fire-Fairy.
We will tell a short story about how demantoid first entered the global jewelry market. In 1891, a cousin came to Yekaterinburg to visit the legendary Ural local historian, Swiss by birth, Onesim Clair. The brother's name is Joseph Kunz and, by an incredible coincidence, he is a gemologist at Tiffany & Co. Kunz fell in love with the sparkling green stones so much that, as the newspapers later wrote, “he bought all the demantoids available on the market for 50 thousand rubles, although he would have bought them for a larger amount.” Soon, apple-green demantoids with a golden sparkle (mined, by the way, at the Poldnevsky deposit) will sparkle in Tiffany&Co jewelry.
The Poldnevskoy Demantoid company was founded in 2013. Today, the enterprise is engaged in the extraction and cutting of demantoids, being the official supplier of green garnets on an industrial scale.
The Poldnevskoy Demantoid company has an exclusive license to develop the famous Poldnevskoye demantoid deposit.
Poldnevsky demantoids are sold at gemological and jewelry auctions, getting into the collections of famous brands.
So, the beautiful necklace with demantoids of the Blue Book "Colors of Nature" 2021 series from Tiffany is assembled from Ural demantoids of a characteristic apple-green hue with a golden tint.
The Poldnevsky Demantoid company wants to restore historical justice and return to the green grenade its undeservedly faded glory.
We are sure that the Urals can and should be known to the whole world precisely as the birthplace of one of the most beautiful stones in the world.
