Jeremejevite Information
Jeremejevite is a rare mineral from the borate class and due to it’s scarceness is very rarely found in jewellery. Jeremejevite is a colourless, sky blue or pale yellow mineral and originates from the Erongo Region in Nambia. Jeremejevite is one of the gemstones that is highly sought after by mineral collectors and gem collectors alike.
Jeremejevite Origin
Jeremejevite is named after Pavel Vladimirovick Jeremejev, a Russian mineralogist and engineer, who first recognized the mineral. He first discovered Jeremejevite at Mt Soktuj in Russia however this locality only produced tiny Jeremejevite crystals that were only suitable for mineral collectors.
About Jeremejevite
Jeremejevite is hard, has no cleavage and is not brittle. This makes it a suitable gemstone for making jewellery with. However because of rarity of Jeremejevite, if something was to happen to a stone in a piece of jewelry, replacement would be near impossible. Jeremejevite is generally colorless, yellow or blueish in colour with faceted gemstones rarely found bigger than 1ct. Cut Jeremejevite gemstones that are clean and without inclusions are extremely rare to find and demand a high price. Interestingly, Jeremejevite is piezoelectric, meaning it will produce an electric current when it has mechanical force applied to it.
Where is Jeremejevite found?
There are only a hand full of locations known around the world where Jeremejevite is found, with Germany having six deposits. The best and most available deposits are found in Namibia, particularity in the Erongo Region. Other sources of Jeremejevite are the Pantahole Mine near Momeik, Myanmar (Burma) and a deposit near the Tadjik town of Chorugh (Khorog). In its natural form Jeremejevite grows in small obelisk shaped crystals.
