Do you know how this type of Shungite got its name?
Petrovsky Shungite is named after Peter the Great, Russian Tsar of all Russia from 1682. He was the first Emperor of all Russia from 1721 until his death in 1725. He reigned jointly with his half-brother Ivan V until 1696. From this year, Peter was an absolute monarch who remained the ultimate authority. You can read more here.
Peter was the founder of the city of Petrozavodsk in Karelia, Russia, where Shungite deposits are found. Petrovsky Shungite has a higher carbon content than regular Shungite, which gives it a deep grey colour and a unique lustre.
This is a dark grey and not as shiny as Elite. In fact most Petrovsky is not shiny at all. It is also EXTREMELY rare now to be found online and is not sold very often, other than in bracelet form. Some websites are claiming that they are selling Petrovsky shapes. I would be very careful about this. Firstly, it is rare for Petrovsky shapes to be in the market. Secondly, it is not that much cheaper than Elite, so if you are offered Petrovsky, at a reasonable price, you can be pretty sure it is not Petrovsky, probably the Regular Black Shungite.
