What is it?
Bracelet Bianchi is a really rare range of semi-precious black shungite stone.
This rock is extracted in one land deposit, situated in Shandong Province (China). Since a massive meteorite fell in this region 63 million decades ago, the stone has a meteoric source.
Industrial rock mining began in 2009, but on account of the popularity of this stone, black shungite reserves are depleted. Quite soon, the rock can be bought second hand.
