Wholesale Black tourmaline rough, box with 5 kilograms

Sealed 5-kilogram box of rough black tourmaline This box contains a selection of between 26 and 34 pieces of rough black tourmaline, with a minimum total net weight of 5 kilograms. Piece sizes range from approximately 100 grams to 500 grams each, although some may be larger or smaller. The box in which the pieces are supplied measures 24 cm x 22 cm x 9 cm and comes sealed, which means you cannot choose the pieces inside. Although the pieces do not have a cut base, several of them may stand upright. It is normal for the rough black tourmaline pieces to shed some dust or small fragments, which indicates they have not been treated with resin for stabilization and are 100% natural. If you want a shinier black appearance on the pieces, it is recommended to apply a little mineral oil, such as machine oil or body oil, using a cloth. The photos shown are examples of what may be found in the box; the pieces sent will be similar to those pictured. Origin: Brazil.
