Natural druses of pyrite from argillite septarian concretions.
The rainbow color of the druses is a result that the pyrite crystals are covered by oxidation film.
The color is natural (we did not do any processing with the pyrite crystals).
The septarian concretions were cut into a slices (0.5 - 1.5 cm thickness) with the druses. Good for making jewelry.
For wholesale order. Price is for the 29 x 22 cm sheet with the pieces.
