How does an unpolished shungite pendant differ from a polished one? — Unpolished Pearl Pendant, 20 mm

The product name states that the “Pärl” pendant is unpolished, size 20 mm. This means the surface of the stone has not been polished; such a surface is usually matt and keeps the natural texture, while a polished one is smooth and glossy (general information, not a manufacturer's instruction). The product card describes no other differences (colour, durability, care), and the manufacturer makes no comparison with polished pendants.

What is supplied with it (a cord or a chain) and its length are not stated on the product card — check this before buying.
