The Raw Crystal Rings are all made of very delicate, raw and at times porous stones. Due to their nature, they are fragile and therefore needs to be handle carefully. We recommend wearing the rings in stillness, such as during meditation and keep them in their box when not in use. We cannot offer guarantee on the raw crystal, other than the ring itself, if not handled with care. Shall you have any concerns regarding your Raw Crystal Rings, don't hesitate to reach us at info@sjalskarlek.com.
