Jewellery and Rings

Q: I have a question regarding using/wearing stones in jewellery. I know that stones like kyanite and lapis lazuli are often used by people because they believe that they have certain metaphysical properties. I've recently come into quite a few stones (quartz crystal, malachite, kyanite, etc.) that have been passed from person to person, but the original purchaser bought them because of the metaphysical properties that they believed them to have. I simply think that they're beautiful rocks and creations of Allah Ta'ala and have no intentions of relying on them for anything. Is it permissible for me to wear them as jewellery? Would that be a form of shirk? Diamonds and sapphires are believed to have certain properties as well; should we just avoid all stones?
