Swarovski Crystals are not actually crystals in the sense of natural stones. They are fine crystal glass made by Swarovski in Austria. Thus they have the energies of glass as well as color energies related to their color. They also bring positive energy, hope, joy, good luck, and diffuse negative energy.
Quartz is the most powerful healing stone. It absorbs, releases, and regulates energy and is excellent for unblocking it.
