The diamond is a symbol of purity. It bonds relationships, bringing love and clarity into partnership. Also, an amplifier of energy. Another stone that doesn't need recharging. It increases the energy of whatever it comes in contact with and is very effective when used with other crystals.
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.
