Gemstones are a part of many ancient cultures, often considered to be a talisman or symbol of good luck or fortune. Different gems are said to have different properties, and for thousands of years, they have been made into rings, bracelets, amulets, brooches and pendants to capture their magic. A popular theory is that gemstones contain vibrational energy. By placing gemstones within a person's aura it is possible to change the vibrations of that aura.
