A key unlocks many doors. It's an ancient symbol that represents knowledge and discovery. In ancient Egypt, the Ankh symbolized the key of life with its key-like shape and ability to unlock life's mysteries. A key represents the discovery of a treasure close at hand, be it of the heart or soul. All of the stones used in the Key of Life Collection are genuine precious and semi-precious gemstones chosen for the special properties for which they are known. Each Key of Life is defined by its particular combination of gems. The stones, singularly and together, bring life and individuality to each piece.
