Ammolite ring in sterling silver. “Ammolite” is the trade name referring to gems cut from fossilized ammonite, an extinct group of marine invertebrate, also collected as whole specimens. Ammolite popularity has grown over the past decade, since renowned feng shui master Edward Kui Ming Li began extolling its virtues to his followers. Said to promote the flow of “chi” throughout the body, enhance well-being, and reduce toxins, Ammolite can exhibit up to seven colors—each said to bring a certain benefit, such as wealth, wisdom, health, growth, or energy. Feng shui practitioners call it the “seven-color prosperity stone.” Gem is approximately 1 inch long.
