This "dazzling" New York Times bestseller about a flawed diamond with healing power that drives people to theft and murder is "an ingenious thriller" ( Daily News, New York).
Phillip Springer has been grading diamonds since he was eight years old. His eyes are as sharp as any magnifying glass, and he has used them to turn the family diamond business into a global concern. Besides their love of diamonds, the Springers have another interest: the occult, ESP, and the mystical power of gems. Phillip has never fully believed in such superstition, but a sudden death in his family forces him to contemplate things he thought impossible.

Among Phillip's inheritance is Stone 588, a flawed diamond that the family was never able to sell but that his sister claims has the power to heal-and the power to save Phillip's dying son. But before the boy can be cured, the stone is stolen. To save his child, Phillip must recover the rock, and he will kill to get it back.
