This comforter was created specifically to be used in with the BioMat to increase the quantum benefits of the BioMat. The comforter has 48 amethyst stones that are 1.2 inches in diameter sewn between the fabrics on the outside. Each stone is polished for maximum effect and to provide a softer feel. The fabric itself is a mixture of jade powder and the silver side is microfiber. The jade compliments the healing power of the amethyst stones.
