This design appeared in a field in England on July, 18, 2018. The star tetrahedron is beautifully drawn here and represents the Merkaba, the vehicle of ascension.
This item is 1.44 inches in diameter and .20 inches thick. It is made by drawing the design on the stone in gold ink. Then adding colorful glitter and gluing a piece of glass to each side for protection. Finally a sterling silver bezel surrounds it, securing everything in place.
