Sri Yantra has been around for more than 12,000 years. The design of the Sri Yantra is based on the number 1.1618, also known as the Golden Proportion. It contains nine triangles. Four of them point upward to represent the power of the universe and all that is beyond our quotidian sense perceptions. Yantras are also mystical representations of deities that can serve as protective shields against negative energies. This sacred geometry Sri Yantra ring is made of solid hypoallergenic stainless steel and has a high polish finish. The Golden Proportion design measures 22mm wide at the center by 3mm wide at the band back and is an adjustable band. This sacred geometry Sri Yantra ring is currently available in sizes 7.5, 8, 8.5, 9, and 9.5. A gift box is included with the purchase.
