Big and bold 14mm wide, beautifully textured meditation ring, with 4mm wide flat spinning band, and a vibrant green 4mm lab grown Emerald. Fiddle, fidget, spinner - no matter what you call it these rings are incredibly comfortable, and maybe just a little addictive as you spin your way to calm. Emeralds are a birthstone for May, linked to the heart chakra. They are thought to promote abundance and compassion. Size 8.25
