Solid 18k gold wraps its way around this heavy duty tungsten carbide ring. Unlike most other inlay rings, the Tungsten Forever Saturn is brushed on the top for those who are looking for subtle perfection. Polished step edges add even more design and character to compliment the piece. The gold inlay is an industry high 0.7mm deep for long lasting inset strength, durability, and maximum value.
