Unrivaled Tungsten Mass
Hand-finished from solid Tungsten Carbide—Earth’s hardest jewelry metal—giving the ring an incredible weight, hypoallergenic safety, and a permanent mirror finish that never scratches or tarnishes.
Dual Natural Inlays
Features double inlay tracks merging iridescent natural abalone shell with shimmering crushed blue opal, creating a dynamic ocean-like depth effect under ambient light.
Broad-Band Anatomical Restriction
Spreading the contact surface across a 20 mm distance distributes pressure evenly behind the corona. This broader hold traps blood volume in the glans for maximum engorgement and firmness while preventing localized pinching or slipping during movement.
Extended ErgoFit® Interior Geometry
Contoured with an extended internal blend radius to glide effortlessly over sensitive tissue and sit comfortably all day.
Oceanic Stacking Symmetry
Designed to pair with our flagship Proteus Cock Ring for a balanced, double-inlay stacked look.
Zero Sizing Guesswork: Try Our 3D-Printed Sizing Rings
Solid Tungsten Carbide cannot be resized, making precision fitting essential for all-day comfort.
To guarantee complete sizing confidence, select the "Ring + FREE Sizing Rings" option. We will first ship you a 3D-printed sizing kit that precisely mirrors the 20 mm width, internal diameter, and ErgoFit® curvature of the final tungsten piece. Test the sizing rings at home to confirm your ideal fit before we ship your finished solid tungsten and opal ring.
