The ring produced will have a top flat surface 23mm across, the widest part of ring is 29mm and 18mm from top of ring to top of finger hole. Dimensions may vary slightly based on ring size.

These molds will produce a glass-smooth glossy surface.
I use platinum cured silicone: - 20 Shore Hardness A - Semi clear - Temp range -50c to +205c (-122f to +405f) - Will not become brittle or break-down over time, unlike tin cured silicone molds - Can be used for molding Epoxy, Resin, Soap, wax
All my molds are first degassed in a vacuum chamber, then cured under 55 psi in a pressure chamber resulting in a flawless mold surface.
