Finishes Descriptions

Natural Cleft - a textured, natural finish both visually and to the touch. Achieved by splitting the stone along its cleave with a hammer and chisel.

Honed - an extremely smooth, eggshell finish. Achieved with the use of the diamonds.

Cascade - a fairly flat, uniform finish with subtle ripples and soft texture.
