1. A cutting element comprising:
- A. a cutting member comprising ultra-hard crystalline material;
B. a support body comprising a highly conductive low oxidizing metal selected from the group consisting of silver, gold, platinum, tungsten and rhodium; and
C. a cushion layer comprising a ceramic clay substantially between the ultra-hard crystalline material and the support body.

-
A. a support body comprising a metal selected from the group substantially consisting of silver, gold, platinum, tungsten and rhodium; B. a cutting element comprising an ultra-hard crystalline material selected from the group consisting of diamond, cubic zirconium and carborundum placed within said support body wherein the cutting element is oriented in said support body so that a major crystalline axis of said cutting element is substantially centered on one surface of said support body; C. a coating on the surface of said cutting element substantially comprising a silicate glaze; D. a cushion layer substantially between said silicate layer and the support body comprising a ceramic clay; and E. an abrasion resistive layer on said support body comprised substantially of rhodium. - View Dependent Claims (15)
