Patent ID: 8574535

Claim:
An as-synthesized high pressure high temperature (HPHT) synthetic single crystal diamond material having an as-synthesized aspect ratio of at least 1.5 on a notional surface S # , a longest dimension a # substantially aligned along either a <100> or <110> direction, and a seed face substantially parallel to either a {100} or {110} plane and substantially parallel to surface S # ; wherein the aspect ratio of the as-synthesized diamond crystal is defined as A # /B # wherein A # and B # define the notional surface S # in the as-synthesized high pressure high temperature (HPHT) synthetic single crystal diamond material substantially parallel to either the {100} or the {110} plane which is substantially parallel to the seed face of the as-synthesized single crystal diamond material, A # is the longest dimension of the as-synthesized high pressure high temperature (HPHT) synthetic single crystal diamond material within the surface S # substantially aligned along a <100> or <110> direction, and B # is the longest dimension of the as-synthesized high pressure high temperature (HPHT) synthetic single crystal diamond material orthogonal to A # within the surface S # , substantially aligned along a <100> or <110> direction; and wherein the longest dimension a # of the as-synthesized high pressure high temperature (HPHT) synthetic single crystal diamond material substantially parallel to the surface S # is at least 6 mm.
