What’s the single crystal diamond plates
HPHT single crystal diamond are synthetic diamonds produced by high pressure high temperature synthesis under tightly controlled growth conditions. More Super Hard mainly produce industrial-grade single crystal synthetic diamond plate. The shapes of mcd diamond plates include round shape, square shape, rectangle and hexangle shapes,etc.
HPHT single crystal diamond plates are divided into Grade A, Grade B and Grade C
Grade A: with precise laser cut edge, no missing angle, clean crystal, without any inclusions under the microscope
Grade B: a lack of angle,can see the minimal inclusions under the microscope
Grade C: a lack of angle, can see the visible inclusions and scrap inside under the lights
