Diamond color determines the level of color present in the diamond, or in fact, the absence of color in a diamond. Grades D-F are colorless and icy white and carry the highest price point. Grades G-J are nearly colorless, which means that the diamonds will exhibit an indistinguishable tint of yellow or brown. The color grade system goes all the ...
2021-11-15 · To relate the mechanism of graphitization to the diamond-surface orientation in a systematic manner, in this study we focus on single-crystal diamond (SCD) in its three basic crystallographic orientations – (111), (110) and (100) – as catalytically graphitized by sputtered Ni at elevated temperatures.

Diamond merchants use the Rapaport price list to calculate the price of diamonds. This list is divided into different price grids according to the carat of the diamond, for example there is a price list for 0.40 to 0.49 carat and another one for 0.50 to 0.59 carat. The carat price increases with every change of grid.

2015-5-6 · Growth of single-crystal diamond by chemical vapor deposition. A direct method for growing large single-crystal diamonds is the epitaxial growth of seed crystal faces, resulting in the enlargement of all crystal dimensions. As a crystal grows homoepitaxially, all its faces, including the lateral ones, become extended.
