Diamond Polish

Polish is also very important factor of a diamond grading. Poorly polished facets produce less brilliance and hamper the proper reflection and refraction processes.

A surface grain line is the most frequent polish defect. It occurs through the variations in a hardness of a diamond. Therefore, such defects can’t be avoided. The result is a grain polish line on a facet. Such grain lines are very frequent in pinky fancy colored diamonds. However, they may be only notable in reflected light.

Polish is thoroughly examined, facet by facet, with reflected light and magnification. Polish is graded as Excellent, Very Good, Good, Fair or Poor. Poor polish reduces the visual beauty of the diamond to a great extent. Therefore, one should choose a diamond according to the clarity grade.

Diamond Prices

Diamonds pricing is a complex and elaborate process that requires the consideration of many factors. Diamond prices are mainly determined by:

  • - The cost of mining and sorting the rough diamond.
  • - The cost of cutting the loose diamond.

However there are other costs necessary to manufacture the rough stone into a ready diamond. A very important stone may be certified and graded by an independent company in accordance with the ‘Four Cs’: carat, color, clarity, and cut.
