Diamond symmetry

There are very few diamonds to be found with the perfect symmetry. When polishing a diamond, the main aim is to obtain the best possible proportion, symmetry of a stone being less important.

There are two more purposes ,which cutters try to achieve when polishing a rough diamond: to avoid inclusions and to safe as much weight as possible. This causes the diamond to have imperfect symmetry. The polished gemstone may have deviations in girdle thickness, tilting of table, culet off centering of the table and slightly oval shape.

According to GIA report, symmetry is graded as Excellent, Very Good, Good, Fair or Poor. However, it is difficult to distinguish between diamonds with Excellent and Good symmetry.

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.
