ideal diamond cut

The Choices in Diamond Cuts
by Amy Carrington

Diamonds are cut from stones in a wide variety of shapes know as cuts. Round diamond cuts are very popular for solitaire style rings and are ideal for stud type earrings.

PRINCESS

Another very common diamond cut for the large or center stone or in a solitaire style setting is the princess cut. EMERALD

Like the princess cut, the emerald shape requires a very clear diamond of high quality to preserve the clarity of the stone.

A less common cut is the asscher, which is a square version of the emerald cut.

PEAR

This diamond cut can add a slimming and elongating effect to the ring finger and is considered one of the classic diamond shapes. Heart shaped diamond cuts have long been a romantic favorite. Many of the colored diamonds look beautiful in the heart shape.

* Cleaving

* Sawing

* Faceting

The natural shape of the rough stone will also be a major factor in deciding how to cut the stone. Asymmetrical crystals such asmacles are used primarily for fancy cuts. Cubic shapes are ideal for a square Princess or Radiant cut. Sawing: A stone-cutting saw is a thin disk made of phosphor bronze. While the rough stone rotates on the diamond lathe a second diamond mounted on adop is pressed against it, rounding the rough diamond into a conical shape. Faceting: To facet a "Round Brilliant", a "blocker" or "lapper" will cut the first 18 main facets, then a "brillianteer" will cut and polish the remaining 40 facets.
