A nice make for a Marquise
Cut is one where a 2:1 ratio exists, meaning the length is twice
the width. A 1.8:1 ratio is considered to be a fatter, heavier
shape and a 2.2:1, thinner and skinnier. (See Table and Depth
Percentage Formulas.)
A Bow Tie is the reflection of the
facets from the pavilion of a diamond which appears through
the table. It looks like a shadow or dark area in the shape
of a man's bow tie in the center of the Marquise. To eliminate
this effect, special pavilion facets are cut which the industry
calls the "French Culet". |
