How many facets?
-
The standard number of facets of a Radiant Shape Diamond is generally 70 facets
(25 on the crown, 8 on the girdle & 37 on the pavilion).
What does it look like?
-
The Radiant Cut Diamond is a straight-edged rectangular or square stone with
cut corners. The truncated corners help to minimize chipping.
-
The radiant cut is a patented name & cut also know as a cut-cornered,
rectangular (or square) modified brilliant on GIA grading reports.
-
Generally if you are looking for a square cut, a Radiant Shape's length to
width ratio is approximately 1.0 to 1.1:1. For a more rectangular shape, look
for a ratio 1.11 to 1.5:1
What works best for Radiant Cut?
-
Radiant cuts are principally used for important centre stones, but also for
pendants.
-
Popular before the princess shape was around, the radiant has more facets than
a princess, but has the corners trimmed like the emerald shape. This shapes
popularity has now been surpassed by that of the Princess shape.
The Radiant can either be cut as a square or rectangle. The Radiant has a strong
look with a unique type sparkle, differing from Emerald and Princess Cuts.
Trimmed corners are the signature of this fancy-shaped diamond, and they also
make the diamond very versatile. A radiant-cut looks equally beautiful set with
either baguette or round side-diamonds. When choosing a colour grade, consider
that while the price of a lower colour fancy-shaped diamond is exceptional,
colour may be slightly visible in its corners.
The Quality Diamonds Basic Grading Chart has been used to

this simplified method to assist customers who prefer not to delve into very
specific details, after all, if you are not completely satisfied with your
purchase, you have the right to a full refund, or to exchange your diamond for
