The Essential 7C's
Every diamond has its own story, and every lady her own style.
At this point it should be noted that the shape of a diamond
can also be referred to as its “cut”, like a round or princess cut.
However, this should not be confused with the more commonly used term of
diamond cut, which describes how well the diamond has been polished
from the raw material (see section on diamond cut).

4. History & Background
The first Radiant cut was designed by Henry Grossbard of the
Radiant Cut Diamond Company (RCDC) in 1977. Prior to this invention, all
diamonds with square or step-cut edges appeared less brilliant.
Grossbard invented a hybrid cutting style that revolutionised
the industry's perceptions towards square or rectangular stones as he
managed to create a step-cut diamond that possessed equal brilliance to
triangular-faceted diamonds such as the oval and pear.
The Radiant is also the first cut to have a brilliant-facet
pattern applied to both the crown & pavilion. RCDC launched the
Original Radiant Cut diamond brand in 2002.
