such as the crystal type, shape, the cutter decisions, and abilities.

Preform with acceptable shape (must have enough depth %) and eye clean clarity (or better)
\
Ideal natural rough shape piece (one with good depth % and minor surface issues ) with eye clean clarity (or better)
*at this grade-potential total yield from the rough weight at acceptable shape,and with eye clean clarity, after preforming
and without trimming -could be 50% or higher
AAA\VVS
eye clean clarity (or better) with some surface issues & \or not Ideal shape,
may require trimming to maximize yield.

should be 20% or higher
