Face-up Size
All things being equal, Kyanite will face-up smaller than Emerald for a given
carat weight, because it has higher specific gravity
(3.68 vs. 2.7 - this means it's "heavier" compared to Emerald of the same size). Face-up size also depends heavily on the
proportions of the cut.
Face-up area is a measure of the size of the gem when viewed from above (as set in a ring). It tells you how big the gem is at the girdle plane.
