Face-up Size
All things being equal, Sapphire will face-up smaller than Alexandrite for a given
carat weight, because it has higher specific gravity
(4 vs. 3.7 - this means it's "heavier" compared to Alexandrite 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.
