Face-up Size
All things being equal, Emerald will face-up slightly smaller than Amethyst for a given
carat weight, because it has higher specific gravity
(2.7 vs. 2.65 - this means it's "slightly heavier" compared to Amethyst of the same size). Face-up size also depends heavily on the
proportions of the cut.
