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