Where to buy?
For Benitoite or Peridot check what Amazon has to offer. You'll usually find quite a selection from many different vendors. Worth a check. For other high quality gemstones (Rubies, Saphhires, Emeralds) and especially Diamonds, I highly recommend JamesAllen.
Face-up Size
All things being equal, Benitoite will face-up smaller than Peridot for a given
carat weight, because it has higher specific gravity
(3.65 vs. 3.35 - this means it's "heavier" compared to Peridot 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.
