Actual sizes of 1ct Andesine Emerald (7.3×5.41mm, Dark Red) and 1ct Quartz Pear (6.86×6.86mm, Orange) as they would appear on a ring and finger. Adjust the ring and finger size to get an idea of how these gemstones would look on your finger.

Where to buy?

For Andesine or Quartz 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, 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 "slightlyheavier" compared to Quartz 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.
