I'm cutting a 9 x 7 Aquamarine, emerald cut, about 2 - 2.50
cts., and I need a price. Can anyone give me an idea of what it
should sell for. Thanks.
With aqua, color is the first consideration: the bluer the
better, although I've noticed the current market is ever so
slightly beginning to prize the stone for its original
highly-desired greenish-blue color to distinguish it from the
sometimes garish (and cheap) blue topaz. Clarity is also
important because flawless material is pretty easily available,
even in fairly large sizes. Stones cut to proper angles are
naturally more valuable than those with windows. I looked at a
batch of aquas today with a price range from $30 to $400 per
carat retail. The lower end were pale greenish-blue with minor
flaw; stones in the $350-$400 range were loupe-clean strong
blues of excellent cut with no green (about the color of some of
the lighter London blue topazes I've seen.) You really need to
do a side-by-side comparison with other aquas to judge color: the
gradations can be subtle. I think the higher prices on those
stones were negotiable. The public just doesn't value aqua as
much as before blue topaz took over its color/market niche
(although aqua's still the only blue March birthstone). I
frequently see really nice stones at around $200/ct. retail.
Perhaps they would bring more in less competitive markets.
