HOW
TO CHOOSE
With boulder opal, choosing
a store, or "who you buy
from," is especially important.
Jewelry with a doublet or triplet
set in gold can be beautiful,
and their prices will seem quite
low compared to natural material.
It is important not to mistake
these for natural boulder opal
and base a purchase decision
on price alone.
The value of a boulder opal
lies in the strength of the
multi-colored flashes it displays.
After first confirming this,
compare a few stones in your
price range, considering the
shapes of the stones, the predominant
colors of the patches, and whether
they are full-face or partial-face.
Currently, market prices of
boulder opals are about one-fifth
the price of black opals of
similar beauty.
The value of a three-carat-size
boulder opal of jewelry quality
is approximately US $700 for
the stone alone. (2001) |
