If you think that buying brown diamonds can be a challenge,
you have not tried to pick out the perfect opal. Insiders throw around terms
like “crystal” or “black” when the stone does not look like it. To equip you
for a confident buying decision, we are answering your opal related questions.
What is a black opal?
The black opal is the Corvette of the gem’s class. It is
rare, valuable and features some telltale displays that heighten the
desirability of the stones. For example, the more red tints you see in a black
opal, the more expensive it is. Another favorite is the blue and green
combination of hues. Since the color play displays against a black backdrop, it
is far more dramatic than any other type of opal you may see.
Case in point is this unique black opal ring with flashes showing green, blue, orange and yellow. Artisans placed the oval cabochon-cut stone, which weighs in at 6.50cts, in a
platinum setting. Dating back to the 1920s, you notice the beginnings of the
Art Deco design elements. Enjoy sparkle coming from six emerald-cut diamonds
with a combined weight of .40cts.
Why is a boulder opal so much less expensive?
Well known for its darker colors, the boulder opal is a gem
that formed along with ground stones. Because these stones make up part of the
gem, its value is considerably less than that of its black counterpart. (Ask to
see the stone’s certificate to ensure that you get more opal than stone
backing.) That said, its darker colors hold great appeal for the right
collector.
This boulder opal enhancer in a 14k yellow gold setting from our workshop is an excellent
example. The stone is untreated and shows off flashes of orange, yellow and
green alongside the brown backing. It measures 21.85mm by 14.25mm. It is
gorgeous.
How do I choose a crystal opal?
Unlike black or boulder opals that denote specific types of
the gem, a crystal version of the stone can be found in either camp. The term
simply refers to a stone that has translucent qualities. Transparency has the
potential to add value to an opal.
For example, this 1940s semi-black, crystal opal enhancer pendant combines multiple desirable traits. The
pear-shaped stone’s luster appeals to the eye alongside the green, red and blue
flashes. Artisans enhanced the look of the 14k yellow gold jewel with the
addition of seven round diamonds that weigh a combined .21cts.
