What is a BLACK OPAL? | Opal Gemstone

(upbeat music) – This is Jill Maurer
with Your Jewelry Minute and today I’m answering the question, what is a black opal? And an opal generally has a body color. It has one main color, and then it has other
colors in it that flash. If the body color is
anything other than white, it’s known as a black opal even though the opal
could be sort of gray, green, blue, or black. All of those are known as a black opal. Black opals are highly
desired because usually it makes the colors in the
opal flash even brighter. It’s just a more dramatic look
than against the white opal. So, a lot of people like
a black opal better, and it is more expensive,
generally, than a white opal. About 90% of the opals
worldwide come from Australia, and the black opal is no exception. Most black opals do come from Australia. Now sometimes, we’ll take
just a sliver of an opal and we’ll back it. We’ll glue it to a backing, and that backing can be a dark stone. If we take a white opal and
glue it to a black stone, which is known as a
doublet, when you do that, the opal can appear to be
a black opal, but it isn’t. That is not classified as a black opal. It has to be a solid stone that has the black background on it’s own to be considered a black opal. The other can still be a beautiful effect, it’s just a different thing. This has been Your Jewelry Minute. If you have a jewelry question for me, just ask me in the comments below. Until next time!
