The main differences between white opal, black opal, and common opal lie in their appearance, color play, and rarity:
White Opal:
Black Opal:
Common Opal (also known as potch when lacking play-of-color):
In summary, white opal and black opal are both types of precious opals distinguished by their body color and intensity of play-of-color. Common opal, on the other hand, lacks the distinctive play-of-color and is generally less valuable and more common.
Some opals are known as black opals, this is when they have a mainly black colour. In general a black opal is very dark blue and has flecks of other colours within
The value of opals and amethysts can vary depending on factors such as quality, size, and rarity. In general, high-quality opals can be more valuable than amethysts due to their uniqueness and play-of-color. Ultimately, it's best to have both evaluated by a professional to determine their worth accurately.
Yes. Coober Pedy is still a major producer of opals.
Three different types of Opal are found in Australia:Fire Opals are mined in South Australia near Coober Pedy.Black Opals are mined in New South Wales near Lightning Ridge.Boulder Opals are mined in the western Queensland.
Opals are generally elliptical in shape, are in some cases pear or spherical. Angular shapes for opals are not commonly seen.
The black opal is the rarest of all opals. It is only found in Australia. About 97 percent of all opals in the world are mined in Australia.
No. When opals were first found in Australia, they were not thought to be opals because they were a milky white in appearance. Opals found elsewhere in the world were mostly black.
The value of opals varies wildly as the play of color (fire) varies wildly. Opals do not have a fixed value such as gold and silver and the value is open to debate between the buyer and seller. Generally speaking.....if the opals are uncut and of moderate fire - they will not be very valuable.
Black opals can be found in Lightning Ridge, New South Wales, which is one of the most famous opal mining areas in Australia. Lightning Ridge is known for producing high-quality black opals, prized for their vibrant play of colors against a dark background.
Australian opal is the finest opal known and is exported around the world. It's safe to say that even the smallest gem and jewelry store in the smallest towns of the developed world will carry some Australian opal.
Nobody MADE opals. They're mined out of the ground.
To someone not familiar with Australian doublet and triplet opals, it would be difficult to tell the difference between them and solid opals when the stones have been set.Some of the ways to tell the difference are:The price - doublets and triplets are much less expensive than similar solid stones;Doublets have a thin slice of opal mounted on a black backing. If you can see the underside of the stone in the setting, you can tell whether it is a "black backing" or the stone;Triplets have a clear quartz cap on top of the opal in addition to the black backing. With a magnifying glass or incredible eyesight, you can see the thin clear layer on top of the stone.Jewelry with doublet and triplet opals has the same appearance as a solid opal. It's possible to find jewelry with amazingly brilliant colors at a reasonably affordable price when the stone is set as a doublet or triplet.
