This opal is very lively, showing off very bright, and very rich fiery colours that show all of the time. The deep and strong, bright cherry red, blends to perfection with a mix of green, orange and blues. The peacock blue lays slightly deeper, just underneath the red, a gorgeous shade that contrasts and lifts the show that little extra, making a truly gem quality opal. All colours move with vivid splendor, very, very bright. From every single angle, the show is at its best, the colours are always on show. A constant display of colours that are ever present. The opal has a medium dome and is fantastic in all lights.

Fake opals are produced by synthesizing the silica beads that form natural opal. Fake opals are easy to spot by their regular play-of-colour due to identically sized silica beads.
An experienced eye should be able to distinguish a fake opal from a natural solid opal with ease. A trick of the trade is to hold the natural and fake opals up against the light. A natural opal should go entirely translucent, however a fake opal will not. In the case of a boulder opal or doublet opal, a high powered camera flash can be used to take an image of the stone. Should the stone be real, the flash will turn the opal translucent and illuminate the stone or plastic backing.
Fake opals hold very little value and we DO NOT deal in any fake opals.
Boulder Opals are natural formations of thin opal on ironstone. The opal appears naturally in thin seams between the ironstone rock, and is cut in such a way as to retain the ironstone backing.
Boulder Opal is very strong because of the naturally melded ironstone, and the dark backing gives the opals the same benefit as a dark backing on a doublet opal, however the value of boulder opals is higher since this occurs naturally.
Queensland Boulder Opal is know to display fantastic colours similar to black opals. They can be cut into oval pieces, but are more often cut into irregular shapes that make for fantastic pendants.
You should be weary of buying boulder opals on a per carat basis as the ironstone is heavy and has very little value, however boulder opals are far more valuable than doublet opals and triplet opals..
Lapidists (gem cutters) need to be especially careful when working with boulder opals as the ironstone is much harder than the opal, and as such, the opal wears away more quickly during the polishing process.
A Triplet Opal is similar to a doublet opal in that it is a man made stack of different materials, including some real opal. In the case of a Triplet Opal, the slice of opal is generally paper thin.
This paper thin slice of opal is mounted on a dark background of stone or plastic in the same way that adoublet opals are, however a Triplet Opal then has a dome of clear crystal, glass or plastic over the top of the opal which has the effect of magnifying the colours.
Triplet Opals can make stunning pieces of jewelery, however they are easy to spot to an experienced person.
A Triplet Opal may have very bright colours, however the Play-Of-Colour will generally be poor. One benefit of Triplet Opals is that the clear dome will protect the opal from direct abrasion.
Triplet Opals are the least expensive form of opal since they contain only a very small amount of real opal. They can only be valued on the top down dimensions of a stone, rather than the carat weight, since plastic has no gemstone value. They are best mounted in silver or stainless steel jewellery.
Doublet Opals are a man made gem which uses a thin slice of real solid opal, and attaches it to a black stone or plastic backing to enhance the stones colour. If the stone is mounted so that the back and sides aren’t visible, it can be difficult to differentiate a doublet opal from a solid opal.
Doublet Opals can’t be valued by carat weight as the black stone or plastic is valueless. However based on the brightness, play of colour, pattern and size, we can come to a valuation.
Doublet opals are best matched with a silver or 9kt gold mounting. They are a great option for less expensive jewellery as the stones aren’t as expensive as solid opals.
