There are 4 main types of natural opal stones, namely Black Opal, Boulder Opal, White Opal and Crystal Opal. The rarest and therefore the most expensive is Black Opal. The body of the stone can range from a dark grey to an almost black and this dark coloring allows the fire of the opal to flash in an exceptional way.
Boulder Opal stones are found only in Queensland, Australia where they form in the cracks of ironstone boulders. This means they are exceptionally thin stones and are usually cut with a layer of the boulder still attached to give the stone the strength to be usable in jewelry.
The most common form of opal stone is the white opal. It formed in almost the exact same conditions as black opal but the carbon and iron oxide trace elements that give the black opal its darker color were not present. White Opal gemstones are the least expensive of all opals and are often used in rings and pendants of all types.
Crystal Opal stones are any type of opal in which the body of the stone is transparent. The colors range mainly from yellow to oranges but can be other colors. The stones transparency allows the flash of fire to show through making this gemstone not quiet as valuable as black opal but on a level with boulder opal.
It is important to note that opal stones are also being made synthetically. The fire flash tends to be stronger but more squared in synthetic opals giving the stone a somewhat snakeskin pattern across the face of the stone.
A gem cutter will always prefer to cut opal stones as a single, solid stone but opals are very fragile and this sometimes means they can not stand up to the pressure of finishing the piece. Cutters will often make doublets or triplets for the stones by layering one or two slices of thin opal and gluing it to a thin slice of a dark colored base stone. This makes for an exceptionally beautiful stone and many collectors seek out these stones in particular.
