About Opal
    Opal is a very beautiful gemstone which contains all gemstones' colors, there is no other gemstone in existence as special as a opal. One individual opal can contain a world of colors, a brilliant dazzling rainbow fire which enchanting and changing with every light condition and any directions.
     Opal, accepted as the " Queen of Gems", is the National Gemstone of Australia and one of the world's six precious stones (with diamonds, rubies, sapphires, emeralds and pearls). More than 90% of the world's quality opals come from Southern Australia.
     Most opal is more than 60 million years old and generally dates back to the Cretaceous period when dinosaurs roamed the earth. Numerous legends and tales surround this colorful gemstone, which can be traced back in its origins to a time long before our memory, to the ancient dream time of the Australian aborigines. It is reported in their legends that the creator came down to Earth on a rainbow, in order to bring the message of peace to all the humans. And at the very spot, where his foot touched the ground, the stones became alive and started sparkling in all the colors of the rainbow. That was the birth of the Opals.
     Opal is a wondrous gemstone with a chemical composition of  SiO2nH20, a hydrous silicon dioxide combined with water, the hardness is measured at 6.0 to 6.5 on the Mohs' scale.
     Each and every piece of opal is unique. No two stones are exactly alike. The group of fine Opals includes various wonderful gemstones, but which share one characteristic: they shine and sparkle in a continually changing play of colors full of fantasy, which experts describe as "opalising". Depending on the kind, place of occurrence, and color of the main body, we differentiate Dark or Black Opal, White or Light Opal, Milk or Crystal Opal, Boulder Opal, Opal Matrix, Yowah Nuts from Queensland ¨C the so-called "picture stones", and also Mexican and Fire Opal. Opal variations are practically unlimited. They all show in their own special way that unique play of colors ¨C except for Fire Opal, which due to its transparency, however, is nevertheless also considered a Fine Opal specimen.
     In order to best bring out the play of color in a Fine Opal, the stones are cut and polished to round or oval cabochons, or any other softly domed shape, depending on the raw material. Only the best qualities of Fire Opal, however, are suited to faceting. The Opal cutter will first of all carefully remove any impurities using a diamond cutting wheel, before working out the rough basic shape. The comes the fine cutting, the finishing with sandpaper and then the final polishing with a wet leather wheel.
     Opal is often found as flat lenses, or thin layers, bigger pieces are rather rare. If you leave a thin but supporting layer of the harder mother rock, you will receive a pre-stage of the Opal-doublets which are frequently used today for mass produced jewelry. These are gemstone combinations consisting of a surface from millimetre-thin Opal plates, which have been mounted on Onyx, Obsidian, artificial black glass, or Potch-Opal. Triplets have been developed from this design, here the Opal layer receives an additional cover from Rock Crystal, Plastic, Hard Glass or Lead Glass for protection. Below are brief definitions for some main types of opal.
 
Black Opal
It is the most valuable. It is the most colorful with dark appearance distinguishes it from other opals.
White Opal
It is mainly opaque, milky white with speckles, flashes, or sheets of rainbow colors,
Crystal Opal
It is transparent or translucent and display a variety of colors.
Boulder Opal
It is a naturally formed solid opal which consists of a fine layer of opal that has been deposited by nature on and in the fissures of ironstone base rock.
Opal Doublet
It consist of a layer or slice of precious natural opal which has been bonded to a dark or black backing. The backing can be potch, black glass or ironstone boulder. The dark backing enhances the color and simulates high quality black opal. The opal doublets cost much less than a solid black opal since it less opal material.
Opal Triplet
It is essentially a doublet capped by clear quartz cap. The quartz cap can not only prevents damage in setting and protects the actual opal from wear, but also acts as a magnifying glass to enlarging the color play and giving more of the appearance of fine black opal.
Mosaic Opal
It consists of tightly fitted, irregular pieces of opal, carefully fitted to create a brilliant mosaic. This allows smaller, colorful chips of opal to be utilized rather than discarded.
Synthetic Opal
It is a laboratory grown opal, which has essentially the same physical, optical, and chemical properties as natural opal.
