Opal is a sub-gemstone
of white color. There are splatters of various colors on its surface. This
gemstone is very soft and tender and breaks with a small hit. White color
stone named Opel in English has been derived from Latin work Opulus which has the meaning
“like jewelry”. As per one more piece of information, the word opal has come from the Sanskrit
word Upal which means a “precious stone”.

How to test in original gemstone
Look at the back of the opal - does it look or feel like a kind of hard black or grey plastic? Triplets are often glued onto a black plastic, glass, or vitrolite backing. Doublets are a little more difficult to identify, as they often use a natural potch (black, colorless opal) or ironstone (the brown boulder opal host rock) backing. In this case, look at the side of the stone again and see if the 'join' between the opal and the backing is perfectly flat (i.e. the line around the circumference is perfectly straight). Most genuine solid opals have an irregularity in this area - curved or bumpy due to their natural formation - whereas a man-made stone will be perfectly flat because the two sections are flattened so they can be glued together. Be especially wary if the opal is set in jewelry and you cannot see its back or side. Even an expert will have difficulty identifying a doublet set once it's set in jewelry with the back & sides covered.
Be educated before you buy. Know what real opal looks like, and compare what you have seen to what you are buying. People have been known to set colored tinsel or foil underneath clear plastic to make an 'imitation opal'.
Synthetic solid opal can be very difficult to identify, unless you are an expert, or have a lot of experience. Look closely at the pattern - Opal created in a laboratory (Gilson opal), displays bright colors in large patches of color. The pattern is often 'too perfect' and ordered, and can also often display a 'snakeskin' pattern. If you are still not sure, take it to a gemologist or an opal expert.
