Folklore says that when God completed painting the Universe, the scraped palette was dumped into the colours of a stone - the Opal!
Opals are the birth stones of the October born. They have also been used by clairvoyants.
The name Opal was probably derived from Sanskrit "Upala", meaning"valuable stone".
The famous Roman author, Pliny called Opal a gemstone which combines the best possible characteristics of the most beautiful of gemstones: the sparkle of Almandine, the shining purple of Amethyst, the golden yellow of Topaz, and the deep blue of Sapphire,"so that all colours shine and sparkle together in a beautiful combination".
Opals were relatively rare up to the first half of the nineteenth century, but then their popularity boomed suddenly and made them one of the most popular gemstones. The start of this development brought them to the gemstone cutters of the gemstone centre of Idar-Oberstein. In the age of Art Deco, the Opals experienced their first brush with limelight, with contemporary gemstone artists preferring them to all other stones because of their discreet charm, which in turn was perfectly suited to be combined with enamel, another very popular material of those days.
Opal's colour play emanates a very special attraction and fascination. What causes this phenomenon is a question which was impossible to answer for a very long time. Only when in the 1960's a team of Australian scientists analyzed Opals with an electron microscope, it was discovered that small spheres from silica gel caused interference and refraction manifestations, which are responsible for the fantastic play of colours. The spheres, which are arranged in more or less compact structures, succeed in dissecting the light on its passage through the gemstone and turning it into all the colours of the rainbow, always new and always unique.
Opals are soft and relatively susceptible to scratches. They are delicate and need to be handled with a lot of 'Tender loving care.'
Never steam or provide ultrasonic as the vibrations may crack them. It is also recommended that you avoid commercial jewellery cleaners as they may crack and seep into the gem leaving it discoloured with an obvious and an unattractive flaw.
Among the Opals the black which is found in Australia is the rarest and the
most expensive. They can be translucent or opaque, with the play of colours
occurring against a purple, dark blue or a black background.
