Pliny the Elder, a Roman scholar from 23 - 79 AD, described Opal as having "the burning fire of the Carbuncle or Ruby, the glorious purple of the Amethyst, the green sea of the Emerald and all glittering together, mixed after an incredible manner." He admired Opal for its ability to display a wide range of colours.

Opal held great significance in various cultures. The Aztecs worshipped it as the "stone of the bird of paradise," Ancient Indians and Persians saw it as a symbol of ardent love, and Ancient Greeks believed it had protective properties against disease. Opal was also highly valued by the Romans, who used it to showcase their wealth and status.

Opal was indeed considered a precious gemstone in the past. It was highly regarded for its scintillating play of colour and its ability to mimic the vibrant hues of other gemstones. This led to Opal being considered the "queen of gems" by William Shakespeare in his play *Twelfth Night*.

Opals have been associated with both good and bad luck throughout history. In the early 19th century, negative superstitions surrounding Opal led to its decline in popularity. However, Queen Victoria's endorsement and subsequent wearing of Opal helped dispel these negative connotations and revived its popularity.

Queen Victoria played a pivotal role in revitalising the popularity of Opal.

Her endorsement helped change the perception of Opal and restored its status as a desirable and beautiful gem.

Opal is a hydrated amorphous form of silica (SiO2·nH2O) that is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock. Unlike crystalline forms of silica, it is considered a mineraloid and is most commonly found with limonite, sandstone, rhyolite, marl, and basalt.

The formula for Opal is hydrated silica (SiO2·nH2O). The water content in Opal can range from 3 to 21% by weight but is typically between 6 and 10%.

Opal can be colourless, white, yellow, red, orange, green, brown, black, blue, or pink. It has an amorphous crystal system commonly found in irregular veins, masses, and nodules. Opal has no cleavage and exhibits conchoidal to uneven fracture. It has a Mohs scale hardness of 5.5-6 and a subvitreous to waxy lustre. Opal's streak is white and can be opaque, translucent, or transparent, depending on the specimen.

Opal is single-refractive but can exhibit anomalous double refraction due to strain. Its refractive index is typically between 1.450 and 1.43, with Mexican Opal sometimes reading as low as 1.37. Opal may exhibit pleochroism, but birefringence is absent. Under ultraviolet light, different types of Opal may fluoresce in various colours ranging from white to moderate light blue, green, or yellow. Absorption spectra of green Opal stones show peaks at 660 nm and have a cutoff at 470 nm.

A diagnostic feature of Opal is its tendency to darken upon heating. It is soluble in hot salt water, bases, methanol, humic acid, and hydrofluoric acid.

Two broad classes of Opal are recognised: precious Opal and common Opal. Precious Opal displays play-of-colour, a pseudo-chromatic optical effect resulting in flashes of coloured light. It has an ordered internal structure of silica spheres in a hexagonal or cubic close-packed lattice. On the other hand, common Opal does not exhibit play-of-colour and often has a hazy-milky-turbid sheen. It lacks the internal structure and regularity of precious Opal.
