Shakespeare called opal “the queen of gems.” Queen Victoria’s love of opals started a major fashion trend around the turn of the century.
Opal has an especially fascinating folklore. It’s been said that the opal contains all the other gemstones, which explains the vast number of magical properties attributed to it over the centuries. They range from easing childbirth to granting the wearer a makeshift “invisibility cloak.” But above all, it is universally recognized as a symbol of hope and love.

Opals are silica-based precious stones that contain compressed water. Internal characteristics like gas bubbles, traces of other minerals, or even organic materials trapped inside result in the fascinating flashes of light and color that make this stone so popular.
95% of opals come from Australia, making it the country’s national gem, but they are also found in Central America, Japan & Ireland.
Types of opal
In general, the more color an opal has, the greater its value. White opal is the most common. Its color is similar to mother of pearl, with faint color patches on a milky background. Crystal opals are rarer and have a smooth, lustrous finish. Australia’s black opals are the most desirable of all, with their striking brilliant colors.

Care for opals in much the same way as you treat pearls. Avoid acids and solvents, prevent sharp blows and scratches, and clean frequently with a soft, moist cloth.
Alternative Birthstone: Tourmaline
Tourmaline is a complex mineral crystal whose composition determines its color – in fact it’s one of the only gemstones available in all the colors of the rainbow. If October is your month, you can take your pick of colors from the huge tourmaline palette – though the pink and green varieties are traditionally the most prized.
Tourmaline has very unusual reactions to heat and pressure. They are piezoelectric – taking on a static charge under friction. Many are also pyroelectric – when heated, their atomic structure becomes polarized so that they carry a low electric voltage.
Sometimes called the “peace stone,” it’s also a symbol of hope like the opal. It is believed to bestow the wearer with energy, creativity, and romance.
