What is Opal?
A translucent to transparent semi-precious gemstone, the shimmering milky to pearly iridescence of opal has captivated jewelry lovers for centuries. Well-loved as the birthstone for October, opal is an opalescent stone of the silica mineral family, which includes quartz and cristobalite. A distinctive feature of opal is the way its ivory white to pearly pink or pale blue colors shimmer and change as the stone is moved in different directions, a phenomena caused by the magical interplay of light among mineral cracks in the stone.
What does Opal look like?
Opal is perhaps most well-known for its milky white to pearly pastel shades, which dance with rainbow like colors as the stone is viewed from different angles. However, these enchanting hues are a feature of precious opals, also known as ‘noble opals’, which dance with fire or exhibit the spectral ‘play of color’. Common opal is opaque to translucent and does not show a play of colors.
Opals come in many other colors other than that of cloudy white, the rarest of which is black. Highly prized by collectors, black opal has a dark blue to grayish or black body color, and are ‘fiery’, or lit up from within by a spectacular interplay of greens, blues, yellows and reds.
Fire opals are quite unique in the opal world, and come in various shades of yellow, bright orange and burnished gold. These opals also possess the phenomenon known as ‘play of color’, which results in spots, flashes, and sparkles of different colors that race across the stone’s surface, making the stone burn from within with the vibrancy and brightness of fire itself.
History of Opal
Throughout history, opal has been celebrated for its magical qualities and bewitching colors, which have led to the stone being poetically named ‘Pandora’ and ‘Light of the world’. Arabic legends describe the way opal falls from the skies in flashes of lightning, and the stone has long been imbued with supernatural powers. In Ancient times, it was believed that opal possessed all the virtues of the gemstones whose colors flicker within it, and thus opal earned its reputation as the ‘Queen of Gems’.
In Europe, opal is associated with hope, purity, and truth, and Queen Victoria gifted each one of her five daughters with opals on their wedding day.
Many tales and legends surround the orange to red Mexican fire opals.
Meaning of Opal
Many scholars believe that the opal gets its name from the Latin ‘opalus’ which itself is possibly derived from the Ancient Greek ‘opallius’ which means color changing. However, others maintain that opal takes its name from the Sanskrit ‘upala’ which means precious stone or jewel. The spiritual meaning of opal is that of hope, purity and truth. It is also known as a seductive stone that intensifies or amplifies emotional states and releases inhibitions. In the highlands of Mexico, the bold, brilliant lights of the amber firestones symbolize the deepest and strongest love.

Not being tied to a single color means that October babies are given the freedom to match their own tastes and styles to whichever shade or tone of the stone they please.
