Interesting Facts About Opals
Opals are one of the world's most sought-after gemstones. Their shimmering beauty is unique, making them perfect additions to jewellery collections. The incredible, kaleidoscopic play-of-colour they display makes them a favourite with geologists, jewellers, and astute collectors.
How much do you know about this incredible gemstone? Read on to learn some interesting facts about opals.
- There are two varieties of opal common and precious. The difference lies in the optical effect they produce.
- There is more than one opal colour: the "colour" of a precious opal refers to the background colour of the stone (typically white, green, or translucent), with common opals often seen in hues of purple, pink, blue, and green. Common opals are frequently mistaken for varieties of quartz due to their modest appearance.
- Opals are minerals, not crystals: a hydrated amorphous form of silica opals are considered a mineraloid, similarly to obsidian, amber and pearl.
- The opal is Australia's national gemstone: our nation mines over 95% of the world's precious opals for use in jewellery, and Indigenous Australian myths frequently link the creation of opals with rainbows, referring to them as the rainbow stone.
- Black is the rarest opal colour: black opal gemstones have only been discovered in Australia, around Lightning Ridge.
- Opal is the birthstone of October: believed to bring good luck, health, and fortune to its wearer.
As with many precious gemstones, you grade opals on a scale. The Brightness Scale is graded, categorising opals based on how intense the reflection of colour is when you penetrate the stone with light. The grades are Dull/Subdued, Bright, and Brilliant.
Brilliant grade opals are the brightest and contain eye-catching flashes of colour, also make it the most expensive and desirable gems. Dull/Subdued opals are the least valuable and appear milky with little shine. Bright opals are average in terms of brightness and often an affordable choice.
