At PETRALO, we’ve always held a special love for opal — a gemstone unlike any other. While diamonds sparkle and sapphires shine, opals glow with an inner fire that feels alive. Their ever-shifting colors and fluid light make them more than beautiful — they’re deeply expressive, a gem that reflects emotion, energy, and individuality.
What Makes Opal So Unique
Unlike most gemstones that owe their color to chemical impurities, opal’s magic comes from its structure. Tiny silica spheres within the stone diffract light, creating the phenomenon known as play-of-color — flashes of blue, green, red, and violet that shift with every movement.
This living spectrum of light makes each opal one of a kind — no two stones ever share the same pattern. It’s not just a gemstone, but a moment of nature captured in color.
Why We Choose Australian Opals
We work exclusively with natural crystal opals from Australia, widely regarded as the most beautiful and stable in the world. Australia produces more than 90% of the world’s precious opals, and its stones are prized for their depth, clarity, and durability.
We never use synthetic or African opals, which are often less stable and prone to cracking. These alternatives simply can’t match the luminous depth and expressive fire of genuine Australian gems.
We’re especially drawn to crystal opal’s translucent body and vivid play-of-color. Shifting between blue-green and red-violet tones, each stone has a dreamlike glow that pairs effortlessly with both modern design and everyday wear.
Why Opal Is Perfect for Fine Jewelry
Every opal we use is untreated, hand-selected, and chosen for its exceptional clarity, color, and durability — ensuring your jewelry remains timeless and radiant.
Though opal is slightly softer than other gemstones, when properly set — especially in solid 14k or 18k gold — it becomes both elegant and lasting. Its luminous color and ethereal character bring warmth and individuality to every design.
Because no two Australian opals are ever the same, every PETRALO piece is truly one of a kind — just like the person who wears it.
