Understanding Rough Opal
What is rough opal?
Rough opal is natural, uncut opal straight from the mine. It hasn’t been shaped or polished, making it ideal for lapidary work, collecting, or jewellery making.
What types of opal are there?
Opals are generally categorized into:
- Precious opal: Displays a play-of-color (rainbow-like flashes).
- Common opal: Lacks play-of-color but can have attractive hues.
- Doublets & triplets: Assembled stones made from thin opal slices bonded to backing materials, sometimes with a protective top layer.
Where do opals come from?
Australia is renowned for its opal fields, including Lightning Ridge (black opal), Coober Pedy (white opal), and Queensland (boulder opal). Other notable sources include Ethiopia, Mexico, and Brazil.
Buying & Working with Rough Opal
Is buying rough opal risky?
Yes, purchasing rough opal can be speculative since the true color and pattern often only emerge after cutting. Many parcels look promising externally but reveal imperfections or potch when opened.
What should I look for when buying rough opal?
Look for visible color bars, minimal cracks, and a stable matrix. Beginners might start with more affordable parcels to practice cutting and polishing techniques.
Is cutting opal difficult?
Cutting opal requires patience and practice. Some types, like white opal, are easier to work with, while others, like black opal, can be more challenging due to their structure and value.
Caring for Opals
How should I store rough opal?
Store specimen-grade rough opals submerged in water to maintain hydration and prevent cracking from dehydration.
Can opals get wet?
Yes, opals can get wet. However, avoid exposing them to rapid temperature changes or harsh chemicals, which can cause damage.
How do I clean opals?
Gently clean opals with a soft, damp cloth. Avoid ultrasonic cleaners, steamers, and abrasive materials.
