Black w/ Rainbow Fire Aurora Opal - 80% Resin - Lab Created Faceting Rough

💎 Aurora Opal w/ Black Body & Rainbow Fire — 80% Resin, Swirling Non-Directional Play-of-Color

Aurora Opal is a lab-created hybrid opal formed from silica combined with a high proportion of polymer (approximately 80%), giving it a layered structure and excellent workability. Unlike directional opal types, the Aurora variety displays a swirling, non-directional play-of-color — flowing, iridescent flashes that roll and shift across the stone in the sweeping, luminous effect that gives Aurora its name. Here, a deep black body ignites with the full spectrum of rainbow fire, the dark base driving maximum contrast so every color in the swirl reads bold and brilliant. With its high polymer content, Aurora Opal cuts and polishes easily and is exceptionally forgiving to work, though it is soft and heat-sensitive — heat resistant only to about 140 °C (284 °F) — making it best suited to cabochons, inlay, intarsia, and carefully cut faceted stones.

✨ Key Features:

• Body Color: Deep black — the ideal dark backdrop for maximum fire contrast
• Fire / Play-of-Color: Full-spectrum rainbow flashes across the whole swirl
• Pattern: Swirling and non-directional — flowing, iridescent color unique to the Aurora type
• Composition: Silica with approximately 75–85% polymer resin (~80%)
• Structure: Layered, with excellent workability
• Workability: Soft, easy-cutting, and highly forgiving to work
• Hardness: Pencil hardness ~3–5H — soft; best for cabochons, inlay, and protected settings
• Heat Resistance: Up to ~140 °C (284 °F) — keep cool, low heat only
• Best For: Cabbing, inlay, intarsia, and faceted stones

The showpiece of the Aurora lineup — full rainbow fire at maximum contrast. Each piece is sold by weight.

📸 Additional Notes:

• This is a high-resin material with a heat limit around 140 °C (284 °F) — cut and polish wet, keep it cool at all times, avoid ultrasonic cleaners, and use a cold dop rather than hot dop wax. Excess heat will damage the stone.
