Impregnated Black Opal w/ Red Fire (15% Resin) – Faceting Rough

💎 15% Impregnated Black Opal w/ Red Fire — Dramatic Crimson Play-of-Color on a Dark Body

This lab-created opal is formed from microscopic silica spheres arranged into the precise, repeating lattice that gives opal its signature play-of-color, then infused with polymer resin (approximately 15%). A deep, dark body tone serves as the perfect backdrop for vivid, directional flashes of crimson fire, which ignite with striking intensity and shift across the stone as it turns. The 15–20% resin content places it in the middle of our opal lineup — more resilient and forgiving to cut than resin-free opal, yet harder and more durable than the high-resin Aurora material, and it takes a clean polish for both faceting and cabbing. Red is the rarest and most coveted of all opal fire colors, and paired with a black body it delivers maximum contrast and visual punch — a true showpiece material for faceted stones, cabochons, inlay, and statement jewelry.

• Pattern: Directional flashes with rich, broad spectral hues
• Composition: Silica with approximately 15–20% polymer resin (~15%)
• Workability: More resilient and forgiving to cut than resin-free opal, yet harder and more durable than high-resin Aurora material — suitable for both faceting and cabbing
• Hardness: ~4 on the Mohs scale — best suited for faceted stones, cabochons, and inlay in protected settings
• Heat Resistance: Up to ~140 °C (284 °F) — keep cool, low heat only

A standout for anyone chasing the boldest, highest-contrast opal display. Each piece is sold by weight.

📸 Additional Notes:

• Because this material contains resin, it has a heat limit around 140 °C (284 °F) — cut and polish wet, keep it cool, avoid ultrasonic cleaners, and use a cold dop or low-heat method rather than hot dop wax.
