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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e✨ \u003cstrong\u003eKey Features\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\" dir=\"ltr\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBody Color\u003c\/strong\u003e: Deep black — the ideal dark backdrop for maximum fire contrast\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFire \/ Play-of-Color\u003c\/strong\u003e: Vivid red — the rarest and most sought-after opal fire color\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePattern\u003c\/strong\u003e: Directional flashes with rich, broad spectral hues\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eComposition\u003c\/strong\u003e: Silica with approximately 15–20% polymer resin (~15%)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eWorkability\u003c\/strong\u003e: 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\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: ~4 on the Mohs scale — best suited for faceted stones, cabochons, and inlay in protected settings\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeat Resistance\u003c\/strong\u003e: Up to ~140 °C (284 °F) — keep cool, low heat only\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBest For\u003c\/strong\u003e: Faceting, cabbing, inlay, intarsia, and statement jewelry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eA standout for anyone chasing the boldest, highest-contrast opal display.
