Скачать или смотреть Mintabie Solid Opal – 2.475 ct Oval Cabochon – Red Blue Green Rainbow Fire

This Mintabie opal features a striking dark-to-medium base tone (estimated N3–N6) with subtle transparency and an exceptionally vivid play-of-color. The polished face displays a smooth, slightly smoky grey surface that enhances multicolor fire — while the back transitions into a deeper tone, revealing the stone’s semi-crystal structure and internal depth.

Cut from high-grade Mintabie rough, the stone was shaped into a mirror-polished oval cabochon. Fire shifts fluidly across the face as the stone moves, flashing intense reds, oranges, greens, blues, violets, and yellows under both natural and artificial light.
