3.90 ct Fire Opal — Oval Modified Brilliant Cut
Collector’s Note
Warm orange color gives this 3.90 ct natural Mexican fire opal an immediate presence. Its oval modified brilliant cut brings flashes of light across the face, while a faint play-of-color appears in direct sunlight — a subtle extra detail to discover as you turn the stone. With a generous 13.06 mm length, it is an inviting choice for an opal collection or a distinctive pendant.
