No two boulder opals are ever quite alike, but this one is particularly captivating. Across its natural dark matrix, flashes of electric green, blue, orange and fiery red appear as the light moves over the stone. We love that it isn’t perfectly uniform — its natural pattern is exactly what gives it character. Surrounded by diamonds and warm 18ct yellow gold, it feels luxurious without losing the wild, individual beauty that makes Australian boulder opal so special.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOne stone.
