Why is it called Dark Iron Matrix? This type of boulder opal has a dark matrix and is as hard as iron. This allows for an extremely high-gloss polish, comparable to metal, although the reverse side requires significantly more work. The dark tone of the stone's body highlights the veins of colored opal embedded within the matrix. Photographs are difficult to take due to the stones' reflections. Dark Iron Matrix opals are among the most sought-after boulder opals!
