N6 Dark Opals for Sale

Body tone N6 means the stone's underlying darkness is dark, shading toward grey. The N-scale runs from N1 (blackest) to N9 (near white) and is the single biggest driver of an opal's value at a given brightness — our body-tone guide shows the full scale with examples.

Every N6 stone below is natural solid Australian opal with a certificate stating its graded tone and brightness. Browse all dark opals, or jump to a neighbouring grade below.
