N4 Black Opals for Sale
Body tone N4 means the stone's underlying darkness is the lightest of the black grades. 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 N4 stone below is natural solid Australian opal with a certificate stating its graded tone and brightness. Browse all black opals, or jump to a neighbouring grade below.
