From the seller's description. Not a guarantee of condition.
A natural 2.50 carat cabochon opal described as AAA+ with multicolor flashes and no treatment detected. Buyers are gemstone dealers, jewelry makers, and estate jewelers who set loose stones. The listing says the condition is shown in the photo taken under a light, so compare the photo for chips, crazing, or dullness. Verify the stone's origin and treatment status with a gemologist, since the listing's no-treatment claim is only a detection note.
Estimated flip margin and comp range available with Pro. Summary may occasionally contain inaccuracies; check the full description before bidding.
