SSWO-F298.2 Gram (41.0 Carat) Ethiopian Welo Opal Rough-For Sale
This is a saturated blue opal that is created, I believe, by the black manganese coating on some Welo opals. It also saturates other colors as well. I don't see any fractures or internal matrix pockets.
Dimensions: 27mm x 23mm x 18mm thick.
8.2 grams or 41.0 carats.
