Nice!
Kind of comforting to hear my hair-splitting is understood!
When I took out my onyxes last night, eureka, I had one very like the new one except the base color was clearly amber and not UV reactive. The two looked lovely together. So much so that I separated them out from the onyxes (my onyxes tend to have thinner corks with multiple wraps).
A sub-category of onyxes. You understand, right?
