Looks like Beckett has graded my #16 diamond 1/1 as an onyx 1/1. grade got a 10. card is in production stage and has not shipped. I tried to call them with no answer, so I sent them an email to see if they can hold if for further review and correct labeling. May want to wait a little if you are thinking about submitting your diamonds to BGS.
A BGS 10 hard to come by. Can you tell if it is super rare black label. If so maybe don't risk re stabbing it
