opinion on tritium pearl

[larryccf]

I'm not that familiar with luminova pearls but rcvd an insert that is represented as NOS with tritium pearl.

I've placed a loose known tritium pearl just above the subject pearl and while i don't know luminova, it would seem if it were tritium, there'd be some aging as tritium hasn't been used for quite a while, NOS or not, and the white color filling the entire pearl out to it's edges would seem to be what luminova would look like

any assist appreciated
