Master Transparent Bee?

In hand the black looks opaque, but when back lit it is transparent, as seen in the last 2 photos.

It's 39/64 (.60) inches.

Marble King, my marble collecting friend.

A nice one for sure.

@Melissa may have some thoughts here.

Marble--On!!

X2, MK but no names from me, as said  @ @Melissa  would be your best bet here IMO

Thanks folks. I totally meant Marble King, but typed Master by mistake. (I had just been searching for Master Sunbursts prior to this post.)

P.S. I grew up calling these "Bumble Bees", so to me, that is what they are. Not trying to offend anyone else's naming preferences, but we all have our own experiences, so please forgive me if I continue to call them by that name.
