Onionskin's have an underlying skin (Thus the name "Onionskin") usually of yellow or white w/ any number of colored bands stretched over it. Joseph coats are minus the skin and generally have a window between the colored ribbons to the transparent interior of the marble. (I should note there are always exceptions as in the case of any marble)
ONIONSKIN W/ A YELLOW SKIN ::
ONIONSKIN W/ A WHITE SKIN ::
JOSEPH COATS ::
Beach Ball type Coat :
Orange Joseph Coat (Backlit so you can see the windows between the ribbons)
And a couple shots of the same marble under normal lighting :
Last year !! Just enough for dinner Me and my family bought for local & export 18 varieties of wild & exotic gourmet mushrooms,Chanterelles were one of our mainstays.
In my mind there is transparent, which could be any color of clear base, & transparent clear which would indicate a total lack of color in the base, depends if you put the words (transparent & clear) together or not as to the specific meaning.
Hmm, might be a wolf, the base in the OP looks blue to me ?? Maybe be a newer or different run ??
