Hey VTAndrea:
I think you are referring to the middle marble in this pic, correct?
Hard to see but this shooter is a clear based striped transparent. The surface is just about 100% covered with a creamy orange opaque "film" of color, to the extent that there is only one (very) small window to look through with maglight back lighting to see that the base glass is actually clear. Looking through any other surface location with back lighting, the mib looks like it has a creamy orange translucent base.
