Rare Brown Lines clambroth. The lines are pretty evenly spaced and almost has a purplish brown color.  There's a wobble in some of the lines from an as-made tool touch mark that gives it character, and is a little wider than it is pontil to pontil. Absolutely Wet Mint original condition!

Pink clambroth with 11 equal-distant lines that course across the marble at a 45 degree angle giving it a real nice visual appeal. Clambroths are inherently made of brittle glass type, and it's getting increasingly difficult to find mint like this one.  Also the size is a little larger than average.

Desirable and hard-to-find 14-line 3-color clambroth of a repeating red-blue-red-green pattern over a white semi-translucent base with some as-made opaque spots. Inherently clambroths are made of very soft glass and are a difficult type to find undamaged. This one is mint!
