Hi all. I bought theese at a local antique shop today. Bought them both for $50 the man I bought them from said he found the localy in thee 80s. My thing is that they are light. Trying to figure out the stone they are made from. The reason I say they are light is I was lucky enough to find one myself a few years back and I am only one town over and mine is twice the weight. They are definitly stone but it sounds like glass when I tap it with anouther stone but mine sounds more dense.

i Hate to make a fake call, but the first three photos of the second piece at normal size sure look like air bubbles. at 400% they really pop out at you as air bubbles, fourth photo is to blured to see. I hope someone can show some artifacts they know are real say by finding them there self with these air bubble looking holes and prove me wrong. TERRY
