I found this giant rock a month or so back in Lake Michigan near South Haven, MI. I wasn’t sure exactly what it was at first as it had a very greenish hue. The rock was too big for my saw but I cut it anyway and was pleasantly surprised to see a fair amount of Petoskey stone embedded in the otherwise fossil laden matrix. After a very rough cut, I ground it down a bit on my grinding wheel then threw it into the sphere machine. I’m glad it was a soft rock or this thing would have taken forever as out of round as it first was. Once I started this one, I had to see it through til the end. Total time just under 4 hours. Not bad. And boy is it a beauty!. It is about 3.85 inches in diameter. Check it out! I also made a few Jasper pendants.
