I'llhavethat1 Posted October 10, 2010 Report Share Posted October 10, 2010 Had a recent question about pontils and am throwing this one out for the broader knowledge base! What do you think? Link to comment Share on other sites More sharing options...
lstmmrbls Posted October 11, 2010 Report Share Posted October 11, 2010 Does it look like this Link to comment Share on other sites More sharing options...
I'llhavethat1 Posted October 11, 2010 Author Report Share Posted October 11, 2010 Wow, nice close up! Are those scuffs (horizontal) or a trick of the light? Here's the best detail I could get of the type. Almost looks flame polished or something, smooth The pontils on these are all similar but the blue one showed the most detail close up. They don't look ground from what I see, but they're not pronounced either. smooth Added second pic since the blue marble may have seemed out of context (compared to the green one from my first post!). Green one is bottom right. All around 7/8" or so Link to comment Share on other sites More sharing options...
lstmmrbls Posted October 11, 2010 Report Share Posted October 11, 2010 Ground pontils show obvious signs that the pontil was ground off with a grinding wheel. Some wheels are finer than others here are a couple done with fine wheels. Those may be Foreign handgathered machine rounded slags (true transitionals) Link to comment Share on other sites More sharing options...
I'llhavethat1 Posted October 11, 2010 Author Report Share Posted October 11, 2010 The construction looks like they should have a more noticeable pontil. Flip them over and it's more of a bump, no evidence of grinding or even very fine facets. Just a raised portion that looks like it might have been polished with heat. No "wrinkles" on or around the point Maybe they are machine rounded?? I figured a machine would make them more spherical? Thanks for those pics and quick response, I can see the grinding on yours.

lstmmrbls Posted October 12, 2010 Report Share Posted October 12, 2010 Interesting. Guess I would need to see in hand. They really do not look like a type I am familiar with. And if not round probably not machine rounded. Link to comment Share on other sites More sharing options...
