Well, I thought the middle looked like V which would tie into Steve V. Correia.; and the work in the links I gave seemed to be similar which is why I went that way.
If it's J as in Jon, then maybe "Stephen Jon Clements", that kinda fits. I know there are some paperweights/glass sculptures out there identified with that name but I can't find many examples online. I believe that artist is/was? out of Tucson AZ, USA.
