This glass is NEW, CUT FROM MY GLASS SHOP in Kalkaska Mi. The diameter is 3 1/32" diameter and 0.077" thick, much THINNER than normal window pane thickness for those who would understand thickness better in layman's terms. I have several other diameters available. PLEASE MESSAGE ME FOR QUOTES On your size request Thanks for looking!
