This glass is NEW, CUT FROM MY GLASS SHOP in Kalkaska Mi. The diameter is 5 1/2" diameter and 1/8" thick, much thicker 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!
