Covington Gem Marking Templates Covington’s Gem Templates are a basic piece of lapidary hardware used to scribe cabochon shapes on rock slabs prior to trim sawing. These templates are colorful and easy to recognize. They're available in plastic or anodized aluminum. The aluminum version measure .030" thick and are rigid, making them excellent for quick measuring or stenciling. They are also durable and long lasting. Plastic templates are clear which makes marking your rock easy. Both sides of a cabochon may be scribed by placing a slab between 2 connected templates (doubles) and outlining each side. Grinding proceeds faster and more accurately using this method. These templates are available in singles or doubles, and as sets. Sets come with an aluminum scribe. Simply choose your template shape (color coded) and which style you would like. Please note that doubles are not available in sets.
