Upgrade your cabbing process to utilize Diamond Pacific Nova diamond laps to quickly polish your cabochon backs without the mess of traditional diamond compounds. By fusing a lap of Diamond Pacific's Nova resin-bond diamond to a magnet disc base, these Nova discs offer reliable and efficient polishing performance with the convenience of an easy-to-swap magnetic lap. These discs mount magnetically to steel master laps and are easily removed.



Nova Magnetic Discs are made by Diamond Pacific in California with a 1/16 inch thick backing of solid rubber containing magnetized iron particles. The rubber is coated with a thick layer of Diamond Pacific's special Nova resin-bond diamond formula in a grid pattern for fast action and long lap life. Diamond Pacific utilizes an extra-concentrated amount of diamonds in the Nova resin layer to provide a durable and fast-cutting lap for professional lapidaries and jewelers creating custom body jewelry, cabochons, or intarsia where time and accuracy is key.

Selection and Compatibility

Quickly mount Diamond Pacific magnetic Nova laps to a no-hole spin-on back plate on your lapidary cabbing machine to work out the scratches left by grinding with magnetic plated diamond discs or spin-on plated laps. Start with a proven general purpose grit sequence recommended by Diamond Pacific for sanding most lapidary stone flats using 30-60-280-600-1200 grit Nova diamond laps followed by your favorite lapidary polish on a canvas polishing pad. This combination will put an excellent polish on most stones, while some hard-to-polish material or deep saw or lapping marks may require more steps such as a coarse-grit magnetic diamond plated lap, additional grit magnetic sanding laps, or lapidary polish compounds like diamond paste or cerium oxide polish. These Nova discs will also adhere magnetically to a cast iron or nickel lap you may already have for working lapidary material flat surfaces. Magnetic Nova laps do not have a padding layer, use standard Nova laps to conform to curved or domed surfaces. You can use the Magnetic Novas Laps on your present flat lap setup in most cases but they will not work on aluminum or diamond-coated discs.
