These wheels are most often employed to create starburst, sunray, and channel-like patterns on the crown, table, or pavilion of gemstones. The V-profile makes it possible to add both functional depth and decorative geometry, greatly enhancing light performance and visual appeal. In fantasy faceting competitions, V-Groove Wheels are invaluable for achieving unusual reflective effects that set stones apart from standard designs. They are available in a range of included angles, most commonly 60Ā° and 90Ā°, giving the cutter flexibility in shaping either deeper, narrower grooves or wider, bolder channels.
V-Groove Wheels are produced in multiple grit sizes to accommodate different stages of cutting. Coarse options, such as 260 mesh, are well suited for fast material removal and shaping. Medium grits, such as 600 mesh, refine the groove and prepare it for polishing. Fine grits, ranging from 1200 to 3000 mesh, allow for smooth pre-polish surfaces that reduce the time and effort required in final finishing. Their construction and grit selection make them suitable for a wide variety of materials, from quartz and topaz to corundum species like sapphire and spinel, as well as synthetic gemstones.
