• Highlight: MK Diamond MK-303 24" (610 mm) Professional segmented-rim lapidary blade — premium choice for cutting the largest gemstone rough in production slab saws.
• Best For: Production lapidary shops slabbing large agate logs, petrified wood, jasper, and other oversize hardstone rough where throughput and blade life both matter.
• Expert Note: Owners report the MK-303 at this size cuts faster and lasts longer than notched or plated alternatives when run with oil-based coolant — never water, never dry.
