• Highlight: MK Diamond's MK-303 continuous rim delivers chip-free, glass-smooth edges on gemstones, agate, and jasper — the rimless edge eliminates the micro-fractures that segmented blades leave on brittle lapidary stones.
• Best For: Lapidary hobbyists, gem cutters, jewelry makers, and rock shop operators slicing thin slabs from raw stone for cabbing or facetting.
• Expert Note: The 4" (102mm) diameter pairs with most trim saws (1/2"-5/8" arbor), and the continuous diamond rim runs cooler in oil or water baths for cleaner cuts on brittle silicates.
