Seven-step diamond polishing systems deliver the highest possible surface gloss on natural stone — essential for dark granites, absolute black, premium marbles, and any material where subsurface scratches would show through a reflective finish. Seven calibrated grit stages remove each previous scratch pattern completely. 

Used by high-end stone fabrication shops and restoration specialists on premium residential and commercial projects where polish quality is non-negotiable. The 7-step sequence produces a deeper, more durable gloss than shorter systems — and one that holds up better under daily use. 

All pads are hook & loop backed for angle grinder use. Available as complete sets. For less demanding applications or higher-volume production work see 3 Step Diamond Pads and 5 Step Diamond Pads.
