GreenWay polish — also encountered in the trade as Greenway compound — is a proprietary polishing preparation formulated specifically for use with GreenWay composite laps. It is supplied as a paste or water-miscible slurry and is applied directly to the lap surface during the final polishing stage of gem cutting. The compound suspends fine abrasive particles in a carrier medium that keeps the working surface consistently charged without flooding or drying out prematurely.

Composition and Working Characteristics

Like most commercially prepared polishing compounds, GreenWay polish relies on a fine-particle abrasive — the exact formulation is proprietary — held in suspension within a water-miscible binder. The water-miscible carrier allows the lapidary to thin the compound with plain water to adjust cutting aggressiveness and to clean the lap between sessions without solvent. The particle size is calibrated to the softer working surface of the GreenWay composite lap, producing a consistent scratch pattern that the polishing stage can then refine to a high lustre.

Because the compound is matched to the compliance and porosity of the composite lap material, it performs less predictably on harder substrates such as tin, copper, or ceramic laps, where diamond or aluminium-oxide preparations are the conventional choice.

Suitable Gemstone Species

GreenWay polish is intended primarily for softer gemstone species — broadly those falling in the lower-to-middle range of the Mohs scale. Minerals such as calcite, fluorite, apatite, and similar species with hardnesses roughly between 3 and 6 respond well to the compound's abrasive level and to the gentle, yielding surface of the composite lap. Harder species — corundum, spinel, topaz, and chrysoberyl — generally require more aggressive polishing media and harder lap materials to achieve comparable surface quality in a reasonable time.

Position in the Lapidary Workflow

GreenWay polish is a finishing medium, not a pre-polish or grinding compound. It is introduced after the stone has progressed through coarser grinding stages and a pre-polish step that has already removed the majority of sub-surface damage. Applying the compound to a properly prepared GreenWay lap, the lapidary works each facet or cabochon surface until reflected light shows a uniform, scratch-free finish. Contamination from coarser grits is the most common cause of failure at this stage; thorough cleaning of both the stone and the lap between stages is therefore essential.

Trade Context

GreenWay polish occupies a niche within the hobbyist and amateur faceting market. Professional cutters working with high-value rough typically favour dedicated diamond polishing compounds on metal laps — particularly tin-alloy or lead-alloy surfaces for faceting — or aluminium-oxide and cerium-oxide preparations on ceramic or wooden laps, because these combinations offer greater tactile feedback, faster material removal, and more predictable results across a wider range of species. For the hobbyist cutting softer ornamental material, however, the GreenWay system offers a convenient, self-contained solution in which the lap and compound are designed to work together, reducing the variables that can frustrate less experienced cutters.
