Mirror Polish — The Standard High-Reflectivity Metal Finish
Mirror Polish — The Standard High-Reflectivity Metal Finish
A polished metal surface that returns a clear reflection, the default for fine jewellery
Mirror polish is the surface finish standard for fine jewellery in platinum, white gold, yellow gold, and rose gold: a smooth, highly reflective surface produced by progressive abrasion through finer and finer grits, culminating in buffing with rouge, diamond compound, or equivalent fine polishing media. The finish is functionally synonymous with high polish in the trade and is the default choice for prong settings, bezels, smooth bands, and any surface where the metal's lustre is intended to read as a finish in its own right.
How it is achieved
The polishing sequence begins with abrasive grits in the 200-to-400 range, removing milling marks, casting texture, or file marks. Successive stages step down through 600, 1000, 1500, and finer grits, each removing the abrasion patterns of the previous stage and producing finer and finer surface features. The final buffing is done with cloth or felt wheels charged with rouge (iron oxide), tripoli (silicate-based compound), or diamond paste, depending on the metal and the desired final finish.
Platinum requires its own polishing regime distinct from gold; the metal's mechanical properties make it slower to polish but capable of taking and holding the brightest finish of any commonly used jewellery metal. White gold, yellow gold, and rose gold each respond slightly differently to the polishing sequence, and experienced bench polishers adjust their approach accordingly.
Use and limitations
Mirror polish is the default in fine bridal and formal jewellery. The finish maximises the metal's lustre and provides a striking foil to set stones. For everyday-wear pieces, mirror polish has the disadvantage that scratches and small surface marks are highly visible against the reflective base, and a piece with a mirror-polished surface will require periodic re-polishing to maintain its appearance. Brushed, satin, or matte finishes are more forgiving of daily wear and are increasingly chosen for casual or contemporary pieces.
Mixed-finish work — a mirror-polished bezel against a brushed band, for instance — is a common contemporary design choice that combines the visual impact of polish with the wearability of a textured surface.
In the trade
Skyjems' default for fine bridal and formal jewellery is mirror polish, executed to the highest standard the bench polisher can achieve. For everyday-wear pieces, we are happy to discuss alternative finishes and to advise on the long-term maintenance implications. Re-polishing service is part of standard maintenance and should be expected periodically across the life of any mirror-polished piece.
