Understanding condition grades in vintage jewelry

Wear is the gradual, gentle rounding and softening that comes from decades of being worn, handled and occasionally knocked. On a ring it shows as a slight thinning at the base of the shank and softened edges on the highest points of any engraving or texture. On a brooch it shows at the pin catch and the back plate.

This kind of wear is not a defect. It is evidence that a piece is genuinely old and has been used for the purpose it was made for. We describe it plainly, and we treat it as entirely separate from damage.

A piece that has survived 50, 100 or 150 years has almost certainly needed a repair at some point: a re-tipped claw, a replaced pin stem, a resoldered join, a strengthened hinge. Skilled, sympathetic repair work that matches the original construction is a sign the piece has been cared for, not a mark against it.

What matters is disclosure and quality. A repair should be mentioned plainly in a description, and it should be done in a way that respects the original materials and technique, rather than replacing hand-finished work with a rough modern equivalent.

Stones are sometimes replaced over a piece's lifetime, whether because an original stone was damaged or lost, or because an owner chose to upgrade it. A replacement is not automatically a problem, but it should be disclosed, and a well-matched replacement in period-appropriate cut and color affects value far less than a mismatched one.

A common warning sign is a stone whose cut clearly postdates its mount, such as a modern round brilliant sitting in claws shaped for an old European cut. This tells you a swap has happened, even if no one along the way mentioned it.

Re-shanking, where all or part of a ring's shank is rebuilt, is a legitimate and often necessary repair on rings that have been worn thin over many decades. It is more significant than a claw re-tip because it replaces more of the original metal, so we always state clearly when a ring has been re-shanked, in full or in part.

A shank that has worn to under roughly a millimeter at its thinnest point is at real risk of failure and should either be disclosed as needing this work soon, or already re-shanked and disclosed as such.

In general, we consider the following normal and acceptable for genuinely antique jewelry: light overall surface wear, a softened but still legible hallmark, one or two sympathetically executed old repairs, minor case or setting wear on the reverse, and small variations from perfect symmetry that reflect hand construction.

We consider the following more significant and always worth disclosing clearly: heavy re-polishing that has visibly altered original detail, multiple mismatched repairs, replaced stones of the wrong cut or color, enamel loss, and any structural weakness that would affect how safely the piece can be worn.
