What is the process for repairing a custom ring?

The answer depends on what's wrong. But I'll give you the honest version most jewelers won't: about 60% of the repair work that comes across my bench could have been avoided with better initial construction. So let me walk you through how it actually goes, from a loose stone to a snapped shank, so you know what to expect before you hand over your ring.

First: the evaluation. You bring it in, I put it under a microscope - that's a stereo microscope at 10x to 40x, not a loupe, because I need to see the full picture. I'm looking for hairline cracks in the metal, worn prong tips, a girdle that's been chipped by a setting that was too tight. I'll flex the shank gently to check for fatigue cracks. I'll check the stone's security with a wooden point - if it rocks in the setting, that's a problem. I'll also weigh the ring and note the stamp, because a ring stamped 14k that weighs less than it should? Either it was cast too porous or it's been filed down from previous repairs. Both matter for the quote.

The quote itself. I don't give a flat number over the phone. I tell people it's in a range: retipping four prongs on a platinum setting runs about $120 to $180. A full head replacement on an engagement ring - cutting off the old setting, casting a new one, setting the stone - is $350 to $500. Resizing a plain shank up or down one size is usually $65 to $95. A full shank replacement, where the ring is literally broken in half and rebuilt, starts around $400 and climbs with the complexity of the setting. If your ring has channel-set diamonds along the shank, the price goes up because each stone has to come out and go back in. Those are real numbers from last quarter. They vary by market, but they're a starting point.

Once you approve the quote, the actual work. I'll give you the sequence for the most common repair I see: a loose center stone in a four-prong setting.

1. Stone removal. I don't always have to take the stone out, but if I'm retipping or replacing a prong, I do. The stone goes into a labeled stone paper packet, then into a plastic case. I photograph it first, because if it chips in the process - and that happens, maybe one in two hundred times - there's a record of its condition beforehand.
2. Metal work. If the prongs are just worn, I file them back to clean metal and add new gold or platinum using the same alloy as the original - 18k yellow on 18k yellow, not some random mix. I use a laser welder for this most days, not a torch, because the heat is localized and won't affect the stone or the surrounding metal. For a full prong replacement, I cut the old one off, cast a new one to match, and solder it in.
3. Stone resetting. The stone goes back in. I adjust the prongs with a pair of fine pliers and a pusher - not a hammer, not brute force. The prongs should be snug against the girdle without pinching. A correctly set diamond will rotate under pressure but won't wobble.
4. Finishing. I file the prong tips round, then sand them with progressively finer grits - 400, 600, 1200, then a trip to the tumbler with steel shot and burnishing compound. For white gold, it gets rhodium plated last. For platinum, I do a final polish with a mizzy wheel and rouge.
5. QC. I ultrasonic clean it, steam it, check it under the microscope again, and flex every prong with a wooden point. Then I wear it for an afternoon - literally put it on my own finger - because nothing reveals a rough edge or a prong that catches on fabric like wearing it.

Timeline. A simple retip is one to three days. A resizing is three to five, unless the ring has pave stones, then it's a week. A full head replacement with the same stone is one to two weeks. If the ring needs to go to a specialist - a hand engraver, or someone who replaces antique platinum work - add another week. Anyone promising a same-day turnaround on a complex repair is not doing the job correctly.

The thing that surprises most clients: the ring will not look identical afterward. It will look better, if I've done my job. But the patina gets removed during refinishing. The edges will be sharper. The rhodium on white gold will be fresh. Some people love that; some people want the worn-in look preserved. If you're the latter, tell your jeweler before they start. I've had clients cry over a ring that came back too shiny. That's not dramatic - that's a ring with memory.

One last thing. A repair is only as good as the jeweler's willingness to say no. I've had rings brought in that were so thin from years of resizing that any repair would be a temporary fix, maybe six months before the next break. I tell those clients the truth: put the ring in a box and commission a new one cast from the old one as a model. It's not what they want to hear. It's what they need to hear.
