What to Do If a Diamond Falls Out

1. Stop wearing it. One empty seat means the metal around it moved. The next stone is often already loose.
2. Bag it. Put the piece in a zip bag or ring box so any other loose stone stays inside.
3. Do not press the prongs back yourself. Pliers crack prongs and chip girdles.
4. Write down where you were. Car, gym, sink, bed. It narrows the search.
5. Take photos of the empty seat and the whole piece. Insurers and jewelers both ask for them.

Small diamonds are easier to find in the dark than in daylight. Turn off the lights and sweep a flashlight low across the floor. A diamond throws back a sharp flash, while glass and sand look dull.

• Floors: put a thin sock or pantyhose over the vacuum hose with a rubber band, then vacuum slowly. The stone gets caught on the fabric instead of the bag.
• Sinks and showers: stop the water. The U-shaped trap under the sink holds heavy items. A plumber or a bucket and wrench gets it out.
• Clothes and bedding: shake them out over a white sheet.
• Cars: seat rails and cup holders catch most of what falls.

Melee, the small stones in pavé, are often under 0.02 carat, about 1.5 mm across. If the missing stone was that small, do not spend hours: a matching melee stone is a routine bench job.

Cause	What you see	Common in
Worn prong tips	Flat, thin prongs; stone catches on sweaters	Solitaire rings worn daily
Bent prong from a hit	One prong lifted or pushed sideways	Rings worn at the gym or work
Worn beads in pavé	Stones that rattle when you shake the piece	Iced chains, pendants, bracelets
Glue instead of metal	Clean, empty holes with no sign of a bead	Cheap iced jewelry
Twisting stress	Several stones gone in one row	Flexible iced chains and tennis-style pieces

Iced pieces flex with every move. A diamond necklace like the Round Lab Diamond Necklace 18.48 ct, 14K Yellow Gold ($6,500) or a diamond Cuban chain bends at every link, and that motion slowly works on the beads. See diamond Cuban link chains and tennis chains for how each style is built.

A replacement has to match four things: size in millimeters, shape, color and the look of the cut. For a center stone, also match origin. A lab diamond should be replaced with a lab diamond, a natural with a natural, and the FTC requires sellers to disclose which one you are getting.

• Small pavé stones: matched by measuring the empty seat and the stones next to it. Color differences at this size are hard to see.
• Baguettes and fancy shapes: harder, because each one is cut to fit its spot. Expect the jeweler to cut or source one stone at a time.
• Center stones: if you have the grading report, the replacement can be matched to the same carat, color and clarity.

Before the stone goes in, the setting gets fixed: new prong tips, re-beading, or a new head on a ring. Setting a new stone in a worn seat just repeats the problem.

If you bought the piece from us and it arrives with a manufacturing defect, our policy gives you 7 days after receiving it to request a return. The piece must be unworn, in the condition you received it, with tags, original packaging and proof of purchase. Beyond that, all sales are final and we do not offer refunds.

Stone loss from daily wear is usually covered by jewelry insurance, not by a store policy. A scheduled jewelry policy or rider normally covers loss of a stone when the piece is listed with an appraisal. Read what a jewelry warranty covers to see the difference.

Once one stone is gone, the useful question is how many others are close behind. A proper check takes a few minutes and goes in this order:

1. Shake test. The piece is held next to the ear and tapped. Loose stones click.
2. Toothpick or tweezer test. Each stone is pushed gently from the side. A sound stone does not move at all.
3. Magnification. Under a loupe or microscope the jeweler looks at prong tips, beads and the walls of channels for thin spots, cracks and gaps.
4. Back view. Turning the piece over shows bent prongs and stones sitting crooked that you cannot see from the front.
5. Written list. A good shop writes down every loose or missing stone before quoting, so you know the full job and not just the one empty hole.

On a ring, the usual fix is retipping, which adds fresh metal to worn prong tips. On pavé and iced work, the fix is re-beading: pushing up new metal to grip each stone again.

• Shake iced pieces next to your ear once a week. A rattle is your early warning.
• Take rings off for the gym, yard work and the beach.
• Have prongs and beads checked once or twice a year if you wear a piece daily.
• Clean by hand. A home ultrasonic cleaner can shake out a stone that was barely holding on. Our guide to cleaning iced out jewelry shows the safe method, and how to clean diamond jewelry covers rings.
• Choose settings that suit how you live. Bezel and channel settings hold small stones more securely than open pavé.

For pieces built to be worn hard, look at how the stones are held before you buy. Our iced out chains, diamond pendants and iced out jewelry pages show the settings up close, and you can look at any of them under a loupe in our Miami showroom.
