Can You Use Your Own Gold or Diamonds for Custom Made Jewelry?

Yes to the diamonds. Sort of to the gold.

You want to use your own gold or diamonds for custom made jewelry, and you'd like all of it to count for something. It can. Just in two different ways.

Using Your Own Diamonds in Custom Made Jewelry

If you've got a diamond, we'll always consider it. A center stone from a family ring, a pair of studs, a few loose stones from an old cocktail ring. Resetting stones people already own into a custom engagement ring or pendant is a big part of our diamond remounting work.

"Consider" just means two questions. Will the stone suit the design you want? Will it survive being set? Most do.

What we check before setting your stone

Fifty years on someone's hand leaves marks, usually at the girdle, the thin outer edge where the prongs grip. GIA's guidance on diamond chipping notes that chips tend to start at the girdle or at a point, and that inclusions near the girdle make a stone more vulnerable. So we look for:

• Existing chips or nicks along the edge
• Very thin girdles, common on old European and antique cushion cuts
• Deep feathers (small internal cracks) running toward the edge
• Pointed shapes like pear, marquise and princess, where the tips need protecting

None of that's automatically a dealbreaker. It changes the design. A pear with a delicate tip gets a V-prong over it. You'll hear about it before anyone picks up a setting tool.

Your stone sets the measurements

Old diamonds are rarely standard sizes. A one-carat cut decades ago is often deeper and narrower than a modern one, so it won't sit right in an off-the-shelf mount. We measure your stone and build the CAD (the 3D computer model of your piece) around it. That's the best argument for going custom.

Using Your Own Gold: It Becomes a Credit

We don't melt customer gold into new custom made jewelry. Send it in and you get a credit toward your item instead. Here's why.

Old jewelry is rarely one metal. A ring stamped 14K may have been resized twice with lower-karat solder, and a white gold piece might be alloyed with nickel. Melt them together and the result is a guess. Re-melted scrap traps gas too, which shows up as porosity: tiny pits that only appear once the piece is polished. Sometimes in a prong. The part holding your diamond.

There's a legal side too. The FTC's Jewelry Guides govern how gold is karat-marked, and we stamp the karat inside everything we make. With fresh alloy, we know that stamp is right. With a mystery melt we'd be guessing, and we won't guess on something you'll wear for forty years.

How the gold credit works

Once it arrives, we check the karat, weigh it, and the value comes off the price of your ring, pendant or custom wedding band. We can't confirm that number until the gold's in our hands. Broken chains, odd earrings, old class rings. If it's real gold, it counts.

One honest note. If the metal itself is what you can't let go of, keep that piece whole. Her worn band in a keepsake box says more than her gold hidden inside a new casting. Some people do both: the stone goes into the new ring, the band stays in the box.

Sending Your Diamonds and Gold to Our Studio

You don't have to be in New York. We'll send you a free insured shipping label for your diamonds and gold. Local? Book a New York appointment and bring them to the studio at 2 West 45th Street instead.

If you're shipping:

1. Contact us for the label and a packing slip.
2. List every item on the packing slip. Every stone, every piece of gold.
3. Double-box it: a small padded box inside a plain outer box.
4. Hand it over at a staffed FedEx Office or Ship Center. Not a drop box.
5. Keep the receipt until we confirm it's arrived.

Everything that arrives gets logged against your project in writing.

Before You Send Anything

Lay everything out, take a few photos in daylight, and send them through our custom jewelry project form with a note on what's sentimental and what's scrap. Want to play with ideas first? Try our AI ring design tool.

Then we'll set up a call about budget and what you're sending. We don't quote before that conversation. With your own stones in the mix, a number without it would be fiction. Once you approve the CAD, your piece takes 4–6 weeks to make.

Frequently Asked Questions

Can I use my grandmother's diamond in a new engagement ring?

Yes. The Custom Jeweler resets family diamonds into new engagement rings regularly. We look at the stone first for chips or thin edges, measure it, and design the CAD around its exact size and shape. If anything about the stone changes the design, you'll know before it's set.

Will you melt down my old gold to make custom made jewelry?

No. The Custom Jeweler casts every new piece in fresh alloy, so the karat stamp is accurate and the metal is free of old solder and porosity. Your old gold isn't wasted, though. Once it arrives, we check its karat, weigh it, and apply its value as a credit toward your new piece.

What if my diamond already has a chip?

A chip doesn't automatically rule a stone out. Depending on where it sits, the setting can often be designed so a prong or bezel covers and protects it. In some cases a recut is worth discussing, though it costs a little weight. We'll walk you through the options before anything gets set.

Can I use my own diamond and trade in gold on the same project?

Yes, and it's one of the most common setups we see. Your diamond goes into the new design, and the gold from the old setting, plus anything else you send, becomes a credit toward the price. One package, one project, one conversation about the numbers.
