Yes. Loose diamonds from a drawer, a broken ring, or a stone you never got around to setting can become a ring you actually wear. Because the diamonds are already yours, you pay for design and setting, not for stones: in my studio that typically runs $2,500 to $10,000+ depending on the design, with most single-stone projects between $2,500 and $5,000.
Pinterest's 2026 trend report found searches for “heirloom jewelry” up 45 percent (as reported by National Jeweler in January), and I'm seeing the same thing from the other side of the bench: people are opening jewelry boxes instead of shopping. If yours has loose stones in it, here is what I look at first and what it costs.
A note from Kate: these ranges reflect my studio's work. The only way to get an exact number is a consultation where I can see and measure your stones, and mine is always complimentary.
What It Costs to Turn Loose Diamonds Into a Ring
| What you're making | Typical price range (setting + labor) | Timeline |
|---|---|---|
| Classic solitaire from one loose stone (14k gold) | $2,500 – $3,500 | 3–5 weeks |
| More detailed setting for one stone (18k gold or platinum) | $2,500 – $5,000 | 4–6 weeks |
| Full custom: three-stone, cluster, or several stones combined | $5,000 – $10,000+ | 6–10 weeks |

What I Check Before I Quote Anything
Loose stones come with unknowns that a finished ring doesn't. Before I design around them, I confirm what they actually are, because a drawer of sparkly stones is not always a drawer of diamonds. Then I look at each stone's size, shape, color, and condition, and whether the stones match well enough to sit together in one piece.
One stone or several
A single larger diamond becomes a solitaire easily. A handful of smaller stones needs a design that makes them look intentional: a cluster, a three-stone ring, or a center stone framed by the rest. The more stones, the more hand-setting time, and that is where the price climbs.
Chips and wear
Stones that lived in old jewelry often have small chips at the edge from years of wear. I can usually design around them, with a setting that protects the damaged area. Sometimes a stone isn't a good candidate for a ring that takes daily knocks, and I'll say so. If chips are your worry, read Can a Chipped Diamond Be Recut?
The metal
Platinum costs more than gold, and 18k costs more than 14k. If budget matters, 14k white gold looks very close to platinum to the eye and costs less. I'd rather tell you that than sell you the pricier metal.
Whether the stones are worth a ring at all
This is the concession. Very small stones don't always justify a full ring. If you have a scatter of tiny diamonds, a pendant or a pair of earrings is often the better use, and it costs less. I'll tell you if a ring isn't the right answer for what you have.
What Loose Stones Can Become
A ring is the obvious answer, but it isn't the only one. A single oval diamond can sit on its side in a bezel and become something like my Oval Cut Diamond East-West Bezel Necklace, which you'd wear every day without worrying about knocking it. If you want a ring with presence, a curved gold dome like my Oval Cut Pale Blue Sapphire Dome Ring shows how a single stone can carry a whole design. These are made to order, so they show zero inventory in the shop, which doesn't mean they're unavailable. They're examples of the style, and your stones would get their own design.
The Reframe: The Expensive Part Is Already in Your Box
Buying a comparable finished ring new means paying for the diamonds and the setting. You've already got the diamonds. The stones were chosen for someone, often by someone who loved them, and they carry that history into whatever they become. You're paying for the new setting around them, not paying for diamonds twice.
How the Process Works
- Free consultation. Bring the stones or photograph them. We talk about the ring you picture wearing, and I give you a preliminary range.
- Design and CAD. You see a 3D rendering before any metal is cut. You can see as many CAD designs as you need; the first two are included, with a small charge after that.
- Fabrication. The setting is made, and your stones go in at the end.
- Delivery. You pick up in Santa Monica or I ship it, insured.

Questions People Ask Me
Do I need a GIA certificate?
No. If you have paperwork, bring it. If not, I can assess stones in person or from clear photos to start.
Can I use stones from more than one piece?
Often, yes. Matching them in size and color is the main challenge, and I'll tell you honestly how well they'll sit together.
Do I have to live near Santa Monica?
No. Consultations work virtually from anywhere in the U.S., so you can start from home.
