From your stone
to a ring that
fits perfectly
We don’t pull a setting off a shelf and resize it. Every ring we make begins as a blank screen in CAD software and ends as a single cast piece of solid gold — engineered specifically for your stone, your finger, and your vision.
Most online jewelry works like a car lot. You choose from what’s already built. The settings come from factories in Asia, designed for average stones and average fingers. If your stone is deeper than standard, or your finger is narrower than the size chart assumes, the ring never quite fits right.
We work the other way. You tell us about your stone — its dimensions, its shape, its peculiarities. We design the setting around it in CAD, get your approval before we touch any metal, then cast it new using the lost-wax method that master jewelers have used for 5,000 years. The result is a ring that fits your stone like it was born there — because it was.
How your ring gets made
Six stages from first conversation to finished ring — and you’re involved at every meaningful decision point.
Tell us about your stone
The foundation of everything we build
The first conversation is about your gemstone — not your budget, not your timeline, not your design ideas. The stone comes first because everything else — the basket depth, the prong height, the band width, the metal weight — flows from the stone’s specific dimensions and characteristics.
You don’t need to have a gemological certificate or know technical terminology. A clear photograph from above, the side, and at an angle, along with any measurements you have, is enough to get started. If you don’t have measurements, a local jeweler can measure your stone in under five minutes — and we’ll tell you exactly what to ask them to record.
- ◆Stone shape — round, oval, pear, cushion, radiant, emerald-cut, marquise, or freeform
- ◆Dimensions in millimeters — length × width × depth (depth is critical and often overlooked)
- ◆Stone type — sapphire, ruby, tourmaline, diamond, collector gem, or heirloom piece
- ◆Any existing certificate (GIA, AGL, or other) — helpful but not required
- ◆Clear photos from multiple angles
Share your vision
Your ideas, however rough, become the design brief
You don’t need to arrive with a finished design concept. Most of our customers arrive with a feeling — “timeless and simple,” “vintage and ornate,” “modern and architectural” — and we translate that into a concrete design direction. Others come with a photo of a ring they love and want us to adapt for their stone. Both are excellent starting points.
What we need to know: the metal (14k or 18k gold, in yellow, white, or rose), any style references or photographs, your finger size or how to determine it, and whether you have any specific elements you want included or specifically want to avoid. The rest we handle.
- ◆Metal choice — 14k or 18k gold; yellow, white, or rose
- ◆Style direction — solitaire, halo, three-stone, bezel, vintage, nature-inspired, architectural
- ◆Any reference photos of rings you love or dislike
- ◆Your finger size — we’ll provide a guide if you’re unsure how to measure
- ◆Any must-haves or must-avoids
You receive a detailed quote
Transparent pricing, no obligation
Within 48 hours of receiving your stone details and design direction, we send you a written quote with an itemized breakdown — the cost of the setting, the metal weight, the finishing work, and shipping. There are no hidden fees and no pressure to proceed.
The quote also includes a proposed timeline, any design questions or observations from our review of your stone, and a clear outline of the next steps if you decide to move forward.
CAD design and your approval
Your ring in three dimensions — before a single gram of gold is melted
This is where the ring begins to exist. We build your design in professional CAD software — every prong, every millimeter of band width, every surface angle modeled in three dimensions with your stone’s exact measurements as the foundation. The basket is engineered to hold your specific stone at the correct depth. The band is proportioned to your finger size. Nothing is approximated.
We then produce a photorealistic render showing your ring from multiple angles. This render is sent to you for review before we proceed. If anything looks different from your vision — a prong feels too heavy, the band looks too thin, or the profile sits too high — we revise it. Nothing moves forward without your written approval.
- ◆Full 3D model built from your stone’s exact dimensions
- ◆Photorealistic render sent from multiple viewing angles
- ◆Revisions included during the CAD approval stage
- ◆Nothing proceeds to production without your written sign-off
3D printing, casting, and finishing
Ancient craft, precision technology
Once you approve the design, the CAD file is sent to a high-resolution 3D printer, which produces a resin model of your ring in exact scale. The model is inspected for accuracy before the project proceeds.
The resin model is invested in a plaster-like material and placed in a kiln. The kiln burns out the resin, leaving the exact negative cavity of the ring. Molten precious metal is then introduced into that cavity, capturing the approved design.
The cast ring then moves through hand finishing: filing, sanding, polishing, alignment checks, and stone setting. Every prong and surface is inspected before the ring is prepared for delivery.
- ◆High-resolution resin model printed from the approved CAD file
- ◆Physical model inspection before casting
- ◆Lost-wax casting in solid precious metal
- ◆Hand finishing and polishing
- ◆Professional stone setting
- ◆Final quality inspection before shipping

What you can always count on
Our process is built for
specific kinds of buyers
We work especially well with customers who already have a gemstone, an heirloom, or a clear design direction.

- Style direction or reference photographs
- Finger size
- Desired completion date
- Approximate budget range
Rings that people remember
“The finished piece exceeded my expectations. The communication was clear, and the craftsmanship was beautiful.”
“I had an unusual gemstone that required a custom approach. Gems Unique designed the setting around the stone instead of forcing it into a standard mounting.”
“Seeing the CAD rendering before production gave me confidence. I understood exactly how the ring would look before it was cast.”
