Custom Engagement Rings DC designs custom engagement rings in Washington, DC for buyers who want the drawing before the decision: every ring starts with a consultation and a full computer aided design spec sheet carrying your stone measurements, band dimensions, and exact ring size, and our manufacturing partner builds the ring to that sheet only after you approve it. We work in person across the District and fully online for buyers who prefer it, and either way you see photographs and video of your actual stones before anything is set.
That order matters. Most ring regret comes from buying a picture. A stock photo cannot tell you how a band feels, how high a stone sits, or whether a size is truly right. Our process removes the guessing at every step. You see the design from six angles with its measurements printed on the page. You approve each stage before we move to the next one, and nothing goes to the bench until you say the drawing is the ring you want.
We build every style of custom ring from our DC consultation base, and the drawing process is the same for all of them. The styles below are ordered the way our buyers most often build them, starting with the largest projects.
A bridal set draws the engagement ring and the wedding band together on one sheet, so the band sits flush against the ring from the first day with no gap and no later compromise. Our pear halo set further down this page was drawn exactly that way, two pieces planned as one.
Buyers who want the rarity story choose a natural center stone, and the drawing process protects that larger spend: the spec sheet fixes every measurement before the stone is set, and photographs of the actual stone are approved before manufacture begins.
Lab grown diamonds carry the same physical and chemical makeup as natural stones and typically allow a larger or higher grade stone at the same budget. Most custom buyers nationally now choose lab grown, and most of our DC designs are drawn around one.
A halo rings the center stone with small round diamonds that add presence and light from every angle. On the CAD sheet the halo is drawn at true scale, so you see exactly how tight it sits and how much of the center stone it frames before it exists in metal.
Three stone designs carry a center stone with a matched stone on each side, often read as past, present, and future. The sheet lists all three stones by millimeter and weight, and the side stones are photographed with the center so the match is judged as a set.
The quiet classic: one stone, one polished band, and nowhere for a weak stone to hide. Emerald cut solitaires are a DC favorite, and because that cut shows its interior plainly, the stone photographs at the selection step carry the whole decision honestly.
Sapphire and aquamarine centers give a ring color no diamond can imitate, and several of our factory stone photographs show the blue ranges we source. Colored centers are drawn with the same spec discipline and priced in the same open way.
Milgrain edges, tapered bands, and elongated stone shapes are all drawing decisions. Vintage inspired designs are drawn at true scale on the sheet, so the older character you want is visible in the measurements before the bench work begins.
Some of our most meaningful projects never start from zero.
Many DC buyers arrive holding something: a grandmother diamond in an old setting, or a ring that carries family meaning but not a style she would choose today. The consultation starts with measuring and grading the stone honestly. The family stone then goes onto the CAD sheet at its true measurements, the new setting is drawn around it, and you approve the complete design before anything is touched. Buyers keep the history and lose the compromise.
A band added later rarely sits right against a ring it was never drawn with. We draw matching bands for rings we built and for rings bought elsewhere, measuring the existing ring and drawing the band to sit against it properly.
Second rings and anniversary redesigns run through the same five step process, often with larger stones and bolder drawings than the first ring allowed. The spec sheet keeps the ambition honest and the budget visible.
The case studies below show how a design is documented before it is made. The first two are real designs from our bench, drawn, specified, and carried through to finished rings. The third shows a classic direction many DC buyers request, documented in the same format with figures from researched Washington area retail for the same specification.

Every measurement printed where the buyer can read it.

Cast, set, and polished, then checked against the sheet before delivery.
Center stone: oval, 14.00 by 9.50 millimeters, approximately 5.00 carats. Side stones: 24 round stones of 1.70 millimeters, 0.5040 carats in total. Band: 1.7 millimeters thick, 3 millimeters across the shank. Stone height 8.5 millimeters. Drawn for US size 5.
Story: the drawing promised a large center stone with light returning from every angle and a band that splits the weight visually, so the ring wears elegantly rather than heavily. The finished ring on the hand is the drawing kept.
Turnaround: inside the standard four to six week window from CAD approval.
Final price: a comparable specification quoted through researched DC retail channels runs $7,800 to $11,500 in lab grown and well beyond that range in natural diamond.

Oval split shank engagement ring, Capitol Hill, September 2026, $9,400 ballpark. Drawn at 14.00 by 9.50 millimeters with 24 side stones and delivered inside five weeks of CAD approval. The buyer perspective that stays with us: seeing the finished ring match the drawing line for line ended the worry that custom meant uncertain.

Pear halo bridal set, Georgetown, August 2026, $13,600 ballpark. Drawn as one set at 34 stones and 5.85 carats combined so the band sits flush. The buyer perspective: approving the set as a single drawing made the wedding band a decision finished a year early.

Emerald cut solitaire, Dupont Circle, September 2026, $7,900 ballpark. A single stone on a polished band where the stone photographs carried the decision before manufacture. The buyer perspective: judging the actual stone on screen, calmly, beat squinting at a stone under store lighting.
Tell us the style you have in mind, the date you are working toward, and the budget you want to respect, in person here in the District or by video call. Bring photographs, screenshots, a family stone, or nothing at all.
We translate the direction into a full CAD drawing with rendered views and a printed spec sheet. You review every angle and every number, on paper with us or on a shared screen call. Revisions happen here, while the ring is still lines on a screen, and changes at this stage cost nothing.
In person sizing happens at the consultation. Virtual buyers receive a ring sizer kit by mail and confirm the size with us on a follow up call, with an existing ring measured as a cross check. The size goes onto the CAD sheet as a locked measurement before manufacture starts.
We source center stone options that fit the drawing and the budget, in lab grown or natural diamond and in colored stones where the design calls for them. You receive photographs and video of the actual stones and choose with your eyes open.
Our manufacturing partner builds the ring to the approved sheet: casting, setting, polishing, and quality checks against the same measurements you signed off on. The finished ring is delivered in person locally or by insured, tracked, signature required shipping, and checked against the spec sheet with you either way.
Metals: 14k and 18k gold in white, yellow, and rose, and platinum, drawn and priced by true metal weight rather than the drawing metal the CAD program defaults to. Stones: lab grown diamond, natural diamond, and colored stones including sapphire and aquamarine. Center shapes: oval, pear, round brilliant, emerald, cushion, marquise, radiant, and princess. Settings and details: solitaire, halo, hidden halo, three stone, split shank, cathedral, and bezel, with matched wedding bands drawn at the same time whenever the design calls for a set.
Two rings can share a shape name and wear completely differently, and the difference lives in measurements most catalog pages never print. Stone height decides how a ring lives day to day, meeting door frames and gloves or sitting low and calm. Band width and thickness decide comfort and presence. Prong style and count decide both security and look, from four prongs showing more stone to a bezel wrapping it in metal entirely. Our sheet prints all of these numbers, and the consultation walks through what each one does on an actual hand.
Standard custom work runs four to six weeks from CAD approval to delivery, and five to seven weeks in total for most designs once consultation and drawing time are counted. Buyers with a fixed proposal date should start as early as they can. At your consultation we will map your date against the process honestly, including room for the unexpected, and say so plainly if a design needs simplifying to protect the date. Honest planning inside the window avoids rush costs entirely, which is why we ask for your proposal date at the first conversation.
Custom does not have to mean the highest price in the room. It means the price goes where you point it. Your quote separates the three parts of a ring price, the stone, the metal, and the making, so you can move money where it matters. Nothing is buried inside a brand markup, and there is no mall rent or showroom payroll inside your price.
Based on researched Washington area pricing for comparable specifications, lab grown custom designs most often land between $2,800 and $7,500 complete. Lab grown stones now let buyers choose a visibly larger stone at the same budget, which is why this range carries most of our designs.
Natural diamond custom designs most often land between $6,500 and $18,000 complete, with large stone or complex bridal sets moving above that range by specification. The stone carries most of the number, and the itemized quote shows exactly where.
Four things move your number. Stone size and origin move it most. Metal comes next, with platinum above 14k gold and 18k gold above 14k. Complexity follows: a halo, a split shank, and a matched band each add stones and bench time. Timeline matters least when planning starts early. Your quote is itemized in writing before you approve the CAD for manufacture, and if a choice pushes the design past your budget, the drawing stage is where we adjust it together, not the delivery day.
The national average engagement ring purchase was $4,600 in 2025, and a well planned custom ring at that same level buys a larger, better documented stone through our process than the same money typically buys off a shelf.
Consultations and in person deliveries cover Capitol Hill, Georgetown, Dupont Circle, Logan Circle, Navy Yard, Columbia Heights, Adams Morgan, Tenleytown, and Chevy Chase in the District, along with Takoma Park, College Park, and Hyattsville just across the Maryland line, plus Alexandria and Arlington across the Potomac in Virginia, and our Maryland location pages cover the wider state from Bethesda and Columbia to Baltimore and Annapolis. Virtual consultations serve buyers anywhere, with the same drawing, the same stone photographs, and insured delivery. Proposal landmarks are part of many of our timelines, from the Tidal Basin in cherry blossom season to the rooftop views over the Potomac, and we plan delivery dates backward from the day you have circled, never forward from the day you found us.
Plan on five to seven weeks in total for most designs: consultation and CAD inside the first one to two weeks, stone selection next, then four to six weeks of manufacture and delivery after the drawing is approved. At your consultation we map your date against the process honestly and say so plainly if a design needs simplifying to protect the date.
Lab grown custom designs most often land between $2,800 and $7,500 complete, and natural diamond custom designs most often land between $6,500 and $18,000 complete, based on researched Washington area pricing for comparable specifications. Your quote is itemized in writing, stone, metal, and making as separate lines, before you approve the CAD.
The same way we do in person: the size is locked onto the CAD spec sheet before manufacture. In person buyers are sized at the consultation. Virtual buyers receive a ring sizer kit by mail and confirm the size with us on a follow up call before the drawing locks, with an existing ring measured as a cross check. The finished ring is checked against that sheet before it is delivered.
Yes, and you should if anything feels wrong. Band width, stone height, halo shape, prong style, and metal color can all move while the ring is still a drawing, and changes at the CAD stage are free. Once you approve the sheet and manufacture begins, the design is locked, because metal and stones are committed to those measurements.
Both are real diamond, with the same physical and chemical makeup. Lab grown stones typically allow a larger or higher grade stone at the same budget, and most custom buyers nationally now choose them. Natural stones carry the rarity story some buyers want. We build in both, we price both in the open at your consultation, and the stone photographs let you compare with your own eyes rather than our opinion.
Your itemized quote is agreed in writing before manufacture. A deposit starts the bench work once you approve the CAD and your stone, and the balance is due at delivery when the finished ring is checked against its spec sheet. After delivery, tell us first about any wear question: prong checks and cleaning guidance are part of the relationship, and we route any bench work the ring needs and confirm cost in writing before it is done.
