We design custom engagement rings in Dupont Circle, Washington, DC, and as Custom Engagement Rings DC we give this most discerning of neighborhoods a process documented to the millimeter, with sizing done in person or virtually and every design approved as a CAD drawing before it is made.
Dupont Circle gathers around its fountain, where chess players, readers, and coffee drinkers treat the grass as the neighborhood living room. Massachusetts Avenue runs northwest as Embassy Row, all flags and stone facades, and nearby the Phillips Collection keeps some of the finest small rooms of art in the city. On Sundays the farmers market fills the side streets with people who inspect everything before they buy.
That habit of looking closely defines our Dupont buyers: readers, travelers, and comparison shoppers who arrive with saved photographs, pointed questions, and a clear dislike of being sold to. We built our process for exactly that buyer: a measured size, a printed spec sheet, photographs of real stones, and a quote with nothing folded inside it.


We drew this ring with an oval center stone of 14.00 by 9.50 millimeters at about 5.00 carats on four prongs, the band splitting into two arms beneath it, each arm lined with round side stones. The spec sheet counts 24 side stones totaling 0.5040 carats, records the band at 1.7 millimeters thick and the shank at 3 millimeters across, sets the stone height at 8.5 millimeters, and sizes the design for a US size 5 finger. Drawn for the Connecticut Avenue corridor, it ran five weeks from CAD approval to delivery. Ballpark price: $9,100 as drawn with a lab grown center stone. Our case note concerns the side profile the drawing predicted so exactly: bold from above, graceful from the side, a pairing catalog photographs rarely deliver honestly.

For a buyer on the Embassy Row side of the circle, we documented a bridal set centered on a pear shaped stone of 14.00 by 10.00 millimeters at 4.91 carats, held inside a halo of round diamonds, with the wedding band drawn in the same commission to rest flush against it. The CAD report totals 34 stones at 5.85 carats combined, the ring weighing about 4.50 grams and the band about 2.40 grams in the drawing metal, sized for a US size 7.5 finger. Turnaround ran six weeks from CAD approval to delivery. Ballpark price: $11,200 as drawn with a lab grown center stone. The case note is about restraint inside abundance: at this scale, the drawing stage is where band width gets tuned so the set reads elegant at dinner table distance.
We think the drawing is what this neighborhood actually buys. It prints stone dimensions, band width and thickness, setting height, total stone weight, and the measured size in one document, and invites revision while revision is free. Vintage flavored details this market loves, tapered bands, milgrain edges, and lower profile settings for lives spent on bikes and Metro platforms, can all be drawn and approved at true scale.
The rest of the process keeps the same standard, in person or virtually. Consultations and sizing happen in person or virtually: meet us in the District, or consult by video call, receive a ring sizer kit by mail, and confirm the size on a follow up call before the CAD sheet locks, with an existing ring measured as a cross check. Virtual buyers review the drawing with us on a shared screen call, and every buyer judges center stones from photographs and video of the actual stones before one is set. The quote is itemized as stone, metal, and making, a deposit follows approval, and the balance is due at delivery, in person locally or by insured shipping, tracked and signature required.
Cost follows three drivers, and Dupont buyers tend to interrogate all three, which suits us. The stone moves the total most, the metal follows, and complexity completes the figure. We frame it as we do at the consultation table: a premium purchase, specified once and correctly.

Yes, and the drawing is where that gets proven. Tapered bands, milgrain edges, and period flavored galleries are all drawing decisions, shown at true dimensions so a delicate look is never bought at the cost of a fragile ring.
Either in person at the consultation, or virtually: we mail a ring sizer kit, confirm the result together on a follow up call, and can cross check against an existing ring you measure for us. The size is locked onto the CAD sheet before manufacture, which removes the most common failure of custom orders entirely.
Most plan inside the researched ranges in the table above, with elongated stones and matched sets frequently pushing a design toward the upper part of its range, lab grown at $2,800 to $7,500 and natural diamond at $6,500 to $18,000. Your figure is set in an itemized quote before any commitment.
Send us the photographs you have saved and the date you are working toward, and we will answer with consultation times, in the District or by video call. The design will exist on paper before it exists in metal, ready for the closest inspection this neighborhood can give.
