We design custom engagement rings in Rockville, Maryland, as Maryland Custom Engagement Rings, giving Montgomery County buyers an approved CAD spec sheet, photographs of their actual stones, and an itemized written quote before any ring is made, with every step available in person or fully virtual.
Rockville is the county seat of Montgomery County. Rockville Town Square stays busy from lunch through evening, Rock Creek Regional Park puts miles of green trail minutes from the Pike, and neighborhoods like King Farm and Fallsgrove give the city a settled, deliberate feel. Buyers here live near more jewelry counters than almost anywhere in Maryland, which is exactly why a documented custom process stands out. A showroom asks you to trust its inventory. We ask you to trust a drawing you approved.
Our Rockville consultations are local, sizing is handled in person or by a mailed sizer kit confirmed on a call, and the design is priced in the open as stone, metal, and making, with delivery in Rockville or by insured signature shipping.


The first Rockville project centers an oval stone of 14.00 by 9.50 millimeters, about 5.00 carats, secured by four prongs over a shank that divides into two arms beneath the center. Along those arms sit 24 round side stones totaling 0.5040 carats, and the drawing records a US size 5 with band thickness, shank width, and stone height all specified. Drawn for a buyer in King Farm, the project ran five weeks from CAD approval to delivery and ballparked at $6,900 in lab grown diamond. Its case note is presence per dollar: the split shank spreads the design across the finger, so the ring reads large while the metal line stays modest.

The second project answered a different Rockville brief, a complete set planned in one sitting. A pear shaped center of 14.00 by 10.00 millimeters and 4.91 carats is ringed by a halo of round diamonds, and the wedding band is drawn in the same report, shaped to sit flush against the engagement ring. The combined documentation counts 34 stones at 5.85 carats in total for a US size 7.5 finger, with the ring at about 4.50 grams and the band at about 2.40 grams in the drawing metal. Built for a buyer in Twinbrook, the set ran six weeks from approval to delivery, at a ballpark of $9,800 in natural diamond. Drawing both pieces together settled the wedding day pairing at the design table.
Rockville buyers tend to keep their rings a long time and wear them daily, so our consultations here spend unusual time on how a design behaves across decades. Stone height, band thickness, and prong style are all visible at true scale on the CAD sheet, reviewed across a table or on a shared screen call, and a buyer can choose a lower profile for a life of keyboards and lab benches, or a higher one for maximum presence.
The second Rockville habit is comparison, and we feed it honestly. Lab grown and natural options for the same drawing are priced side by side, with photographs and video of actual stones in both origins. Platinum and 18k gold are priced as their own lines, so the metal decision is a number, not a mystery.
| Metal | Wear character | Buyers who pick it |
|---|---|---|
| Platinum | Heaviest feel, keeps its white color without plating | Daily wearers planning decades of use |
| 18k white gold | Bright white with a slightly softer hand feel | Buyers who want gold with maximum alloy strength |
| 14k yellow or rose gold | Warm color that flatters warmer toned stones | Buyers matching family jewelry or warm skin tones |
The third habit is paperwork. Stone, metal, and making stay separable on the itemized quote from first sketch to final total, and a change at the drawing stage reprices itself in the open. Custom engagement rings in North Bethesda What a custom ring costs
Researched regional pricing for comparable specifications puts lab grown custom designs most often between $2,800 and $7,500 complete and natural diamond custom designs most often between $6,500 and $18,000 complete. In a county where showroom rent is baked into every counter price, the itemized factory direct quote shows its value quickly. A deposit at CAD approval begins production, and the balance is due at delivery.
We serve Rockville neighborhoods including King Farm, Fallsgrove, Twinbrook, Potomac Woods, and the West End, along with buyers in North Bethesda, Bethesda, Potomac, Kensington, Aspen Hill, Wheaton, and Gaithersburg, all through the same sequence, in person or virtually.
Plan on 4 to 6 weeks of manufacture after CAD approval. At the first meeting, in person or by video, we map your date against the stages ahead of it, and if a design needs simplifying to protect the date, we say so before any deposit is taken.
Most Rockville projects land inside the researched regional bands, lab grown designs most often between $2,800 and $7,500 complete and natural designs most often between $6,500 and $18,000 complete. Your own number is fixed early, agreed in writing before manufacture begins.
Yes, and many Rockville buyers do exactly that. Consultations run by video call, a sizer kit arrives by mail and the size is confirmed on a follow up call before the drawing locks, the CAD is reviewed on a shared screen, and delivery is insured, tracked, and signature required.
Send us the style you have in mind and the date on your calendar, and we will answer with consultation times. Your design will be drawn before it is made, your stones photographed before they are set, and your price itemized before you commit to any of it.
