Considered answers.

A lab-grown diamond is pure crystallized carbon — atomically and optically identical to a mined diamond. The only difference is origin: instead of forming over billions of years beneath the earth, the stone is grown in a controlled environment over a few weeks, using either High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD) processes. Hardness, refractive index, density, dispersion, and chemical composition are all the same as a mined diamond.

Yes. Both the Federal Trade Commission (United States) and the Gemological Institute of America (GIA) classify lab-grown diamonds as diamonds — not simulants. They are not cubic zirconia, moissanite, or glass. A gemologist examining a lab-grown diamond uses the same vocabulary, the same 4Cs, and the same grading scales as for any mined stone.

Three reasons most of our clients give. First, value: lab-grown stones are typically 60–80% less per carat than equivalent mined diamonds, which allows a larger, finer stone at the same budget. Second, traceability: a lab-grown diamond's provenance is unambiguous, with no ethical questions about its sourcing. Third, environmental footprint: lab production avoids large-scale earth displacement and the water-intensive processes of mining.

No. Lab-grown diamonds do not cloud, yellow, or lose their light return with age. They are not coated. They are the same crystalline carbon they were the day they were finished, and they will continue to be — diamond is the hardest natural material known.

Our reserve is lab-grown, but yes — for custom commissions we also source natural diamonds on request, including specific stones a client may have already found or inherited. If your piece calls for a natural stone, tell us in your inquiry and we will quote the same considered process around it.

Every stone in the reserve carries a report from an independent gemological laboratory, almost always the International Gemological Institute (IGI) or, less often, the Gemological Institute of America (GIA). The report is a printed and digital record of the stone's exact carat weight, color grade, clarity grade, cut grade, measurements, and a unique serial number — often inscribed on the girdle of the diamond itself.

Both are recognized international laboratories. GIA originated the 4Cs system and is widely considered the most conservative grader; its reports often carry a small premium. IGI is the dominant grading authority for lab-grown stones and produces high-resolution digital reports. For lab diamonds the practical difference is minimal — we will provide either, and our recommendations are made on the stone, not on which lab issued the report.

Within one business day you'll receive a personal reply. We'll begin a short conversation about the occasion, the wearer, your stylistic references, and your timeline. We then propose a stone (or a small selection), share its certificate, and sketch a setting concept. Once the design is approved, we cast, set, and finish the piece. You receive it insured, in person where possible.

A typical commission runs four to six weeks from approved design to delivered piece. Stone selection and design refinement is usually one to two weeks; casting and setting takes another two to three; final polishing and inspection takes a few days. Rush timelines are possible for engagements and gifts on shorter horizons — please tell us your date in the inquiry.

Of course. Revisions are part of the design phase, and we expect them. Once the design is approved and we begin casting, structural changes are no longer possible — but we will not move into production until you are confident in the design.

We can take inspiration from any reference you provide, and we'll discuss what is and isn't possible given the stone you choose. We do not produce direct replicas of another house's work; we work toward the spirit of what you love, in a piece that's unmistakably yours.

Every commission is quoted individually. The price reflects the certified stone, the precious metal used (typically 18-karat recycled gold or platinum), the complexity of the setting, and any accent stones. A full quote is shared before any work begins, and the figure agreed at that stage is the figure on the final invoice.

We can arrange a complimentary at-home sizing kit, or guide you through a discreet way to measure a ring the wearer already owns. For surprise commissions, we always build in a free resizing within ninety days of delivery, so the initial fit doesn't need to be perfect.

Most rings can. Resizing depends on the band design — eternity-style and channel-set bands have limited adjustment range — and we'll tell you the range when we agree the design. The first resize within ninety days of delivery is complimentary.

Fully insured, signature on receipt, with discreet outer packaging. For domestic deliveries we use overnight courier; international shipments use a fully insured courier with customs documentation handled. Where possible we offer in-person handover.

Because every piece is made for one person, custom commissions cannot be returned for refund. We do, however, stand behind the work: a one-year warranty on craftsmanship, lifetime cleaning and inspection, and the complimentary first resize. If anything is not right, we make it right.

Diamonds are hard but the settings holding them are not. We recommend removing rings before sport, gardening, swimming in chlorinated water, and any task involving harsh chemicals. Clean at home with warm water and a soft brush; we offer complimentary professional cleaning and inspection for the lifetime of the piece.
