Bespoke

GROMOV emerald and diamond engagement ring

At GROMOV, bespoke is not a service we add to our catalogue. It is the gravitational center of the atelier - the discipline from which our signature language emerges. Each commissioned piece is an act of authorship: yours and ours, written together in metal and stone.

"Some objects are not bought. They are commissioned into existence - drawn, debated, refined, and finally carried." Valeriy Gromov, founder - GROMOV

This page is for collectors who want something the world has not yet seen. We do not reproduce other houses' designs, we do not chase trends, and we do not offer "customization" of stock pieces with engraving. Bespoke means we begin with a blank sketchbook, your reference, and a conversation that may last weeks before the first wax is even cut.

The Bespoke Process

Most bespoke pieces follow a four-phase rhythm. We can compress or expand this timeline based on the complexity of the commission, but the structure rarely changes.

From First Conversation to Final Object

1. Brief & Intent - We begin by understanding the why. What occasion, what person, what feeling. We ask about lifestyle, hand size, sleeve length, what jewelry you already wear and never take off. The brief is shorter than you expect, but more precise.

2. Sketches & Refinement - You receive 2-4 hand sketches with notes on proportions, stone placement, metal choice, and engineering trade-offs. Revisions happen in dialogue, not by silent email exchange. Most clients converge by sketch round three.

3. Stone Sourcing - Once design is locked, we present curated stones from sightholder partners and our private vault. Every stone arrives with full lab documentation (GIA, AGL, GRS as applicable) and is photographed against neutral grey for true color reading.

4. Production & Delivery - CAD review, hand-finishing in our atelier, hallmarking, and final QC. Production typically takes 4-8 weeks once stones and design are approved. Pieces ship insured worldwide.

Stones: The Soul of the Commission

For bespoke clients, we work primarily with three categories: white diamonds (D-F, FL-VS1, ideally Type IIa), unheated colored stones (Burmese ruby, Kashmir or Ceylon sapphire, Colombian emerald, Brazilian Paraiba tourmaline), and rare specimens (alexandrite, padparadscha, Mahenge spinel, Mozambique copper-bearing tourmaline).

Our living inventory of investment-grade D/FL stones is published on our FLAWLESS collection. Each is photographed, certified, and immediately available for commission. For colored stones, we present curated options after the brief is locked.

Materials We Work With

Platinum 950

Heaviest in hand, naturally white-grey, develops a noble patina, no plating ever required. Our default for important diamond work.

Palladium White Gold

Naturally white from alloy chemistry, no rhodium plating, low maintenance. The thinking man's white gold.

18K Yellow Gold

75% gold purity, rich warm tone, most balanced for daily wear and heirloom intent.

22K Yellow Gold

91.6% pure, ceremonial depth, soft to the eye and to the touch. Reserved for pieces that will not see daily abuse.

The Curated Vault: Ready for Bespoke

We maintain a permanent inventory of investment-grade stones and signature pieces ready for immediate bespoke commission. Browse the FLAWLESS collection to see our active D-color, Internally Flawless diamond inventory, all GIA-certified, all Excellent/Excellent in cut and polish, all without fluorescence.

The Philosophy Behind Bespoke

The market for fine jewelry is split into two halves. One half manufactures heritage at scale: thousands of identical pieces, sold as if each were singular. The other half makes things by hand, but with cynical pricing and design borrowed from the first half. We try to be neither.

Our bespoke practice is based on a simple bet: that there are still collectors who care more about the story of a piece than about its monogram. Who would rather own one object made for them than three made for the catalogue. Who understand that real value lives in restraint, in proportion, in the thing that is not there.

Frequently Asked Questions

What is the minimum budget for a bespoke commission?

We undertake complex, highly individual commissions. The budget for a bespoke project begins at $20,000 USD.

How long does the bespoke process take from start to finish?

Average timeline is 8-14 weeks. Design phase (1-3 weeks), stone sourcing (2-4 weeks for investment-grade), production (4-8 weeks). Complex commissions with rare unheated stones can extend to 6 months. We do not promise compressed timelines - real craftsmanship takes the time it takes.

Can I bring my own stone?

Yes. Many of our most meaningful commissions involve a family stone, an estate piece being reset, or a specimen the client has acquired separately. We provide a free assessment, lab certification if needed, and an honest opinion on whether the stone matches the design intent before we proceed.

Do you ship internationally?

Yes. We ship insured and signature-required to all major jurisdictions. We coordinate import documentation, ATA Carnets where applicable, and discrete handling. For trunk show clients in New York, Paris, Dubai, and Hong Kong, we deliver in person during scheduled visits.

What happens if I do not approve the sketches?

The first design phase includes up to four sketch rounds at no extra charge. If after four rounds we have not converged on a direction you love, you have the option to discontinue with no further obligation beyond the modest design retainer. This rarely happens because we calibrate during the brief, but it is your right.

Do you guarantee provenance and ethics on stones?

Every diamond comes with a GIA, IGI, or HRD certificate and is Kimberley-process compliant. Colored stones come with AGL, GRS, Gübelin, or SSEF reports as appropriate. Our partners are sightholders and direct-mine relationships in Sri Lanka, Mozambique, Brazil, and Madagascar. We do not work with conflict sources.

Can I commission a piece anonymously?

Yes. Many of our clients commission gifts with strict confidentiality. We sign NDAs, omit names from invoices and packaging on request, and coordinate delivery to neutral addresses. Discretion is part of the service.

How do trunk shows work?

Several times per year, Valeriy travels to New York, Paris, Dubai, and Hong Kong with active inventory and bespoke samples. These are private viewings by appointment, hosted in a hotel suite or private residence. Existing clients are invited automatically; new collectors join through the sourcing form on this page.
