James Allen is jewelry company specialized in diamonds and engagement rings. Just like many other companies, they first started as an online business only, and then later decided to open their first physical showroom location.
Our firm has years of experience helping clients translating a brand concept into a real location: a store, a showroom, a pop-up...
In this case the space was extremely small but it was going to be a destination by appointment only. We decided to transform it into a precious jewelry box and we know the sales have been amazing since the start.

A retail store is open to walk-in traffic and designed to convert casual browsers into buyers. A showroom, particularly a by-appointment model, is designed for a different kind of transaction: slower, more personal, and higher in stakes. The space needs to feel exclusive and private, not busy or commercial. When Sergio Mannino Studio designed the James Allen jewelry showroom in New York City, the entire concept was built around one client at a time—every spatial decision, from the single large desk to the soft lighting, was calibrated for that intimate, one-on-one experience.
There is a point in a high-value purchase, especially for engagement rings and diamonds, when a customer needs to see and hold the product in person before committing. Brands like James Allen, Warby Parker, and Indochino have all followed this logic: build trust and volume online, then use a physical location to close the gap for customers who need a tactile, human moment before buying. The showroom doesn't replace the website; it completes it.
By being extremely selective. A small, well-resolved space reads as precious; a small, unfocused space reads as cheap. For the James Allen showroom, Sergio Mannino Studio chose a minimalist approach: a single desk, a central display case, a suspended screen, soft pink carpeting, and carefully placed lighting. Every element was chosen to make the client feel they had stepped into a jewel box. Restraint, material quality at key touchpoints, and attention to lighting do more for perceived luxury than size or complexity.
Lighting is first; jewelry is only as beautiful as the light that hits it, and the wrong lighting kills a sale before it starts. After that: surface quality (what the client sees and touches while examining a piece), acoustic comfort (a noisy environment breaks concentration and intimacy), and seating arrangement (the relationship between client and sales associate should feel collaborative, not transactional). The showroom addressed all of these within a compact, challenging space that was adjacent to a mechanical room.
Dramatically. Without walk-in traffic, you don't need a storefront strategy, a queue, or a browsing layout. Instead, every square foot serves the appointment: arrival, welcome, the presentation moment, the decision conversation, and departure. The space can be smaller, quieter, and more considered. It should feel like a private room, not a store. This also means the design investment goes further because you're optimizing for depth of experience rather than volume of visitors.
You identify what the digital experience does well and find the physical equivalent, then you fill in what the digital experience cannot provide. James Allen's website gives customers extraordinary detail: every diamond photographed in 3D, every ring configurable online. The showroom's job was to provide what no screen can: the weight of the stone, the sparkle under real light, the feeling of trying on a ring. The design supports that moment of physical discovery without trying to compete with or replicate the digital experience.
Smaller than most people expect. A by-appointment jewelry showroom doesn't need to accommodate browsing crowds; it needs to accommodate one couple, a sales associate, and a curated selection of pieces. The showroom operates within a compact footprint inside an existing office, and that constraint became an asset: it enforced the intimacy and exclusivity that the brand wanted to communicate. The right size is whatever allows the experience to feel personal and unhurried, with no wasted space pulling focus.
By removing friction and building trust. A well-designed showroom signals that the brand takes quality seriously, even before a single piece is shown. It creates the right conditions for the client to slow down, ask questions, and feel comfortable making a significant purchase. Specific design moves, such as limited seating for one party at a time, surfaces at the right height for examining jewelry, and lighting that flatters both the stones and the client, all contribute directly to conversion without any of them feeling like sales tactics.
Yes, and there are real advantages to it. A showroom embedded in an office or building without traditional retail frontage reinforces the by-appointment, destination-quality of the experience: clients feel they are being invited somewhere, not walking into a shop. The design challenge is isolation: creating a space that feels completely separate from its surroundings in terms of mood, acoustics, and finish. Sergio Mannino Studio solved this by treating the room as a self-contained jewel box, independent of the office context around it.
Firms that understand both brand strategy and the specific sensory demands of high-value retail are best suited for this work. Sergio Mannino Studio is a New York-based architectural branding firm with direct experience designing retail and jewelry environments, including the James Allen private showroom in New York City, a project that transformed a small, difficult space into a destination that strengthened the brand's reputation and supported strong sales from opening. The studio's approach treats spatial design, brand identity, and customer experience as a single system.
