Codeeo delivers jewelry app development New York dealers and retailers can use to sell beyond the walk in trade. Many of the city's jewelers work from upstairs showrooms and booths around 47th Street, where buyers arrive by appointment and every sale involves trust, verification and a lot of back and forth. We build apps that handle that process properly: secure appointments, verified buyers, detailed stone information, deposits and follow up, all in one place.
New York adds its own layer of rules. Buying used gold or estate jewelry needs a city license, the state sets data security duties, and the city has a signage rule for businesses that collect biometric identifiers. We plan the app around all of them.

Inside the app
The Diamond District occupies a single block of West 47th Street between Fifth and Sixth Avenues in Midtown, and much of its business happens above street level, in offices and showrooms that only open the door to a known visitor. A customer looking for an engagement ring may visit four dealers in an afternoon, compare certificates on their phone and decide a week later. The dealer who keeps that customer's attention after they leave usually wins the sale.
The features below are aimed at that pattern: buyers who research heavily, want proof and expect to deal with a person. Estate jewelers and gold buyers have extra licensing duties, which the admin handles separately. We order the build around where your sales are lost today, which is often the follow up after a first visit. A dealer who answers a question about a stone within the hour, with the grading report attached, is far more likely to close than one who waits for the customer to call back.
Visitors book a showroom slot, confirm their identity and receive a time limited pass. Your door staff see who is expected and when, so the buzzer only opens for confirmed appointments and walk ins can request a slot from the lobby.
Safer showrooms and fewer unannounced visitors.
Each stone with its grading report, measurements, video and photos, searchable by shape, carat, color, clarity and price band. Lab-grown stones carry the qualifier the FTC Jewelry Guides require, and stones shared by partner dealers can be shown with clear availability.
Buyers compare stones properly before they visit.
After a visit, your salesperson sends the customer the stones and settings they looked at, with notes and a quote. The customer replies in the app, asks questions and can return to the same shortlist days later.
The conversation continues after the customer leaves 47th Street.
Deposits to hold a stone, balance payments, Apple Pay and Google Pay, all through a PCI DSS compliant processor. Wire transfer details are shown only inside the authenticated app, which reduces the risk of fake instructions sent by email.
Payments that are harder to intercept or spoof.
For dealers who buy used gold, silver, platinum or estate pieces, the app captures the seller's details and a description of the metal and stones for each purchase, kept in English as the city's secondhand dealer rules expect, ready for inspection.
Purchase records complete before the item reaches the safe.
Customers choose a setting for a stone they bought from you, or bring an heirloom stone for a new mount. CAD renders, approvals and production updates run through the app, so the setter and the customer always see the same version.
Custom work signed off in writing at each step.
Collection at the showroom with identity checked, or insured shipping with signature required to addresses across the five boroughs and beyond. The customer follows every step in the app.
High value orders reach the right person.
Appointments, shortlists, deposits, memo goods and purchase records in one place, with permissions that keep sensitive identification and pricing visible only to those who need it.
The whole showroom works from shared information.
Ring cleaning and prong checks, appraisal updates for insurance, and anniversary reminders customers choose to receive. Each one brings a buyer back to the dealer they trusted the first time.
A first sale turns into a long relationship.
New York buyers and visitors speak dozens of languages. Product details, booking screens and notifications can be offered in the languages your salespeople already use with customers, such as Spanish, Russian, Hebrew or Mandarin, with each customer's choice stored on their profile. Grading terms stay consistent across every version.
Buyers read stone details in the language they think in.
Who this is for
New York jewelry businesses range from dealers trading stones with each other in Midtown to neighborhood stores in Brooklyn, Queens and the Bronx and vintage specialists in downtown Manhattan. Their customers include New Yorkers, commuters from New Jersey, Long Island and Westchester, and visitors from abroad who come to the city to buy. The four businesses below gain most from an app. What they share is a sale that depends on trust built over several conversations, which is exactly what a well designed app can carry between visits. Businesses selling mainly low value fashion jewelry usually do better with a strong online store first.
You sell mostly by appointment, often to first time buyers who are nervous about spending so much and anxious about being misled. A New York jewelry app that books appointments securely, shows certified stones with honest labeling and keeps the shortlist alive after the visit answers that anxiety directly. It also lets couples share a shortlist with each other before they commit.
Booking and shortlists are the usual first release.
Every piece is one of a kind, and you buy from the public as well as sell. The app needs individual listings with condition notes and provenance where known, holds for interested buyers and a separate, licensed buying workflow that records sellers and items as city rules require. We keep the buying records apart from the shop screens. Pieces bought from the public can move into the retail catalog only after your own holding and checking steps are marked complete in the admin.
Your customers walk or take the subway to you and come back for repairs, batteries, gifts and family occasions. The app works as a loyalty card, repair tracker and gift list, with reminders for the dates customers save. Notifications in the languages your neighborhood speaks make it useful to more of your regulars. Parents can also set up a shared gift list so relatives know a ring size or a preferred metal before a birthday or graduation.
Loyalty and repair tracking bring regulars back.
Trade between dealers moves fast and depends on trust. A gated trade app shares your stone list with approved partners, records memo goods, tracks returns and keeps a dated history of every offer. Verified accounts only, with pricing set per partner. When a stone is sold elsewhere, it is withdrawn from every partner's view at once, which avoids the awkward call where two dealers think they hold the same goods.
How we work together
Codeeo does not have an office in New York. The team of 80+ is based in Dubai, Riyadh and Karachi and works with US clients remotely, so discovery, design reviews and sprint demos all happen over video call, followed by written notes. You can start with a fixed scope first release, continue on a monthly retainer, or bring in a dedicated team for a bigger program. Across the UAE and the US we have delivered 200+ projects, rated 4.7 from 23 Google reviews.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
Cross platform React Native or Flutter for most dealer and retail apps, native code when 360 degree stone video or 3D settings need it, and a secured cloud backend built around the inventory tools your business already relies on.

It depends on the first release and the systems behind it.
A booking and shortlist app for one showroom, connected to an existing inventory list, is a modest build. Adding loose diamond feeds from partner dealers, deposits, custom settings and a licensed buying workflow makes it larger. The clarity of your stone data and the number of integrations matter most. We agree the scope in discovery and put the milestones in writing, so timing is a commitment we can both check. If you want the app live before a busy season such as the holidays or Valentine's Day, we plan backward from that date and agree what can wait.
