How UNI’s API Became the Backbone of a Growing Diamond Business
This Italy-based buyer needed a better way to scale. They had already built an app to showcase stones to customers, but sourcing was still a manual, time-consuming process. Enter UNI’s API. With real-time access to UNI’s global inventory of over 2 million stones, they could instantly connect customers to the right stones, automate their sourcing, and keep service levels high without adding complexity. Since joining in early 2025, they’ve bought over 700 stones worth more than $500,000 through the platform, all in less than six months, and they’re just getting started.
Introduction
Based in Italy, this diamond buyer had already begun building a modern business long before discovering UNI. They created a custom app to showcase diamonds to clients and had started putting key supplier stock online. But sourcing was still manual, time-intensive, and limited by what they could manage alone. After the pandemic forced a shift away from traditional sourcing trips to Belgium, it became clear: they needed a solution that could help them scale, automate, and serve more customers, without losing control.
Challenges Before Joining UNI
Modern, But Manual
Before UNI, the buyer’s strategy was forward-thinking, but the infrastructure didn’t match. They built a customer-facing app with about 100,000 stones from core suppliers, but inventory updates were manual, pricing lacked market benchmarking, and every order involved back-and-forth with vendors.
Logistics Holding Them Back
The logistics, too, were complex. From shipping costs to sourcing delays, managing diamond purchases across suppliers required a hands-on approach that didn’t scale with the speed of their customers’ needs.
It was functional, but far from frictionless.
Experience with UNI
A Game-Changing Connection
They discovered UNI at the VicenzaOro show, and the value was immediately clear. The platform provided access to a vast global inventory of over 2 million stones, but what really stood out was the API. Despite being strictly B2B, the API was exactly what they needed to streamline their internal sourcing. It allowed them to connect UNI’s live diamond feed directly into their own app, so they could browse real-time inventory and manage sourcing efficiently, without needing to manually update listings or juggle supplier spreadsheets. Setup was quick and seamless, with minimal technical effort, proving that integrating the API isn’t just powerful, it’s easy.
Smoother Sales Flow
The workflow is simple but powerful: when a customer selects a stone in the app, the buyer uses UNI to secure the order. They remain in full control of the buying decision, while giving their customers a fast, transparent experience.
Bulk Projects Made Easy
The impact has been transformative. On one project requiring 200 stones, they sourced 130 directly from UNI. Fast access to inventory made it possible to fulfill the request without delay, and the ability to consolidate shipments through Malca-Amit dramatically reduced logistics costs.
Results That Scale
In less than six months, they’ve purchased over 700 stones totaling more than $500,000 in value. Their clients now get faster service, better options, and competitive pricing, and they’ve been able to grow without adding operational burden.
Conclusion
For this Italian diamond buyer, UNI isn’t just a platform, it’s the engine behind their entire operation. The B2B API turned their internal system into a live sourcing machine. The data tools gave them clarity and confidence in every price. And the logistics support ensured stones arrive quickly and reliably, without added costs.
It’s a modern diamond business, built on automation, speed, and control. And thanks to UNI, it’s only growing stronger.
