Overview

What we built

What we did
  • Shopify app development
  • Theme sections
  • Diamond inventory integration
  • UX design

Customers choose a setting from a Shopify collection, pick a centre stone from live diamond inventory, then review the finished ring and add it to the standard Shopify cart.

The diamond search filters by shape, colour, clarity, carat, cut and budget, across natural and lab-grown stones. The selected diamond becomes a real Shopify variant, so checkout, payments and order management stay native.
