Websites that sell fine jewelry and diamonds.
Jewelry and diamond buyers judge craft before they read a word. We've built for a New York fine-jewelry manufacturer (Kismet Jewels, about 35–40% higher average order value) and a lab-grown diamond vendor with a live inventory system (C6LGD).

Why jewelry and diamonds need different websites
A jewelry site has to show craft, and a diamond site has to show accurate stock. Private buyers want confidence before they pay for something expensive. Trade buyers want speed, detail and current availability. One template rarely does both.
Where we've done this work
For Kismet Jewels in New York, we built a flagship site for a CAD-to-fine-jewelry manufacturer. For C6LGD, we built a live stock listing system for professional diamond buyers, so they see what is actually available.

Techmines didn't just redesign our website. They redesigned how we present ourselves to the world. Within 3 months of launch, our inquiry rate nearly doubled and our average order value increased by approximately 35–40%. This wasn't decoration. It was strategy.
The live diamond listing system they built handles real-time inventory in ways we couldn't imagine before. Clean, fast, and exactly what our buyers needed.
