Our Materials

Stones and Metals We Work With

Every setting is built around the stone — selected for cut, clarity, color and the way it catches light in daily wear.

Moissanite

High refractive index and strong fire, second only to diamond in hardness, available colorless and in colored tones.

Lab-Grown Diamonds

Same physical, chemical and optical properties as mined diamonds, with consistent clarity and an ethical story.

925 Sterling Silver

Durable 92.5% silver alloy finished in rhodium, gold vermeil or rose gold tone, built for daily wear.

What Buyers Say About Working With Us

Our third reorder from this supplier. Quality has stayed consistent across batches and packaging protects the pieces well. Would like slightly faster lead times during peak season.

We developed a small private-label line with the team. They followed our reference design closely and shared photos before production finished. Good communication throughout the run.

We ordered a mixed batch for our boutique. The samples matched the catalog photos and the workshop kept us updated on lead time. Helpful for a small retailer testing a new supplier.

I ordered this after reading the materials description carefully, and what I received matched it. The finish is even, the stone is securely seated, and the packaging protected it during shipping.

This is a lovely everyday piece. It sits comfortably and the design looks more expensive than the price point suggests. Communication about the order was clear from start to finish.

Happy with the purchase. The detail in the setting stands up to close inspection, and the piece feels balanced on the hand. I would consider another design from this workshop.
