For Designers & Makers

Collaborate

We work with independent jewellery designers, fashion houses, and custom makers who need access to exceptional stones with full provenance — on their terms.

What We Offer

Built Around How Designers Work

Custom Stone Sourcing

Tell us the specification — carat weight, colour grade, shape, origin preference — and we will source it directly from our network in Tanzania, Colombia, and Sri Lanka.

Exclusive Memo Access

Qualified designers receive memo terms on selected inventory, allowing you to design around a stone before committing. Standard 14-day memo period.

Provenance Documentation

Every stone comes with a complete documentation package — lab report, origin certificate, treatment disclosure — that you can share directly with your clients.

Wholesale Pricing

Established design partners receive trade pricing across our full inventory, with volume discounts available for ongoing relationships.

“The stone is the beginning of the design. We give you access to stones most designers can't source — and the documentation your clients expect.”
— Devan, Founder
