Engagement Rings

The most important piece you'll ever commission. We guide you through every decision — metal, setting, stone, and shape — to create a ring as unique as your story.

Wedding Bands

Worn every day, forever. We craft wedding bands in platinum, gold, and rose gold — plain, diamond-set, or engraved with something only the two of you would know.

Exceptional Materials,
Responsibly Acquired

Every stone and every metal we use is sourced through verified, ethical supply chains. We work exclusively with suppliers who can demonstrate conflict-free provenance and fair labour practices — because the story behind your piece matters as much as the piece itself.

Our gemologists hand-select each stone for colour, cut, clarity, and carat — whether you're after a flawless round brilliant diamond or a vivid Colombian emerald. If you have a stone in mind, bring it. If you need guidance, we'll find the right one together.

From First Idea
to Finished Piece

Our five-step process is designed to give you complete confidence at every stage — from the first sketch to the final handover.

01

Share Your Vision

Tell us everything — occasion, style, budget, timeline. Sketches, Pinterest boards, a single sentence, or a rough idea. Every commission starts from wherever you are.

02

Design & Sketch

Our craftsmen translate your brief into detailed hand sketches and 3D renders. You'll see exactly how your piece will look — and we refine until it's perfect — before anything is made.

03

Deposit & Begin

Once you approve the design, a non-refundable 40% deposit confirms your commission and covers materials and workshop time. Production begins immediately.

04

Final Sign-Off

Before the finishing stage begins, your piece is presented for final approval. The remaining 60% balance is settled here. Your feedback shapes the final result.

05

Delivered to You

Your finished piece arrives in our signature Treasure Box packaging with full certification, care instructions, and lifetime after-care support. Collect in person or via insured delivery.

Bespoke and custom pieces are non-refundable once production has begun. The 40% deposit is non-refundable upon design sign-off. Standard pieces are subject to our 7-day return policy. Full Terms & Conditions →
