Our Custom Services

Four Ways to Bring Your Vision to Life

We serve individual clients as well as jewelers and businesses seeking OEM & ODM customization, matching the level of service to the complexity of your project.

01 — Concept Customization

Give Us Your Idea, We'll Design It

Share a simple description or a rough sketch. Our designers capture your intent, factor in wearing scenario and sizing, then build 1:1 CAD models with multi-angle 3D renders — bringing your inspiration to life on paper before it ever reaches the bench.

02 — Haute Customization

A Dedicated Consultant for Life's Moments

For proposals, anniversaries and milestone gifts, you're paired with a dedicated jewelry consultant and a senior designer. Every detail — diamond selection, silhouette, setting technique, metal and surface texture — is tailored to your exact requirements.

03 — CAD Customization

Your CAD File, Reproduced to 100% Accuracy

Send us your CAD drawing and our experienced jewelers will reproduce it 1:1, with an extensive range of affordable loose diamonds to choose from. Dimensions, setting technique, finishing and polish are matched to your file across every detail.

04 — Inspired Recreation

Refined, Respectful Recreation

We respect intellectual property. Our inspired recreation service covers limited restoration of your own vintage jewelry, and original designs newly conceived with a reference piece as creative inspiration — never a direct copy.
