Consultation and Concept Development
We begin with your market, design direction, target material, quantity and timeline.
Our team reviews references, sketches and product requirements, then recommends a practical development route. Key commercial and technical expectations are clarified before design work begins.
02
Design and Prototyping
Concepts become technical CAD models and approval-ready samples.
Proportions, stone sizes, construction, logo placement and production feasibility are resolved through digital design. A sample allows you to review the physical result before bulk manufacturing.

Material Selection
Choose materials that match your quality, positioning and target cost.
Options include solid gold, 925 sterling silver, brass, natural and lab-grown stones, pearls and controlled plating finishes. Specifications are documented for consistent sourcing and production.
04
Precision Manufacturing
Approved designs move through coordinated production and skilled finishing.
Casting, assembly, stone setting, polishing, plating and related processes are managed against the confirmed sample and technical requirements.
05
Quality Assurance
Inspection checkpoints protect appearance, construction and repeatability.
We review dimensions, stone security, soldering, surface finish, plating color and final presentation. Findings are resolved before packing and shipment.
06
Customization and Branding
The finished collection carries your identity, not the manufacturer’s.
Add engraved or cast logos, custom finish standards, private-label packaging and repeat-order documentation. NDA support is available for confidential developments.
