Production Process

From Design to Delivery

We handle CAD design, casting, sourcing, setting, polishing, and QC, delivering flawless, turnkey pieces.

CAD Design

CAD Design

Our engineering hub. We utilize the latest Rhino and MatrixGold software to transform sketches into high-precision 3D models. With our high-resolution 3D wax printers, we can move from a digital concept to a physical prototype

Stone Sourcing

Stone Sourcing

Our in-house gemologists bridge the gap between mines and the bench. We provide a vast inventory of conflict-free diamonds and vibrant gemstones, ensuring every stone meets your brand’s specific clarity and color requirements.

The Foundry (Casting)

Our casting department uses advanced vacuum-pressure casting machines to ensure zero porosity and high-density metal structures. We work with 9K–22K Gold, 925 Silver, and Platinum, maintaining strict purity through regular testing.

Master Setting

Master Setting

This is where your design gains its sparkle. Our master setters work under high-power Leica microscopes to ensure every prong is perfectly symmetrical and every stone is seated with 0.01mm precision for maximum light return and security.

Polishing and Plating

Polishing & Plating

This is the final transformation. Our master polishers use a multi-stage buffing process to bring out the natural fire of the precious metal. From the initial Tripoli rub to the final Rouge high-luster buff, we ensure a mirror-like reflection that defines luxury jewelry.

QC Process

QC Process

Quality is not just a final step; it is our obsession. After a piece has been polished and plated, it enters our independent Quality Control. Here, the piece is isolated from the production team and subjected to a final, unbiased audit to ensure it meets international luxury standards before it is cleared for dispatch.
