Sourcing Any Requested Shape

Have a unique pendant or signet ring design? We don’t just offer standard cuts. Whether your 3D CAD requires a flat Hexagon, a sharp Kite shape, a classic Cabochon, or a custom geometric shield, we will source pre-cut stones to your exact specifications to fit the metal base perfectly.

The 12-Month Birthstone Collection

We offer high-quality natural and simulated semi-precious stones perfectly color-matched for all 12 birthstones.

Precision-Machined Setting Capabilities

Because 316L steel is incredibly hard, the secret to a secure setting lies in the exactness of the metal cavity. We utilize advanced multi-axis CNC machines to carve precise seats into the steel block.

Precision Inlay Setting

Highly popular for men’s signet rings and minimalist pendants. We machine a cavity that perfectly matches the sourced stone’s dimensions. The flat-cut semi-precious stone is then secured using industrial-grade, water-resistant jewelry adhesive, sitting perfectly flush with the steel surface for a bold, seamless aesthetic.

Secure Bezel-Style Setting

A seamless rim of 316L steel completely encircles the gemstone. The stone is nested tightly within this custom-machined rim and bonded securely, protecting the stone’s fragile edges from daily impact.

AQs About Semi-Precious Stone Jewelry Manufacturing

Do you accept customer-supplied stones for setting processing?

No. To ensure the highest quality control and seamless production, we do not accept customer-supplied stones. We operate as a full-service, end-to-end manufacturer. We supply the premium 316L steel and source the natural gemstones from our own vast network to deliver a complete, retail-ready product.

Can I request stones in custom geometric shapes?

Yes! While we do not cut the stones in-house, we have a robust supply chain. You simply provide the design (e.g., a specific hexagon, kite, or shield shape), and we will source the stones pre-cut to your exact specifications to perfectly fit the 316L steel jewelry design.

How are the stones secured into the stainless steel?

We use a combination of precision engineering and premium materials. First, we use CNC machining to create a metal cavity that perfectly matches the dimensions of the sourced stone. Then, we secure the stone using industrial-grade, water-resistant jewelry adhesive. Because the fit is so precise, the setting is incredibly durable and secure.

Will the PVD gold plating tarnish around the gemstone?

No. Traditional electroplating often tarnishes around the gemstone because water gets trapped in the crevices. PVD (Physical Vapor Deposition) is different. It is a vacuum coating process that bonds 18K gold to the 316L steel at a molecular level. This creates an impenetrable, waterproof shield across the entire metal surface. It will not rust or turn green, even with daily exposure to water.
