Platinum Jewelry Casting Service

At Lukas Casting House, we understand that for independent designers and boutique brands, every casting is a critical component of their reputation.

Platinum is difficult to work with, requiring extreme temperatures and specialized equipment that many general shops avoid. We have built our Los Angeles workshop specifically to handle these high-heat challenges. Our focus isn’t on mass-market volume, but on the precision required for small-batch production and custom high-end pieces. We treat your wax models with the respect they deserve, ensuring that the transition from digital design to physical metal is seamless.

By partnering with us, you gain access to a dedicated casting team that functions as an extension of your own studio, providing the technical reliability you need to scale your collections with confidence.

Casting platinum is a science of timing and temperature. Because platinum solidifies almost instantly, the window for a perfect pour is incredibly narrow.

At Lukas Casting House, we utilize advanced vacuum pressure casting technology to force the molten metal into the finest details of your mold before it cools. This industrial-grade approach eliminates the common issues of incomplete fills and surface pitting. We maintain a clean, controlled environment to prevent cross-contamination from other alloys, which is vital for the structural integrity of the piece.

Our master casters monitor every flask personally, adjusting protocols based on the specific geometry of your design. This hands-on oversight ensures that whether it’s a delicate micro-pavé band or a heavy statement piece, the metal is dense, uniform, and free of internal defects.

The quality of your finished jewelry starts with the alloy.

We exclusively use high-purity 950 Platinum, balanced with Ruthenium or Cobalt depending on the specific requirements of your design. This choice is deliberate: we want to provide you with a metal that is not only bright and white but also has the “workability” required for secure stone setting and a long-lasting mirror polish. Unlike white gold, our platinum alloys do not require rhodium plating and will never change color over time. This makes them the ideal choice for heirloom-quality pieces.

We understand that your clients expect durability, and our casting process maximizes the natural strength of the metal, ensuring that prongs stay secure and shanks resist the wear and tear of daily use.

At Lukas Casting House, we believe the best results come from collaboration. We don’t just take your files and press “start.”

If we see a potential issue with wall thickness, sprue placement, or stone seats in your 3D model, we speak up. Our goal is to ensure that your design is “castable” and production-friendly before the metal is even melted. This proactive approach saves you time, money, and the frustration of failed pours. We offer a full-cycle manufacturing journey: from initial CAD consultation and high-resolution wax printing to the final casting and finishing.

By housing all these steps under one roof in our Los Angeles shop, we maintain a tight feedback loop that guarantees quality at every stage of the process.

From a manufacturing standpoint, platinum offers advantages that justify its premium.

While white gold is harder in its raw state, it is also more brittle and loses metal over time through abrasion. Platinum, however, is “displaceable” — it moves rather than wears away, making it far more durable for daily wear. In the workshop, this means stones are held more securely, and the metal can be refurbished many times without losing its mass.

We help our partner brands navigate these technical differences, providing the data they need to explain the value of platinum to their customers. When you choose platinum casting at Lukas, you are choosing a metal that reflects the true luxury and longevity of your brand.
