When independent designers and jewelry brands need a reliable production partner, they turn to a contract jewelry manufacturer — a specialized facility that handles the technical side of production while the designer focuses on creativity and brand building. In Los Angeles, Lukas Casting House has established itself as a trusted contract jewelry manufacturer serving designers, emerging brands, and established jewelry companies across the US.
Whether you need a single prototype, a short production run, or a full-cycle manufacturing partner for your ongoing collections, Lukas Casting House delivers precision, speed, and consistency at every stage.
What Is a Contract Jewelry Manufacturer?
A contract jewelry manufacturer produces jewelry on behalf of designers and brands, using the client’s designs and specifications. Unlike retail jewelers or wholesale suppliers, a contract manufacturer works exclusively B2B — your designs, your brand, manufactured to your exact standards.
Contract jewelry manufacturing covers the full production cycle:
- CAD modeling and 3D rendering — translating sketches into production-ready files
- Wax printing and prototyping — creating physical samples before committing to metal
- Precision casting — pouring molten metal into molds to create raw pieces
- Stone setting — placing diamonds and gemstones with professional-grade precision
- Finishing — polishing, plating, and surface treatment to market-ready standard
A good contract manufacturer becomes an extension of your team — someone who understands your brand standards, protects your designs, and delivers predictable results every time.
Why Los Angeles for Contract Jewelry Manufacturing?
Los Angeles is one of the most important jewelry production hubs in the United States. The city’s jewelry district — centered around South Hill Street in Downtown LA — concentrates decades of goldsmithing expertise, specialty alloy suppliers, gemstone dealers, and precision equipment vendors within a compact geographic area.
For brands and designers based on the West Coast, partnering with an LA-based contract manufacturer offers decisive advantages over overseas production:
- Turnaround in days, not weeks — no international shipping, no customs delays
- Real-time communication — same time zone, same language, direct access to production staff
- Design protection — your CAD files and proprietary designs stay in the US
- Quality control — visit the facility, inspect pieces in progress, catch issues before they ship
- No large MOQ requirements — produce small batches without overseas minimums
For brands sourcing from China, India, or Thailand, lead times of 6–12 weeks are standard. At Lukas Casting House, casting turnaround is typically 1–2 business days.
Contract Jewelry Manufacturing Services at Lukas Casting House
CAD Jewelry Design and 3D Modeling
Our in-house CAD team works directly with your sketches, reference images, or existing files to produce precise 3D models ready for wax printing and casting. We offer design optimization for manufacturability — identifying potential issues with wall thickness, undercuts, or stone seat geometry before any metal is poured.
Supported file formats: STL, 3DM (Rhino), OBJ.

Prototyping and Wax Printing
Direct-to-wax additive manufacturing delivers sub-0.1 mm resolution, enabling rapid design validation before committing to a full production run. Paired with rubber mold creation, prototyping at Lukas gives you a reusable master for consistent batch production.

Precision Jewelry Casting
Our electric hammering casting system eliminates porosity without weight loss or metal shrinkage, reducing polishing time by up to 25% and minimizing precious metal loss. We cast across all major alloys:
- Gold casting — 10K, 14K, 18K, 22K in yellow, white, and rose
- Silver casting — sterling 925 and fine silver
- Platinum casting — high-density, low-porosity results
- Brass jewelry casting — cost-effective for fashion and bridge jewelry
- Lost wax casting — for complex geometries and fine detail
Stone Setting
Our stone setters work across all major setting styles — prong, bezel, pavé, micro-pavé, channel, and flush — for diamonds, sapphires, emeralds, and other precious and semi-precious stones. Every piece is inspected for stone security before leaving the facility.
Jewelry Finishing
Surface finishing is what separates a raw casting from a market-ready piece. Our finishing services include:
- High-polish finish — mirror reflectivity for fine jewelry
- Matte and brushed finishes — for contemporary aesthetics
- Rhodium and gold plating — for durability and color enhancement
- Jewelry polishing — from rough tumble to final hand finish

What to Expect When Working With Us
Step 1 — Submit Your Jewelry Design
Send us your CAD files, sketches, or reference images along with your metal specifications, stone requirements, and batch size. If you don’t have CAD files yet, our design team can develop them from your sketches.
Step 2 — Get a Quote and Approval
We provide a detailed quote covering casting, setting, finishing, and any design work required. No hidden fees.
Step 3 — Creating a Prototype (if needed)
For new designs, we produce a wax prototype for your approval before proceeding to metal. This step catches issues early and avoids costly rework.
Step 4 — Jewelry Production
Casting turnaround is typically 1–2 business days. Stone setting and finishing are scheduled immediately after casting is approved.
Step 5 — Quality Check and Delivery
Every piece is inspected before shipping. We offer a satisfaction guarantee — if a piece does not meet our quality standards, we recast it at no additional charge.
At Lukas Casting House, every contract manufacturing order is backed by our quality guarantee. We take full responsibility for the quality of every piece that leaves our facility.
