18-Carat Gold Jewelry Manufacturing by CNC Machining
Combining jewelry-making tradition with technological precision: this is the core of our work in 18-carat gold.
Thanks to CNC machining, we manufacture custom-made or small-batch jewelry with an exceptionally high level of precision. 750‰ gold offers the perfect balance of brilliance, strength, and prestige. CNC machining ensures consistency, finesse, and creative freedom. Discover a new way to design your jewelry—more agile, more reliable, and more responsible.
Why 18k Gold (750‰) Is Ideal for Fine Jewelry
Why 18K Gold (750‰) Is Ideal for Fine Jewelry
18K gold is the benchmark in fine jewelry because it offers the perfect balance between purity, beauty, and durability—exactly what is expected from a piece designed to last.
An Ideal Gold Content
75% pure gold (750/1000).
18K = 18 parts gold out of 24, meaning 75% fine gold.
This ratio is high enough to ensure the value, brilliance, and prestige of gold, while retaining enough alloy to provide strength and durability.
A Perfect Hold for Gemstones
In jewelry, the metal must hold settings securely over time.
18K gold has the rigidity and elasticity needed to secure prongs, bezels, channels, pavé settings… without being brittle.
A Richer and Deeper Color
With 75% pure gold, colors (yellow, white, rose) remain warmer and more “noble” than in lower karats (14K or 9K), where the higher alloy content dulls or cools the tone.
A Global Standard in High-End Jewelry
18K is the luxury reference in Europe and many other countries. It is well recognized, retains resale value, and is expected by clients looking for fine jewelry.
A Perfect Balance
18K gold remains the perfect balance: precious, long-lasting, and suitable for both delicate designs and technical pieces.
In short: 18K gold is the ideal material for creating real fine jewelry—beautiful over time, strong enough for daily wear, and internationally recognized as a premium standard.
CNC Machining in Jewelry: Precision in the Mass and Cost Efficiency
CAM programming applied to CNC machining in 18K gold completely transforms the production process compared to traditional casting. First, it eliminates heavy fixed costs: no mold fees, no wax printing expenses. The process goes directly from the 3D file to machining, making it much easier to launch new models—even in small batches.
Next, CAM provides superior precision and repeatability: volumes are controlled to the micron, thicknesses are consistent, and details remain sharp without the variability of casting (shrinkage, bubbles, deformation). It also saves significant time: there are no intermediate steps (wax → tree → casting → breakout), resulting in faster, more fluid production—ideal for restocking.
Finally, CNC machining controlled by CAM offers unmatched creative flexibility: you can adjust a design, size, engraving, or technical detail without redoing the entire molding process. The result: more economical production in small series, better quality control, and the ideal solution for testing collections, launching capsules, or developing custom-made pieces in CoC-certified 18K gold. Milling, turning, and micro-machining complete our expertise.
Examples of 18K Gold CNC-Machined Creations
Possible CNC-Machined Creations in 18K Gold (CoC)
CNC machining allows the creation of 18K gold jewelry with remarkable precision and flawless consistency. This technology enables both the production of uniform collections and the crafting of unique pieces. Valued for its nobility, strength, and lasting brilliance, 18K gold is perfectly suited for CNC machining—enhanced by CoC traceability, ensuring the authenticity of the metal.
• Rings / Wedding Bands
CNC makes it possible to create rings and wedding bands with impeccable shapes: classic or modern lines, sharp facets, engraved textures, openwork or asymmetrical designs. Fine engravings (inside or outside) can be integrated, and a variety of finishes are achievable: mirror polish, brushed, satin, or CNC-hammered. The result is precise, comfortable to wear, and ready for stone setting or personalization.
• Pendants / Medals
For pendants and medals, CNC offers great creative freedom: clean reliefs, fine details, chiseled lettering, symbols, or 3D volumes. It is ideal for signature collections, personalized medals, and technical pendants requiring a high-end finish.
• Custom Bracelet and Necklace Components
CNC machining is also ideal for custom pieces:
-
Bracelet elements (links, central pieces, clasps, engraved plates)
-
Necklace components (connectors, charms, spacers, signature pieces)
This is a reliable solution for unique items, limited series, or full collections crafted with the same level of precision and quality.
MOQ (Minimum Order Quantity) and Flexibility in 18K Gold Production
For CoC-certified 18K gold, our workshops are designed to meet the needs of both brands and independent designers working with capsule or progressive collections.
We offer flexible MOQs, allowing for small series production starting at just 10–12 pieces per model. This flexibility makes it easier to launch new designs, test markets, or restock—without tying up excessive inventory.
You benefit from premium, well-controlled manufacturing with CoC traceability, while maintaining real commercial agility.
