Custom Jewellery Manufacturing Services With NDA
We have a responsibility to preserve our clients’ privacy, thus we are unable to reveal their identities or any other information about their operations.
Furthermore, we are constantly working to improve our solutions so that we can provide even more value to our clients in all capacities.
Your intellectual property rights are respected by us. A non-disclosure agreement (NDA) would be signed prior to the start of the manufacturing process. This is to ensure that your unique design is never shared with anybody else under any circumstances.

Recycled Gold and Silver
In our manufacturing plant, not a single piece of the metal strap would be thrown away. We make jewelry made entirely of recycled silver and gold by utilizing our production expertise. Metal scraps generated during the treeing process, for example, will be recycled back into the system and used to create other magnificent pieces of jewelry.

Gold Vermeil Jewellery
Gold Vermeil consists of a base metal onto which a layer of Gold is placed. We start off with Sterling Silver as the base metal, then the Gold (18ct. as a max) is applied through electroplating it onto the Sterling silver base, which results in them fusing together. The Gold layer has to be at least 2.5 Microns thick, which provides us with a luxury product made of a real gold layer.

Jewellery Manufacturing Services

Jewellery Design
Design tailored to your needs based on the samples that you provide or original sketches that we develop at your request.
We recognize that jewellery design is all about a spark of creativity. That’s why we accept any type of referenced data and information from designers, including CAD files, PDF files, hand-drawn drawings, and even spoken explanations with googled pictures. Our skilled artisans will turn your imaginative ideas into real works of art.

Jewellery 3D Design
CAD (Computer-Aided-Design) models that maximize quality, minimize the costs and realize your vision.
Our jewellery design team will take your ideas and turn them into reality, starting with basic napkin sketches. During the development stage, a variety of techniques will be employed, including hand drawings, CAD drafting, 3D printing, and modeling. Your design will be rendered in 2D and 3D models, and you may buy a prototype to test the quality and attention to detail before ordering in mass.

Jewellery Prototype
Traditional jewelry design techniques like hand sketching and drafting are still widely employed in jewelry manufacturing.
However, for a variety of reasons, we usecomputer-aided design (CAD) software tools to develop a unique jewelry prototype. A jewelry prototype may be easily reproduced using a computer-controlled production process by using a CAD model of a ring, bracelet, earrings, or other types of jewelry. This is simpler than traditional jewelry creation methods, which need a high level of competence in order to minimize mistakes and save time.

Jewellery Casting
The wax pieces are formed from the rubber molds created from the silver master in this phase. On the commercial wax injector machine, the rubber mold is installed. To make wax models for casting, molten wax is pumped into the mold cavity under pressure.

Jewellery Filling
Filling with precious instruments to fully achieve the desired product shape.
Filling is the process of removing any surplus metal from a piece of metal and smoothing off the surface. This step is required to ensure that each piece of jewelry is in the best possible condition.

Jewellery Stone Setting
Setting by expert craftsmen who excel in placing stones securely and efficiently.

Jewellery Polishing
Polishing in multiple stages in order to ensure the perfect finish for every piece.
Polishing, like filling, entails the employment of many materials to ensure that the object is polished properly. The goal is to make the metal shine and be free of blemishes, giving it a high-end appearance. High-speed polishing equipment and cleaning baths are commonly used.

Quality Control
Quality Control at every stage of production, followed by a final pre-shipment check.
Professional jewellers do not sell gold jewelry that has not been subjected to stringent quality controls. When everything is completed and the piece is declared done, a team of devoted specialists examines the jewel for any faults or blemishes.
