Jewerly Manufacturing in Thailand

Complete jewelry manufacturing solutions in a hassle free, customer friendly environment.

Our services are designed mainly for jewelry designers, jewelry creators, boutique stores and Brands willing to develop and produce lines of jewelry products. We manufacture mainly Gold and high end Silver jewelry, but productions using other metals are not excluded as long as the projects are intended for high quality products.

A large variety of materials is available to be incorporated in very fancy designs. We outsource specialized tasks from independent craftsmen qualified to handle materials like mother of pearl, leather, stingray skin (galucha), wood, enamel, etc.

Our secret to bring the best finished product quality at low price is to keep unnecessary expenses as low as possible. For this reason we do everything in house except for casting and difficult pave settings. These tasks require an important investment and specialized workers which are not always justified for a custom jewellery manufacturer and which are pushing a factory to produce quantity instead of quality.
Our casting is very well handled by a specialized casting factory guarantying metal purity on large orders.

We accept to manufacture singles pieces designed for a specific single stones bought from us or provided by our customers together with a certificate allowing further verifications after setting is completed.

We are able to cut gemstones to fit in the settings produced in large quantities, saving our customer the hassle about sizes and shrinkage problems in jewelry production. Most of the time adjusting both the stones and the settings "on the fly" is the best solution to limit rejections.
In addition to manufacturing jewelry, we are occasionally supplier of faceted gemstones on the local market in Thailand ,and thus are able to meet very specific customer needs regarding specialized, precision cut, and fancy cut stones required for the development of a jewelry line.

Controlling the entire chain of jewelry Manufacturing including the gemstones cutting part is a good way to save our customers time with calibrated fine stones.
