Welcome to American Gemstone Group’s custom jewelry factory. We offer complete solutions for jewelry businesses and jewelry designers looking for a faster, more cost effective way to manufacture their fine jewelry productions.

We are an American company with our own fully owned jewelry factory in Bangkok, Thailand. We do all of our work in house, from casting through plating, allowing for our strict QC procedures at every stage of the manufacturing process. We’ve incorporated technology into every aspect of our production to allow for some of the fastest turnaround times in the industry.

Jewelry Factory Floor


To enable rapid delivery, our jewelry factory uses internal tracking systems to bar-code and scan every piece of jewelry as it moves through our factory. This allows our  proprietary intelligent tracking systems to inform our production team if any pieces are taking an unusual amount of time in a certain process. In this way we’re able to sync our internal production calendar with the information provided to our clients on the client-side portal. It’s through this same system that we are able to log and notate production methods and notes specific to every piece that we produce, which helps us ensure that we employ best practices for a particular SKU every single time that we make it.

Advanced Equipment


Jewelers at our factory use hydrogen jewelry torches instead of acetylene as it burns cleaner and makes a smaller flame. This allows for more precise welding and stronger welding joints. In addition to hand welding, we employ spark welders and laser welders for chains. A common problem among inexperienced jewelry factories is that they use hand torches to weld chains to clasps and other components. This heats up the solder in the links and causes the chain links themselves to become extremely weak causing defects later on with your customers.

In-House Casting


Our R&D department is constantly seeking new ways to innovate the production process through the adoption of industrial practices into jewelry manufacturing. It’s through this open minded approach to technology that our jewelry factory has been able to grow extremely rapidly and over the past 10 years become an industry leader in branded jewelry manufacturing.

Cutting Edge Technology


Our production molds employ RFID codes that talk to our wax injectors to ensure that injection settings are the same every time. This leads to a very high degree of product consistency right from the beginning of the production cycle and less defects that need manual correction later. We also use special molds that are low shrinkage, do not require vulcanizing, and have production durability similar to that of normal vulcanized rubber. This gives us much better surfaces and sharper detail then typical of vulcanized rubber molds.

Highly Skilled Jewelers


While we try to employ technology to improve quality wherever possible, manufacturing jewelry will always rely heavily on skill. To this end we employ some of the most skilled jewelers in the world. Our micro-pave setting is done by hand, using microscopes, and to the highest level of Swiss standards. Our jewelers come from a variety of backgrounds but many have worked for top 10 brands at various points in their careers. Thailand, being a jewelry manufacturing hub, has some of the most skilled artisans in the world. Our Thai jewelry factory has stringent recruitment practices and we constantly seek out the best of the best.

Top Quality Control


Our quality control team is some of the best in the industry. Their job is to ensure that QC never needs to be carried out again by you after delivery. In this way, you can confidently deliver your products, focus on your job, and let us do the rest.

Your Own Private Catalog


Our web portal will help you confidentially submit your jewelry designs to us for quotation and development. Through our web interface, all of the products that you have developed with us are contained in your encrypted user account in a private catalog view-able only by you, and order-able with the click of a button. All of your designs, masters, molds, and production devices will remain your property and be used exclusively for making your products for you.
