Manufacturing Process A-Z

Design
Every piece begins with thoughtful design and inspiration. Our in-house team work to bring each concept to life—balancing form, function, and fine detail. Whether it's a custom charm or a new chain style, we ensure every design is both beautiful and durable for everyday wear.
Mold, Wax, & Investment
There are several ways of creating a mold but the most common are rubber and metal molds. The mold will ensure the intricacies of the design are kept throughout the casting process.
Once we have the mold we will shoot wax into the mold and attach to a tree which will placed into an investment. Once the investment material has settled, the flask will be then placed into a burning kiln which helps burn away the wax leaving behind a cavity that works as the final mold for the jewelry piece. The wax melts out through a couple of sprues that are attached to the bottom of the mold before placing it in the kiln. The number of sprues depend on the size of the piece of jewelry. This is also called the burn out cycle in which wax models are connected to each other using a sprue forming a tree-like formation. This formation is then put into a metal flask which is filled with a slurry of plaster. The flask is then debubblized to get rid of any air bubbles or air pockets in the mold. Once the wax has melted away and the mold has been invested leaving behind no remaining wax residue and only a hollow impression to serve as a mold for jewelry, it is time to pour in the metal material.


Casting
The metal is melted at a high temperature and poured into a flask for it to funnel through intricate cavities before it cools. Once the metal has been poured, it is allowed to cool down for a few minutes before being dunked into cold water to retain its final shape. The amount of time required for the cooling process depends on the type of metal that is being used and its melting point.
Next, the jewelry is polished by using a buffing wheel to give the piece a shiny, complete finish. Buffing machines, enamel clothes, polishes and filers can be used to the give the final piece the desired shape and style.
If required, the pieces will be plated and finishing touches made. Our plating is nickel free making them hypoallergenic and safe for sensitive skin. This process is done in-house and overseen by skilled technicians to maintain consistency and meet our high standards.
Inspection & Shipping
All our jewelry go through a detailed quality inspection by our team to ensure it meets our standards for craftsmanship, finish, and durability. We check for any imperfections, clean each item, and carefully package it to protect against damage during transit. Once approved, your order is promptly shipped with care.
