Quality System That Works


As quality jewelry begins at material procurement, our high-quality benchmarks start with our supplier base. All material purveyors perform routine auditing to ensure they deliver top-grade and responsibly-sourced materials.
Our quality management process is to continuously equip our team with the latest requirements in jewelry production. We also update our protocols to reflect new practices.
Our production process follows a standardized operation workflow developed based on ISO9001, indicating each step and how to maintain our established benchmarks.
Maintaining a traceable paper trail helps us locate potential issues within the process and make appropriate corrections. All documents are appropriately kept and ready to be used as references when needed.

Incoming Material Inspection
1. Metal Purity Inspection
All metal materials must pass a strict purity
inspection to ensure they contain no additives or
harmful chemicals. This guarantees the metals are
safe and can handle the shaping process.
2. Pearl Inspection
Several tests are done on the pearls that come into
the production facility, including their shape, luster,
weight, and size. Maintaining consistency is key to
optimal pearl jewelry creation.
3. Chains & Clasp Inspection
Links within the chains are checked by our
inspectors, making sure they are correctly attached
and won’t fall off while in use. The locking
mechanism and springs within the clasps are also
inspected closely.
4. Gemstone Inspection
Aside from checking if the gemstones are
sustainably sourced, these precious stones undergo
a series of examinations to guarantee their
authenticity and durability.
