The Charles Koll Difference

To ensure the quality and integrity of each creation, every process of jewelry creation from client-guided design to casting, prototyping and diamond setting is carried out and quality-checked – step by step – in our studio.


From appraisals and repairs to fully custom design and refurbishing, we offer personalized service.


We do everything in-house in our glass-walled workshop, so you can see your designs brought to life, step by step. Plus, doing it ourselves means much shorter wait times than big box jewelers.

Artists at Heart

Custom jewelry is not just part of what we do; it is foundational for Charles Koll. Through collaboration we deliver jewelry that resonates, excites and inspires.
