Our Work – Our Commitment

We specialize in the creation of custom designs and bespoke remodelling projects. Our unique creations are proudly designed and handcrafted in our studio at 366 Adelaide Street East in Toronto, Canada.


We always collaborate with each customer in person, sharing our artistic vision, craftsmanship experience and gemological knowledge to create custom-made, exceptional and personal pieces of jewellery.


We custom make each ring or band to our customer’s requests or finger size, and artistically shape the ring for a perfect, yet comfortable, look and feel. We go to the extent of preparing custom, solid prototypes so that we can ensure all details are perfect in advance of creating the final ring. We never stop until our customers are fully satisfied.

Custom Designed
