How it's made

Shaped by the stone

01
The stone comes first.
Every stone and pearl has its own shape, texture, movement, and natural character. That is where the design begins.
02
The chain follows.
The chain is shaped around the material, whether it cages, links, wraps, or frames it. Nothing is hidden. The construction is part of the beauty.
03
Made to move with you.
Engineered, shaped, and finished by Michael in New York, start to finish. No two pieces come out the same.
