Fine jewelry, made to a standard you can verify.
AURELIA designs and casts 18k gold and certified diamond jewelry — one bespoke piece for a private client, or a full production run for a retail partner. Every stone traceable, every setting inspected.
Individually Cast, Meticulously Set
Every ring and pendant is created in-house using vacuum induction casting and hand-finished by master jewelers in our state-of-the-art atelier.
Traceable Diamonds & RJC-Gold
We source only Kimberley Process certified stones and audited conflict-free precious metals, so you can trace your jewelry from mine to market.
One Piece or Ten Thousand
The same casting floor and quality checks serve a single custom order and a full wholesale production run — no compromise either way.
CAD to Casting
Send a sketch or a reference photo. Our team builds a precision 3D model and a resin prototype before anything touches metal.
