Boutique Bespoke Jeweller · Sydney
Designed with meaning. Made just for you.
In a quiet studio above King Street, Adriana and her artisans handcraft engagement rings, fine jewellery and pearls — each piece made to order, made to be kept, and made to mean something.

The Bespoke Journey
Three simple steps to your piece
Sit down with us — in the studio or online. Bring inspiration, heirlooms, or nothing at all. We'll listen first.
Your piece takes shape through sketches and CAD, refined together until it feels unmistakably yours.
Handcrafted in our private Sydney workshop over 6–8 weeks, then placed gently into your hands.
Design Your Own Ring
Or begin today, from home
Our ring builder lets you start wherever feels natural — we'll take it from there.
The Collections
Curated, with consideration

The Birth of THELIS
Made by hand. Led by heart.
THELIS was founded in 2024 by Adriana Theodore with a clear vision: a place where people can personalise their jewellery or explore curated collections designed for everyday elegance and life's most special occasions.
Every piece blends timeless sophistication with modern craft — responsibly sourced, handcrafted in our private studio, and finished with the kind of care only a small atelier can give.
