The House

A private jewellery practice shaped by curiosity, intuition and considered design.

de courcier is a fine jewellery house centred on rare coloured natural diamonds and exceptional gemstones, founded by Tarli.

Each piece is designed around the natural character of the stone — its tone, proportion, and presence. 

We create jewellery through a process of observation, conversation and thoughtful composition. Each piece is approached individually, without the constraint of a fixed style or predetermined collection.

As Private Jeweller and Designer, Tarli works closely with each client from the earliest idea through to the final piece.

Her role moves between designer, gemstone curator and trusted adviser, understanding what a piece needs to express, sourcing the right materials and refining each decision until the design.

Each commission is then meticulously handcrafted in Australia by exceptional local master jewellers, bringing together traditional craftsmanship and contemporary precision to create heirloom pieces made to be worn for generations.
