1.30ct Cognac & White Diamond Trilogy Ring


This unique engagement ring has all the timeless beauty of a classic trilogy ring, with a beautiful 1.01ct cognac diamond as the central stone. Two sparkling white round brilliant cut diamonds complete the trilogy.

The highly polished 18ct yellow gold band is of an elegant half round profile, subtly tapering at the shoulders.

Each diamond is meticulously bezel set in platinum. Our jewellers love platinum due this precious metal's white tone, strength and durability.

Designed and made with responsibly sourced materials in the Sargisons workshop in Hobart, Tasmania.
