Designed with a museum style interior, no detail has been overlooked in our Mosman store and engagement destination. Similar to Paddington, the store functions as an immersive showroom with the majority of pieces being made to order in our Sydney workshop and couriered to clients within 3 days. Our most popular pieces are available to take away immediately.


Book an appointment with our diamond specialist in our private engagement consultation room or visit us here on Sundays when you’ll find a jeweller welding our popular Soldered bracelets onto so inclined clients. Soldered appointments are released online at the start of every month and walk ins are welcome on the day.
