Every piece in this collection is solid 9ct yellow gold, the same metal from the surface right through to the core. We never plate. Our gold is refined in Australia by Palloys, part of Pallion, whose 100% Australian gold claim is independently audited by the Responsible Jewellery Council, so we can tell you where it came from. It is alloyed with copper, silver and zinc, with no nickel in it. Everything here is made to order by hand in our Stanmore studio, and every piece carries lifetime repairs.
