Marina Antoniou Jewellery


Every piece of Jewellery is handmade to order by Marina in her studio in Sydney’s Inner West. Each piece is crafted using precious metals and gemstones and is made to last a lifetime.

All materials used to make your special pieces are locally sourced from Australian-owned and operated businesses. Gold is purchased here in Sydney, and gemstones are supplied by independent and family-run gemstone merchants from around the country.


Almost all the time, Marina sources stones directly from individual or small, family-run mines and miners, cutters, merchants and fossickers from some of Australia’s historic mining towns.

Sapphires are sourced from where they are found in QLD and NSW, towns such as Rubyvale, Inverell, Lava Plains and Sapphire. Opals come from Andamooka, Winton, Quilpie and Lightning Ridge, chrysoprase from Malborough and small diamonds— white, pink and cognac— from Argyle in Western Australia. Then there is the Australian turquoise, extremely rare, originating from the only commercial Turquoise mine in Australia, which ceased operating in the 1970s. It is untreated, solid, natural, and unlike anything else on the market.
