Australian Diamond Valley began as a love for Australian Argyle diamonds. Each diamond captures the beauty of our unique Australian landscape. We handcraft jewellery pieces with love and respect to the rarity of Australian Argyle diamonds and their special origin. 

We are one of Australia's leading manufacturing jewellers with over 40 years experience in the Australian jewellery industry. We began crafting custom quality handmade pieces using the rarest of diamonds for the luxury label jewellery stores you know and love.

Our experience with rare diamonds over three generations means you can be assured that your jewellery piece is authentic, Australian, ethical and sustainable.

We love to custom make pieces from our Sydney workshop. Looking to have your dream design come true? Get in touch with us to create your one-of-a-kind design at or reach out to us through our contact form below.
