About Us

About US

 Connecting your story to Mother Earth’s finest creations.

With more than 40 years’ experience in the diamond and gemstone industry, Avi Cohen founded Diamonds and Jewellery Centres of Australia (DJCA) in 2012.

Opening the doors to DJCA was Avi’s love note to the beauty and mystery of nature’s precious gemstones and their power to convey meaning.

At DJCA, our passion is working one-on-one with you to share this wonder and tell your story through ethically sourced stones and beautiful, bespoke jewellery design.

Trusted again and again by our clients, we’re proud of the community we’ve built and hope you’ll invite us to help tell your story.

Love Avi. Can't wait to go again. It's a must have destination for the jewellery lover. It was a lovely journey of design and I was very happy at the end. Avi offers constructive and genuine advice - your piece is just one part of the experience that leaves a smile in your heart.

Our founder

Avi Cohen

Avi’s knowledge of the diamond and gemstone industry is invaluable.

A creative at heart and a natural storyteller, Avi never misses an opportunity to find and showcase detail for each client. He is guided by the philosophy that “Every piece of jewellery we create has a meaning; every design will be a masterpiece.”

Starting his career as a gem setter and watch repairer on Israel’s Mediterranean coast, Avi spent more than two decades travelling the world as a respected diamond and gemstone merchant.

During this time, Avi perfected his craft and met some of the most influential people in the industry.

In 1985, Avi and his young family moved to Brisbane. It’s here that DJCA was born.

In 2018, the family sailed west to Perth after falling in love with Western Australia’s unique coastal lifestyle.

In the same year – just a stone’s throw from the Indian Ocean and in a beautiful semi-heritage listed studio – Avi welcomed his first customers to DJCA North Beach.

Today he leads the DJCA team as CEO and Creative Director. He is always ready to share his knowledge and expertise, and stories from around the world.

the DJCA difference

We’re not your typical jewellery studio.

We’re storytellers – turning life’s moments and memories into bespoke jewellery, as unique as you.

It’s an honour to hear the stories that are shared across our desk. Tales of love, achievement, heartache, and new life chapters – no two are ever the same. And neither are the pieces we create.

It’s why getting to know you is at the heart of what we do. And the reason why we love it.

And it’s how we’ve become one of Perth’s most trusted bespoke jewellers.

We can’t wait to hear your story.

I had a wedding band and engagement ring made with Avi and love the result. It was such a fun process and I would not hesitate to go back there and would highly recommend anyone who seeks bespoke jewels to visit. The quality of my rings represents great value for money 😊

Our studio

Our studio is the epitome of cutting-edge craftsmanship, where creativity knows no bounds. As the heart of innovation, we thrive on collaborative design processes that weave personal stories into stunning masterpieces.

Come in and talk to us about your dream piece or browse our collection of ready to wear fine jewellery from 10-4pm, Monday to Friday.

Our Neighbourhood

We believe that buying jewellery should be a memorable experience. So why not make a day of it?
Keep this in mind the next time you plan a visit to see us.

our community

As creatives at heart, we love to support our local artists, and regularly turn our studio into a community gallery space and host popular twilight art events throughout the year.

Our Values

Our work is always underpinned by:


We believe in traditional customer service and the power of conversation – we won’t use paperwork to get to know you and you’ll never feel alone in the design process. You’re in safe hands at DJCA.


We consciously create pieces with your story in mind. From design to material selection, each custom piece is as rare as you.


We create jewellery that lasts generations, combining traditional methods with the latest technology. For your added peace of mind, a lifetime craftsmanship warranty and continuous aftercare service comes standard.


We’ve been working in the diamond and gemstone industry for more than 45 years. We’re experts in fine jewellery and natural gemstones and commit ourselves to exceeding industry standards of excellence.


Before calling Australia home in 1985, we travelled the world as gemstone experts. We built strong business relationships and friendships with suppliers who now help us source the finest stones from around the world.


Our beautiful North Beach studio is also a local creative collective. A place to talk about and design jewellery; a place for new and old customers to pop in and share stories and ideas; and a gallery space for local artists to share their works.
