Our People

With over 100 years combined industry experience, you're in the best hands.

We’re like most independents, family owned and operated, we are passionate about what we do, and what you do too. We’re invested, we’ve been listening and we’re here for you.

 Our Story 

 New Group. Experienced Hands. 

Our team has been supporting independent jewellers since 2005, and many of those jewellers chose to build what comes next with us. That means two decades of trust, strong relationships with the suppliers you rely on, and a real understanding of how independent business works.  

What's new is the energy: fresh technology of our own, a team with the capacity to look after every member, and a clear focus on the next generation of jewellers and the customers they serve.

Josh Zarb

Chief Executive Officer | Retail Keynote Speaker

Josh is the driving force behind Independent Jewellers Collective, the energy, vision and strategic mind behind a business built to champion Australian independent jewellers. With a rare combination of commercial intelligence and genuine people skills, he has spent 28 years helping independent retailers grow stronger, more profitable and more future-focused.

His retail career began at Michael Hill Jeweller, where he progressed from store manager to regional manager. He then moved into senior leadership, including group general management within the jewellery industry, with experience across luxury retail, fashion retail and large-scale event management. He's built a reputation for turning under-performing businesses into profitable, sustainable operations, and he's served as a director and vice president of the Jewellers Association of Australia (JAA). His honours degree in statistics underpins his analytical approach.

A sought-after motivational keynote speaker, Josh knows how to inspire teams, challenge leaders and unlock potential. He spends much of his time on the road visiting stores across Australia, and as the key link between members, suppliers and the wider industry, he's always searching for new ideas and innovations to bring home to the collective.

Outside of work, you'll find Josh on the water, fishing or kayaking, or at home smoking meat on the BBQ. He also enjoys lifting weights at the gym and taking his two children bike riding.

Senthil Jayaraman

Chief Technology Officer

Senthil is the mind behind our technology. He wrote, designed and built both Facet Flow, our cloud-based point of sale, and One Billing, our exclusive central billing platform. With more than two decades of senior IT experience, his financial business systems and business intelligence tools are in wide use right across Australia. He has worked everywhere from startups to big financial corporations, including Westpac, where he helped develop their online banking software. In previous roles, he also built a complete central billing suite integrated with CRM and ERP systems.

Senthil has a hawk eye for detail and a real passion for automating the mundane routines in software, so your time goes to your customers instead of your admin. At Independent Jewellers Collective, he keeps One Billing and our communication platforms running smoothly.

Away from the screen, Senthil is a keen gardener, an avid cyclist and a yoga enthusiast. His weekends are often spent catching up with his family and two boys. 

Summer Gartrell

Head of Marketing

Summer helps independent fine jewellers across Australia and New Zealand build stronger, more profitable, future-focused businesses. She began her career in Creative and Promotions at the KISS / Australian Radio Network, then moved into marketing at Universal Music Australia, supporting independent music stores. For more than 20 years since, she has brought that creative eye and commercial discipline to independent jewellers.

As Head of Marketing for Independent Jewellers Collective, Summer leads brand positioning and high-impact campaigns, including helping retailers become the "Custom Design Destination" in their town. She develops our exclusive white label and Bespoke Custom Design collections, equips stores with the tools to close more sales, from try-on ranges to websites and live pricing, and hosts our Retail Experience events on everything from staff training to succession planning. A passionate champion of the independent sector, she's known for clarity of vision, high standards and a relentless focus on results.

Away from work, Summer loves interiors, and gardening. She's fascinated by all things health and longevity, fits in the gym and pilates when she can, and spends the most of her spare time chasing after her two young kids.

Emily Lucas

Digital Marketing Executive

Emily is a digital marketing and content specialist with 13 years of experience supporting small and medium business owners across jewellery, giftware, homewares, books, media, entertainment and even high-end pet care. She knows the retail counter from the inside, having spent many years selling luxury accessories with Luxottica Group before building a career managing digital campaigns from creation through to execution, across a range of mediums. 

Emily understands how little time retailers have, and how hard it is to keep up with an ever-changing digital landscape. A passionate, lifelong student of her field, she loves to teach, share what she knows and turn complex subjects into clear, actionable goals that business owners can act on.

Away from work, Emily is a creative at heart. She loves to read, write and draw, and as a former ballerina...she still loves to dance, when she isn't chasing after her young child.

Andrew Ralph

Member Services & Special Projects

For Andrew, jewellery has never been just a career. It's a lifelong calling. He started at 10 years old in the family store and has spent more than four decades mastering every facet of the industry. A qualified gemmologist and registered valuer with an Associate Diploma in Business, he combines technical precision with a clear vision for growth.

Andrew has seen the whole picture. He's scaled a business to six stores and a team of over 100, managing everything from back-of-house systems and HR to brand and store development, always keeping the customer experience first. Today he runs a bespoke, appointment-only jewellery business with a team of two, which gives him the time to focus on process and the customer experience. He's still a jewellery retailer himself, so he knows exactly what our members are dealing with, and he uses that experience to train, motivate and empower them to take their businesses where they want to go.

Helping people is Andrew's real passion, whether that's a fellow jeweller or the community. Outside of work, he loves to travel and can usually be found barracking for his AFL team on the weekend.
