A record of turning diamond, gemstone and luxury expertise into commercial strategy, market development, brand value and measurable outcomes across the global value chain.

From mining and global sourcing to luxury retail, high jewellery, executive education and UHNW engagement, these selected examples demonstrate experience delivered in practice—not simply advised in theory.

Burgundy Diamond Mines — commercial strategy, market development and brand creation

Joined during Burgundy Diamond Mines’ early development phase, contributing to the commercialisation of a broader mine-to-market strategy spanning natural diamonds, global sourcing, product development, luxury branding and international market engagement.

Opportunity

Burgundy Diamond Mines was an early-stage listed diamond company seeking to create value beyond exploration by developing a differentiated, vertically integrated natural-diamond proposition.

Leadership & Execution

Led commercial strategy across global sourcing, valuation, cutting and polishing, proprietary certification, product development, luxury brand creation, international distribution and UHNW engagement.

Key Outcomes

Developed and executed initiatives spanning Maison Mazerea, exceptional natural diamonds, international sourcing, luxury collaborations, global launches and private-client engagement—helping translate a mining-sector proposition into a broader consumer-facing diamond business.

Commercial Significance

Demonstrated how expertise across the complete diamond value chain could be converted into brand equity, market access, commercial relationships and enterprise value within an unusually compressed timeframe.

A$200m+ market capitalisation reached during the period of this broader commercial development.

Maison Mazerea — branded natural diamonds, proprietary certification and luxury positioning

Developed Maison Mazerea as a luxury natural-diamond proposition designed to move exceptional stones beyond commodity value through provenance, proprietary grading, design, storytelling and international market positioning.

The Grace Diamond — exceptional natural diamond, royal association and international luxury engagement

Selected from the final Argyle Pink Diamonds Tender, the 1.79-carat Argyle Stella™ was one of just five named “hero” diamonds chosen from the historic last collection of rare pink and red diamonds produced by Rio Tinto’s Argyle mine. A square radiant-cut Fancy Vivid Purplish Pink diamond, it already carried exceptional provenance, rarity and historical significance. The opportunity was to take that extraordinary natural asset further — developing it into The Grace Diamond and creating a broader story connecting Australian origin, high jewellery, philanthropy, royalty and UHNW engagement.

Opportunity

Taking one of the most historically significant diamonds from Argyle’s final Tender and create a luxury proposition worthy of its rarity — one capable of extending beyond the stone itself into high jewellery, international storytelling, philanthropy and private-client engagement.

Leadership & Execution

Led the commercial and strategic development of the diamond from its Argyle provenance through naming and positioning as The Grace Diamond, its incorporation into a bespoke high-jewellery necklace by Lorenz Bäumer, and its presentation through international luxury and philanthropic channels.

Key Outcomes

The Grace Diamond became the centrepiece of a wider programme spanning high jewellery, international events and UHNW engagement. The necklace was worn by H.S.H. Princess Charlene of Monaco at a Princess Grace Foundation event in New York, extending the diamond’s story into a globally recognised luxury and philanthropic context.

Commercial Significance

Demonstrated how the provenance and rarity of an exceptional natural diamond can be amplified through disciplined storytelling, design and strategic partnerships — converting an already extraordinary gemstone into a broader luxury platform with international visibility and emotional resonance.

From Argyle’s final Tender to Monaco and New York — one historic natural diamond transformed into a global luxury narrative.

Maison Mazerea, The Grace Diamond and Franck Muller

Building on the Maison Mazerea concept of Haute Diamantaire — elevating exceptional natural diamonds through provenance, design, craftsmanship and narrative — the collaboration with Franck Muller extended that philosophy into the world of haute horlogerie. The Grace Diamond became the focal point of an extraordinary tourbillon concept, bringing together rare gemmology, specialist watchmaking and high luxury storytelling.

Opportunity

Create a cross-category luxury collaboration capable of placing The Grace Diamond within one of the most technically sophisticated and exclusive expressions of watchmaking, while extending the diamond’s relevance to a new UHNW audience.

Leadership & Execution

Led the commercial and strategic engagement surrounding the collaboration with Franck Muller, coordinating the integration of The Grace Diamond into a bespoke tourbillon concept and its presentation at Franck Muller’s Watchland headquarters in Geneva during the 2023 GemGenève period.

Key Outcomes

The collaboration demonstrated the versatility of an exceptional natural diamond as a luxury asset beyond traditional jewellery, creating a compelling intersection between haute diamantaire and haute horlogerie and generating further international engagement around The Grace Diamond story.

Commercial Significance

Demonstrated how the Haute Diamantaire proposition could move beyond traditional high jewellery into adjacent luxury disciplines, creating a platform for cross-category collaboration, UHNW engagement and additional value around exceptional natural diamonds.

Haute Diamantaire met Haute Horlogerie — extending The Grace Diamond from exceptional gemstone to cross-category luxury asset.

Paris, Perth, New York and Monaco — connecting exceptional diamonds with private clients, patrons and international luxury audiences

Developed and executed a programme of international launches, private events and relationship-led engagement designed to take exceptional natural diamonds beyond product presentation and into the world of luxury experience, philanthropy and UHNW connection.

Opportunity

Create direct access to the right audiences for exceptional natural diamonds and high jewellery — not simply through traditional retail, but through carefully curated environments where provenance, rarity and story could be experienced personally.

Leadership & Execution

Led the planning and commercial execution of launches and private engagements across Paris, Perth, New York and Monaco, working across luxury presentation, client development, strategic partnerships and invitation-led UHNW engagement.

Key Outcomes

Built relationships with private clients, patrons and influential luxury audiences, strengthened international visibility for the proposition, and converted product, storytelling and access into meaningful commercial engagement and sales opportunities.

Commercial Significance

Demonstrated that exceptional diamonds require more than exceptional product — they require the right narrative, the right environment and access to the right client communities.

Exceptional product. Exceptional access. Exceptional clients.

Building high-performing teams, luxury client experiences and executive capability

Across luxury retail, jewellery leadership and executive education, Drew has combined deep product knowledge with commercial discipline, coaching and client engagement — developing high-performing teams, strengthening sales capability and translating complex diamond and gemstone expertise into compelling, practical learning.

Opportunity

Build sales and leadership capability in environments where product knowledge alone is not enough — where success depends on confidence, storytelling, clienteling, commercial judgement and the ability to communicate value at the highest level.

Leadership & Execution

Led luxury retail teams, developed national training programmes, coached emerging leaders and delivered diamond and jewellery masterclasses for sales professionals, private clients and senior executives. Programmes were designed around practical application — connecting gemmological knowledge, selling excellence, customer experience and profitable growth.

Key Outcomes

At Tiffany & Co., contributed to flagship revenue growth from US$32 million to US$64 million and top-five global store performance through clienteling, coaching and disciplined execution. At Gregory Jewellers, established national training curricula and digital learning infrastructure to strengthen capability and leadership succession. Executive education later extended to senior industry audiences, including a mine-to-consumer strategy presentation to Rio Tinto CEO Jakob Stausholm and approximately 50 senior executives in Washington, DC

Commercial Significance

Demonstrated that expert knowledge creates greater value when it can be transferred — improving confidence, client experience, conversion, leadership capability and commercial performance across organisations.
