How do you grow a premium brand within the affiliate channel without relying on discounts? That was the challenge for The Diamond Store, a luxury retailer specialising in lab-grown diamonds and responsible British craftsmanship.
While The Diamond Store’s affiliate channel showed early potential, the programme was misaligned with its high-end positioning. By early 2025, the mix was dominated by voucher sites, driving 70% of volume - a conflict for a brand that rarely discounts.
With November’s peak trading period approaching, the brand needed to transition from discount-heavy volume to a sustainable, strategically aligned foundation that could deliver high growth at an efficient but flexible 8:1 ROI.
We implemented a "fearless" program reset, prioritising curated relationships and long-term brand equity over low-value clicks:
We took the bold step of removing 84% of active partners (107 out of 127) that were deemed low-value or misaligned with the brand. This allowed the team to focus on intentional, value-driven growth and rebuild the channel from the ground up.
We rebuilt the program to include 60+ high-quality partners by October 1st.
Moving away from siloed agency models, the affiliate strategy was integrated with Paid Social.
We leveraged CSS (Comparison Shopping Services) to drive 18% of total sales during peak. By maintaining optimal, stackable offers rather than aggressive cashback spikes, we reduced friction and protected margins.
This disciplined, brand-aligned approach delivered record-breaking performance during the critical Q4 period, proving that luxury and affiliates are a perfect match when managed with integrity:
Balanced Diversification with no single partner type exceeding 30% of total volume.
