Case Study: a lab-grown diamond and fine jewelry e-commerce brand achieves its first $1M sales month with AdVenture Media’s Meridian-based MMM

Lab-grown diamond and fine jewelry e-commerce hits first $1M sales month with AdVenture Media

The customer, a lab-grown diamond and fine jewelry e-commerce brand, was facing challenges with its digital advertising performance. Its blended return on ad spend (ROAS) was below its break-even point, and conflicting platform-reported data made it impossible to trust which channels were truly driving incremental revenue. To address this, AdVenture Media implemented a Meridian-based Marketing Mix Model to uncover the true performance of each advertising channel.

AdVenture Media's analysis revealed that Meta prospecting was the most effective channel, while several Google programs were underperforming. Acting on these insights, AdVenture reallocated the budget, decommissioned poor-performing campaigns, and refreshed creative assets. As a result, the client achieved its first-ever $1 million sales month, with Meta prospecting ROAS climbing to 7.25x and $5,000 in monthly underperforming spend being eliminated.
