How I Helped a UK-Based Lab-Grown Diamond Brand Achieve 4X ROAS in 4 Months

From zero to profitable — Shopify, Google & Meta Ads all built from scratch.

The Challenge

A new lab-grown diamond brand in the UK approached me with an exciting but challenging task:

“We have a product and an idea. But we don’t have a website, no ad strategy, and we haven’t run any campaigns yet.”

The goal was clear:
🔹 Build the brand online
🔹 Start selling products
🔹 And do it all while staying profitable


🚀 My Full-Funnel Approach

🛒 Step 1: Shopify Store Setup

I started by building a Shopify eCommerce website from scratch:

  • Designed a premium-looking theme to match the luxury diamond market

  • Added product categories, filters, high-quality images, and secure payment setup

  • Set up essential pages: About, FAQ, Returns, Reviews, and Contact

✅ The website was optimized for mobile speed, trust signals, and easy checkout


📊 Step 2: Conversion Tracking & Analytics

Before running any ads, I made sure everything was ready for tracking:

  • Installed Meta Pixel and Google Ads Tag

  • Setup GA4, Meta Events, and Purchase Conversion Events

  • Created custom thank-you pages for better funnel tracking


📢 Step 3: Launched Paid Ads on Meta & Google

Once the store was live, I launched targeted ads on both platforms:

Meta Ads (Facebook + Instagram)

  • Used carousel and video ads to showcase the sparkle, quality, and ethical story of lab-grown diamonds

  • Targeted people in the UK searching for engagement rings, ethical diamonds, and wedding gifts

  • Retargeted website visitors and add-to-cart users

Google Search & Shopping Ads

  • Targeted high-intent keywords like “buy lab-grown diamond UK” and “ethical engagement rings”

  • Optimized product feeds for visibility in Google Shopping


📈 Results in Less Than 4 Months

  • Achieved 4X ROAS (Return on Ad Spend)

  • Reduced Cost Per Purchase by over 50% after initial tests

  • Traffic steadily grew, with high conversion rate from both cold and retargeted users

  • Brand started receiving organic sales and influencer interest due to growing presence


💡 Summary

In just under 4 months, I took this brand from zero presence to a fully running, profitable online store — with measurable results and steady growth.

“Great visuals, ethical storytelling, smart targeting, and solid backend setup — that’s how we made lab-grown diamonds shine in the UK market.”
