Plum Diamonds is a premier ethical fine jeweler specializing in certified lab-grown diamonds and custom engagement rings. Committed to sustainability, transparency, and exquisite hand craftsmanship, Plum Diamonds offers 100% conflict-free lab diamonds set in recycled gold and platinum.
Showmine partnered with Plum Diamonds to redefine their e-commerce storefront on Shopify Plus—engineering an intuitive "Build Your Own Ring" customizer, real-time 4C diamond search filters, and high-trust luxury shopping journeys.

Bridging ethical sustainability with high-end bridal luxury, empowering couples to design their dream engagement ring online.
Purchasing a custom engagement ring online is a major financial decision. Plum Diamonds needed a platform that educated customers on lab-grown diamond quality while making ring customization effortless and foolproof.
Their previous setup lacked real-time diamond search filtering and dynamic 360-degree ring previews, resulting in prolonged decision cycles and missed conversions.
Showmine developed a custom ring configurator engine on Shopify Plus, allowing shoppers to select their setting, metal type, band style, and certified lab diamond cut with instant real-time price updates.
We coupled this with high-trust elements—including virtual try-ons, free home try-on kits, and seamless 1-on-1 virtual gemologist appointments.

Plum Diamonds educates customers on the ethical, environmental, and financial benefits of lab-grown diamonds compared to mined diamonds.
We integrated interactive educational modules breaking down carat, clarity, color, and cut certification directly within the shopping experience.

Our custom ring builder lets users pair certified lab diamonds with solitaire, halo, pave, or vintage ring settings in yellow gold, rose gold, white gold, or platinum, delivering instant pricing and high-definition visual previews.

Ultra-high resolution ring detail galleries and certificate inspection tools build supreme purchase confidence, lifting engagement ring sales and average order values.
