MiaDonna is a U.S.-based fine jewelry brand headquartered in Portland that specializes in lab-grown diamond jewelry and engagement rings. Founded in 2005, the company was one of the earliest pioneers in bringing lab-grown diamonds to mainstream consumers, positioning itself as a more ethical, sustainable alternative to traditional mined diamonds. A certified B Corporation, MiaDonna emphasizes responsible sourcing, recycled precious metals, and lab-grown diamonds that are chemically and physically identical to mined ones. The brand built its reputation around brilliance without compromise: high-quality lab-grown diamonds, ethical production, and a luxury jewelry experience for modern, socially conscious customers.
“Mage Loyalty is hands-down the best loyalty platform on Shopify, and the team behind it is just as exceptional as the product. When we needed customizations specific to our business, the Mage team worked directly with us to make it happen. And the wishlist feature deserves its own callout: it's the best we've come across, period. Beautifully integrated, intuitive for customers, and a real driver for our store.”
MiaDonna didn't want a loyalty program that was just a discount engine. As a luxury, B Corp fine jewelry brand, they needed an experience that felt high-end and on-brand at every touchpoint. They also needed to go beyond basic points: a cashback-style system they could fully control, with custom earning rules, advanced redemption methods, checkout components, and a wishlist that unified with customer accounts, all without compromising the premium feel of the brand.
MiaDonna built loyalty, cashback, wishlist, and customer accounts with Mage, tailored to their exact aesthetic with advanced customization and premium components out of the box. Customers earn store credit worth $1 for every $20 they spend, redeemable like cash at checkout. A wishlist unified with customer accounts lets shoppers save high-end pieces and pick up where they left off, while the account dashboard surfaces upsells that drove $15,000 in revenue in the first month alone.
Custom earning rules MiaDonna fully controls: customers earn $1 in store credit for every $20 spent, around 5% back, spent like cash at checkout.
Premium checkout components let customers redeem rewards instantly and apply their store credit balance against the order.
A premium wishlist that lives inside customer accounts, so shoppers can save and return to high-end pieces seamlessly.
A fully branded account experience with upsells that generated $15,000 in revenue in the first month.
Advanced theming and a level of design detail that match MiaDonna's luxury brand at every touchpoint.
MiaDonna's wishlist is unified with customer accounts, so shoppers can save the pieces they love and return to them anytime. In the first two weeks of launch alone, customers wishlisted over 1,500 items, and those saves converted: $12,662 in revenue across 8 orders on high-end jewelry. For a considered, high-value purchase like fine jewelry, a beautiful wishlist isn't a nice-to-have, it's a direct revenue driver.
