    Discover our extensive trilogy ring collection

    Trilogy rings, also known as three-stone rings, are beautiful, classic symbols of love. The trio of stones set into the band symbolises the past, present and future of a relationship. For some, these rings symbolise the three pillars of a healthy relationship: friendship, love and fidelity. In certain religions, it is also reminiscent of The Holy Trinity.

    Our collection has something to suit every style, from traditional, understated designs to more contemporary, stand-out interpretations. No matter what you're after, we've got something for everyone that just feels right. Through customisation options, you have the opportunity to make the ring your own to represent your own unique love story. Browse our collection and discover the trinity ring which speaks to you.

    Choose some diamonds for your trilogy ring

    Choosing the diamonds for your trilogy engagement ring is all about what feels right for you. Whether you like the three matching stones look or prefer to mix things up with varying sizes and stones, there’s no right or wrong way to go. You can stay classic with white diamonds, go bold and beautiful with black diamonds or even choose eco-friendly lab-grown diamonds. When it comes to clarity and size, think about what suits your personal style and budget. If you’re unsure where to start, the filter on the side will take you to your favourites, or you can use our ‘design your ring’ feature to create something completely personal. After all, it’s your ring, your love story—let it shine the way you want.


    Choose your diamond shape

    Shape Popularity Shape Popularity

    The shape of your diamonds makes all the difference in how your trilogy engagement ring looks and feels. Round diamonds are a classic favourite, loved by half of Abelini’s customers for their timeless sparkle. Emerald cuts come in as a close second, offering a sophisticated, elegant vibe with their sleek, step-cut facets. If you’re into something bold and modern, the sharp lines of a princess cut could be perfect for you. Explore your options using our filters or the ‘Design Your Ring’ feature to find the shape that suits your style best.

    Choose your trilogy ring metal

    Style Popularity Style Popularity

    The metal of your trilogy ring defines its style and longevity. Sleek and modern, white gold, our most popular metal, is preferred by nearly half of our customers and enhances the brilliance of diamonds. Neutral in tone, it works with almost any other diamonds and gemstones, and you can wear it all the time. Yellow gold, the second most popular choice, adds timeless warmth and pairs beautifully with vintage or classic designs. Platinum’s unmatched durability and natural lustre make it ideal for showcasing a trilogy’s elegance, while rose gold lends a romantic glow that softens the overall appeal. Use our filters or the ‘Design Your Ring’ feature to explore metals that perfectly complement your ring.

    Our commitment to ethical diamond sourcing and certified standards

    At Abelini, ethical sourcing and responsible craftsmanship are at the heart of everything we do. That’s why every diamond in our engagement rings is conflict-free, sourced from suppliers who follow the World Diamond Council System of Warranties and abide by the Best Practice Principles of the DTC. That means no stones ever have links to violence, human rights violations or rebel-controlled areas. By choosing one of our rings, you’re not just celebrating your love—you’re making a decision that speaks to your values.
