The three stones in a three stone engagement ring are traditionally understood to represent the past, present, and future – a design that tells the story of a relationship across time.
Some couples also interpret the stones as representing friendship, love, and fidelity, or other personal meanings that resonate with their journey. It's one of the few engagement ring styles where the design itself carries a narrative, making it a particularly thoughtful choice.
A lab-grown diamond three stone engagement ring features a center stone flanked by two matching or complementary lab-grown diamonds — one on each side. The three stones traditionally symbolize the past, present, and future of a relationship, making this one of the most meaningful engagement ring styles available.
At MiaDonna, each stone is an ethically grown diamond that shares the same brilliance, hardness, and beauty as a mined diamond.
Three stone engagement rings are incredibly versatile when it comes to diamond shape combinations. The most popular pairing is a round brilliant center stone flanked by two matching rounds — clean, classic, and endlessly brilliant. Oval and pear shapes are also widely loved, particularly when the side stones are tapered to follow the elongated profile of the center stone.
For a more distinctive look, a cushion or emerald cut center with trillion-shaped side stones creates a striking geometric contrast. The beauty of a three stone ring is that the shape combinations can be as personal as the relationship it celebrates.
Yes — and mixing shapes is one of the most creative aspects of designing a three stone ring. A popular approach is pairing a round or oval center stone with tapered baguette or trillion-shaped side stones for a look that's both classic and distinctive. At MiaDonna, our design team can help you explore combinations that complement your center stone and reflect your personal style. Custom shape mixing is available across our lab-grown diamond three stone engagement ring collection.
MiaDonna has specialized in lab-grown diamond jewelry since 2005, and our three stone engagement rings reflect that depth of experience. Each lab-grown diamond three stone engagement ring is crafted with ethically grown diamonds set in refined recycled metals — built to the same standard regardless of budget. Our team can guide you through stone selection, shape combinations, and custom design options to create a ring that's meaningful, personal, and made to last.
Yes — particularly because you're selecting three diamonds rather than one. Lab-grown diamonds offer the same quality as mined diamonds at a more accessible price point, which means you can pursue larger or higher-quality stones across all three positions without the premium associated with mined diamonds. The result is a ring with significantly more presence and brilliance for your budget. It's one of the styles where the value of lab-grown diamonds is most visibly felt.
