The way three diamonds sit together can make a big difference to the finished ring. While the centre diamond is often larger, you can choose different shapes and sizes to create the look you prefer.
Round, oval, pear, cushion, and emerald-cut diamonds are all popular choices for trilogy rings. You might prefer three matching shapes for a classic look or combine an oval centre diamond with pear-shaped side stones for something different. Explore our custom oval engagement rings and custom pear engagement rings for more inspiration.
