Trilogy & Three Stone Engagement Rings

Three stone engagement rings, also called trilogy rings, set a larger centre stone between two smaller side stones. If you are looking at three stone styles, you probably want more presence than a solitaire and like the symmetry of a centre stone framed by two others.

• Meaning built in: The three stones are often read as past, present and future, which is part of why buyers choose the style.
• More finger coverage: The side stones spread the design wider than a solitaire without moving to a much larger centre diamond.
• Strong shape pairings: If you already know the centre silhouette, compare oval three stone engagement rings rather than staying on the broader style page.
• Works across stone types: Narrow by material into lab grown diamond three stone rings or moissanite three stone rings.

Compare the centre and side-stone shapes before choosing your trilogy ring. Rosie pairs an oval centre with oval side stones, while Gia uses round side stones. You can compare them on our oval three-stone ring page.

• Start with the centre stone: The centre shape leads the design, and the side stones are then chosen to match it or to complement it.
• Choose the side stone shape: Side stones can repeat the centre shape for a classic look, or use pear, trapezoid or tapered baguette shapes for a more tailored profile.
• Balance the side stone size: Check the dimensions and total weight listed for each design. Its side stones stay the specified size when you change the centre stone, so the proportions change with your selection.
• Read the background first: For shape pairings, side stone sizing and the meaning of the trio, read the three stone ring guide, then use this page to compare rings.
