Our Trilogy Engagement Ring collection contains rings composed of three exquisitely cut diamonds. These combined together form an absolutely stunning engagement ring that will make you the envy of all your friends! You'll find trilogy rings with princess cut (square) diamonds, brilliant cut (round) diamonds, as well as many others. The rings are available in a choice of white gold, palladium, platinum and more!

Choosing a Diamond

With our trilogy engagement rings, you can choose the cut, clarity, color, and carat of the center diamond, and we will match the accompanying side stones accordingly. All center stone diamonds over 0.25 carats in weight are automatically provided with a certificate. If you'd like the side stones to be certified, please contact us.
