Collection: Three Stone Engagement Rings

Celebrate your story with IGI Certified Three Stone Lab Grown Diamond Engagement Rings from Unii Jewels. Also known as trilogy engagement rings, three stone designs feature a prominent center diamond accompanied by two side diamonds, creating additional brilliance, balanced proportions and meaningful symbolism. Traditionally associated with the past, present and future of a relationship, three stone engagement rings combine emotional significance with striking diamond presence.

What Is a Three Stone Engagement Ring?

A three stone engagement ring features three prominent diamonds positioned together across the top of the ring. Typically, a larger center diamond is complemented by two smaller side diamonds, although proportions and diamond-shape combinations can vary by design.

Three stone rings are also commonly called trilogy engagement rings. The three diamonds are traditionally interpreted as representing a couple's past, present and future, making the style especially meaningful for engagements, anniversaries and other relationship milestones.

Why Choose a Three Stone Lab Grown Diamond Engagement Ring?

  • Meaningful symbolism: The three diamonds are traditionally associated with your past, present and future together.
  • Additional diamond presence: Side diamonds extend brilliance beyond the center stone and create a substantial face-up appearance.
  • Balanced proportions: Three stones positioned across the finger create an elegant, symmetrical composition in many designs.
  • Multiple diamond combinations: Round, oval, emerald, radiant, pear, princess, marquise and cushion diamonds can be incorporated into three-stone settings.
  • Classic and contemporary versatility: Trilogy settings can range from traditional matched-stone designs to modern combinations of different diamond shapes.

Three Stone vs. Other Engagement Ring Settings

A three stone engagement ring uses two prominent side diamonds alongside the center stone, while a Solitaire Engagement Ring keeps the design focused primarily on a single center diamond.

For designs featuring smaller accent diamonds beside the center stone, explore Side Stone Engagement Rings. If you prefer two prominent center stones rather than three, browse Toi et Moi Rings. For additional sparkle extending along the band, explore Pavé Engagement Rings.

How to Choose a Three Stone Engagement Ring

1. Choose your center diamond shape. Round and oval diamonds offer classic brilliant styling, while emerald, radiant, pear, princess, cushion and marquise shapes create distinctly different silhouettes.

2. Consider the side-stone shapes. Side diamonds can complement or contrast with the center stone. Their shape and proportions significantly influence the overall appearance of a trilogy engagement ring.

3. Compare center-to-side-stone proportions. Larger side diamonds create a more substantial three-diamond look, while smaller side stones keep greater visual emphasis on the center diamond.

4. Choose your precious metal. Unii Jewels three stone engagement rings are available across 10K gold, 14K gold, 18K gold, platinum and selected silver options, depending on the individual design.

5. Consider your wedding band. The width and profile of a three-stone setting can influence how a wedding band sits alongside the engagement ring, so consider your preferred pairing when selecting the design.
