This three stone engagement ring pairs a 1-carat emerald cut lab-grown diamond center stone with two tapered baguette diamonds for a streamlined, architectural profile.

  • 1.8mm band width \u2014 offers a slender, comfortable profile for everyday wear.
  • Bar-set tapered baguettes \u2014 flank the center stone (0.46 ct. tw.), each held securely along its length for a smooth, linear edge.
  • Three stone design \u2014 builds visual weight on either side of the center diamond without a raised halo.
  • Refined setting \u2014 keeps the shoulders sleek so the eye moves easily from the band to the center stone, shaped to keep the setting compact and the center stone as the focal point.
  • D-F color, VS clarity \u2014 grading keeps the center stone bright and clear.
  • Precious metal options \u2014 let you choose the one that suits your style.

This center lab diamond is certified for authenticity by an independent grading lab and inscribed with a number that matches its certificate.

What customers are saying

Customers love how this ring takes the classic three-stone design and makes it feel both elegant and unique, with the baguette side stones giving it a timeless antique quality. The setting complements emerald and oval center stones beautifully, and wearers say it looks stunning on petite hands without overwhelming the finger. Many describe it as the kind of ring they find themselves staring at constantly because the sparkle is hard to ignore.

Stunning Ring

I am absolutely in love with my engagement ring! My fiancé and I went to a show room to look at rings, and this was on my wish list. I love how classic it looks, and it's not as common as a simple band engagement ring. I chose an emerald cut center stone. The only negative is that we chose 18k gold for the metal, so that means it is very soft and will scratch easily. The scratches aren't noticeable, but if you worry about that, maybe choose a different metal. ...Read More
