The combination of an elongated marquise center lab-grown diamond and tapered shoulders creates a striking length along the finger without adding bulk. Someone seeking a refined three stone style with structural basket protection will appreciate how comfortably this smooth, high polish band rests on the hand.

Built around a three stone profile, this ring features a focal marquise lab-grown diamond flanked by two supporting lab-grown diamonds. An open basket setting elevated off the band allows light to reach every angle of the stones, while twelve individual prongs ensure firm, reliable setting security. The architecture transitions gracefully into tapered shoulders that narrow as they meet the focal point, creating a balanced visual contour on the finger. Below, a smooth round shank provides structural integrity and a fit during everyday wear. Finished with a high polish that catches light along the metal curve, the piece contains no extra accent stones, keeping full focus on the main lab-grown diamonds. Select your preferred metal from yellow gold, rose gold, white gold, silver, or platinum to complete the design.
