The oval center diamond is secured within a classic four-prong cathedral basket that protects the stone while allowing generous light to enter through the open gallery beneath. Its elongated silhouette enhances finger coverage and showcases the balanced brilliance of the oval cut.
Marquise and round brilliant accent diamonds decorate each shoulder in a graceful botanical arrangement that leads naturally toward the center stone. The slim comfort shank keeps the profile refined while allowing the side accents to complement, rather than compete with, the solitaire design.

About Lab Grown Diamonds
The oval cut is prized for its elongated silhouette and exceptional brilliance. Marquise side diamonds echo its graceful proportions, while the round brilliant accents add subtle sparkle that enhances the overall composition without overwhelming the center stone.
Metal, Care & Fit
Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the cathedral basket and around the marquise and round accent diamonds using warm water, mild soap and a soft brush to maintain brilliance.
