Oval Tulip Four-Prong Cathedral Lab Grown Diamond Engagement Ring in Yellow Gold
Elegant from every angle, the Oval Tulip Four-Prong Cathedral Lab Grown Diamond Engagement Ring in Yellow Gold by Sphere Diamond combines a brilliant oval lab grown diamond with a graceful tulip-inspired basket and classic cathedral shoulders. The warm yellow gold band creates a refined contrast with the bright center diamond, resulting in a timeless engagement ring with a distinctive architectural profile.
Designed for those who appreciate meaningful details, the tulip-inspired setting forms delicate curves around the center stone when viewed from the side. Four carefully positioned prongs secure the oval diamond while allowing its elongated silhouette and brilliance to remain the focal point.
Oval Cut Lab Grown Diamond
The oval cut combines an elegant elongated outline with brilliant-style faceting. Its balanced proportions create a graceful appearance on the finger while delivering impressive sparkle, making an oval lab grown diamond engagement ring a popular choice for modern proposals and timeless bridal jewelry.
Tulip-Inspired Four-Prong Setting
The center diamond is held by a four-prong setting shaped with graceful, petal-like curves inspired by a blooming tulip. This distinctive basket adds visual interest beneath the diamond without distracting from the center stone, giving the ring an elegant profile from both the front and side.
Classic Cathedral Setting
The cathedral-style shoulders rise gently toward the center setting, visually framing the oval diamond and creating a smooth transition between the polished band and the tulip basket. This architectural detail adds height and dimension while maintaining a refined, classic appearance.
Warm Yellow Gold Design
Yellow gold brings warmth and timeless character to the design. Its rich tone creates a beautiful contrast against the brilliance of the oval lab grown diamond, making this ring an elegant choice for those who appreciate classic precious metal with a contemporary diamond setting.
