3 Carat Marquise Tulip Cathedral Lab Grown Diamond Engagement Ring in Yellow Gold
Elegant and distinctive, the 3 Carat Marquise Tulip Cathedral Lab Grown Diamond Engagement Ring by Sphere Diamond showcases an elongated marquise-shaped lab grown diamond in a sculptural tulip-inspired setting. Crafted in yellow gold, the design combines a graceful cathedral profile with delicate petal-like details that beautifully frame the center diamond.
The 3 carat marquise diamond creates an elongated silhouette with two elegant pointed ends, offering impressive finger coverage while maintaining a refined appearance. From the side, the tulip-inspired basket rises naturally from the cathedral shoulders, creating a distinctive architectural profile and allowing the center diamond to remain the focus of the ring.
3 Carat Marquise Lab Grown Diamond
The marquise shape is known for its elongated proportions and distinctive pointed silhouette. A 3 carat marquise lab grown diamond creates strong visual presence on the hand and is an elegant alternative to traditional round or oval engagement rings.
Tulip-Inspired Diamond Setting
Viewed from the side, the setting features graceful petal-inspired elements that rise toward the marquise center diamond. The tulip setting adds a romantic design detail while creating an elegant profile from multiple viewing angles.
Cathedral Engagement Ring Setting
The cathedral-style shoulders sweep upward toward the center setting, visually connecting the yellow gold band with the marquise diamond. This classic structure gives the ring an elegant transition from the band to the center stone while emphasizing the height and presence of the diamond.
Yellow Gold Engagement Ring
The warm tone of yellow gold creates a sophisticated contrast with the bright appearance of the marquise lab grown diamond. The polished band keeps the design refined and allows the center diamond and sculptural tulip setting to remain the main focal points.
