Design Features

Round Brilliant Center
The 8.00 × 8.00 mm round brilliant-cut diamond is selected for strong fire, brilliance, scintillation, and balanced optical performance
4-Prong Cathedral Setting
Sweeping cathedral shoulders transition into a secure four-prong basket, providing structural support while maintaining an open and elegant presentation of the center diamond
Classic Solitaire Shank
The smooth 2.00 mm high-polish gold band creates a clean and timeless silhouette without competing with the center stone
Elevated Profile
The cathedral setting creates a refined elevated profile while providing space for a straight wedding band to sit flush against the engagement ring
Classic Meets Contemporary
Traditional solitaire proportions are combined with precision-engineered architectural construction for a modern fine-jewelry finish

Form-Fitted Basket
