Asscher-Cut Center
The 7.00 × 7.00 mm square Asscher-cut diamond showcases precisely aligned step-cut facets and the distinctive hall-of-mirrors optical effect associated with this vintage-inspired shape
Art Deco Geometry
The square outline and concentric step-cut pattern create a refined geometric character inspired by classic Art Deco jewelry
Cross-Over Cathedral Architecture
The band fluidly sweeps upward and crosses beneath the center stone, forming an integrated architectural foundation for the 4-prong basket
Protective 4-Prong Basket
A precision-formed four-prong setting securely holds the center diamond while providing protection around its cut corners
Minimalist Plain Shank
The smooth 2.00 mm high-polish gold band creates a clean solitaire profile and allows the Asscher diamond to remain the visual focal point
Wedding-Band Compatibility
The elevated setting is engineered to accommodate a straight wedding band in a flush-fitting configuration
