Optimized for manufacturing and stone setting, this model includes carefully balanced dimensions for strength and refinement:

Prong thickness: 1.60 mm

Band thickness: 1.88 mm

Delivered as a complete engagement ring set, this design is ideal for custom production, bridal collections, and B2B jewelry manufacturing.
