Product DescriptionThis professional three-dimensional digital asset features a refined solitaire ring concept characterized by a flowing, bypassing ribbon shank that gracefully embraces the central setting. Engineered from the ground up with precise focus on production constraints, the elegant crossover lines provide a fluid, seamless aesthetic while ensuring structural stability and balanced weight distribution for bench jewelers and manufacturers.

The central setting utilizes a secure five-prong configuration designed specifically to protect the delicate tip of a teardrop or pear-shaped geometric stone layout while maintaining maximum light entrance to optimize brilliance. This model is engineered to serve multiple professional pipelines, making it ideal for direct investment casting, high-fidelity photorealistic rendering, commercial visualization portfolios, and master pattern prototyping.

Technical Details and DimensionsThe geometry has been thoroughly inspected to guarantee flawless manufacturing workflows and structural durability.

Ring Size: US 6.5 (Internal ring diameter optimized for standard sizing adjustments)

Center Setting: Configured for one teardrop-shaped gemstone measuring approximately 8.50 mm x 5.50 mm

Setting Mechanics: 5-Prong wire setting layout incorporating a protective V-prong at the vertex

Setting Elevation: 4.50 mm clearance measured from the internal finger profile to the setting base

Band Thickness: 1.60 mm uniform depth at the base profile

Band Width: 2.00 mm width at the base, tapering elegantly to 1.70 mm at the twisting shoulder profiles
