About this product

The Bloomingdale's Fine Collection offers an elegant 18K white gold engagement ring featuring a certified lab-grown cushion-cut diamond center stone. The solitaire is set atop a pavé band, with the entire piece crafted using precision techniques that mirror those used for natural diamonds. The lab-grown diamond has a total carat weight of approximately 4 to 5.5 carats and is graded F color and VS2 clarity. White gold is rhodium-plated for enhanced shine, though re-plating may be needed over time due to wear. This ring represents a modern alternative to mined diamonds, matching natural stones in physical, optical, and chemical properties.
