The center princess cut is secured by a four-prong trellis basket that keeps each corner protected while leaving the sides open to light. The trellis structure crosses beneath the diamonds instead of using a solid gallery, giving the setting a lighter profile and making the center easier to clean from underneath.
Two matching princess cut side diamonds continue the clean geometry of the center stone, creating a balanced three-stone arrangement with uninterrupted square outlines. The plain comfort shank keeps the focus on the diamonds while providing a smooth fit for everyday wear. Signora Jewels crafts every ring to order in your selected metal and center diamond size.
