This solitaire engagement ring by Filigree features a 2.35 carat cushion cut spinel in a dark grey-purple color, set in 14 karat yellow gold. The spinel displays an unusual color that shifts between charcoal grey and deep purple depending on the lighting. Cushion cuts have rounded corners and larger facets that show off the stone's color saturation.

The stone sits in a four-prong basket setting above a 3.25mm wide band with flat edges. At 2.35 carats, the spinel has significant presence without sitting too high above the finger.
