3.58 Oval Step Cut Cognac Diamond 18k Yellow Gold

This 18 karat yellow gold solitaire holds a 3.58 carat oval step cut natural brown diamond in a four-prong compass setting. The oval step cut creates a hall-of-mirrors effect with its rectangular facets, showcasing the diamond's brown color in broad flashes rather than hiding it with sparkle.

Brown diamonds range from light champagne to deep cognac, and this stone's vivid brown means it has strong, saturated color rather than a pale tint. At VS2 clarity, any inclusions are minor and difficult to see without magnification. 

The 2.8mm yellow gold band provides a warm backdrop that complements the brown diamond, and filigree detailing adds texture to the shoulders. The compass prongs are set at north, south, east, and west positions, creating an X-shape when viewed from above.
