The stepped facets of the Asscher cut lab-grown diamond create an intriguing geometric pattern that catches light through the open gallery design. Wearers will appreciate how the tapered band highlights the focal trio while maintaining a smooth, balanced feel against the finger.

Crafted as a dedicated three-stone arrangement, this ring highlights a central Asscher cut lab-grown diamond flanked by two matching side stones. The step-cut center stone displays crisp, parallel facets that create an unique mirrored depth. Four sturdy prongs hold each gem safely in place while keeping the silhouette balanced. Below the stones, an open gallery construction increases light exposure from all sides, elevating the visibility across the top portion. The shoulders taper cleanly as they meet the focal point, creating a slimming optical effect along the finger. Further down, the ring transitions into a comfortable round shank finished with a reflective high polish. Designed without additional accent stones, the focus remains entirely on the structural layout. Select your preference from white gold, rose gold, yellow gold, silver, or platinum to suit your personal style.
