Striking geometric lines give this 14K yellow and white gold semi-mount engagement ring an elegant, vintage-inspired character. The setting is shown with a 1.50 carat emerald cut cubic zirconia center placeholder, secured by contrasting white gold prongs to emphasize the crisp step-cut silhouette. Six natural accent diamonds totaling 0.25 CTW in H color and SI clarity create a beautifully balanced arrangement along the shoulders, combining sparkling round diamonds with elongated tapered-cut diamonds that gracefully draw the eye toward the center stone. Warm yellow gold adds richness and contrast to the bright white diamond settings, while the mixed diamond shapes create a sophisticated look reminiscent of classic Art Deco jewelry. Designed to be personalized with the emerald cut center diamond or gemstone of your choice, this semi-mount offers a distinctive combination of two-tone gold, architectural lines and timeless diamond brilliance.
