Radiant Cut Lab Grown Diamond Side Stone Engagement Ring with Marquise and Round Eternity Band

An elongated radiant cut lab grown diamond center is held in a four-prong basket with an open split-rail gallery. Alternating marquise and round side stones are set in shared prongs around the full eternity band, with the marquises oriented east-west for a flowing, rhythmic line. The photos show a two-tone treatment with a white gold center setting on a yellow gold band, and the design can also be made in rose gold or a single metal throughout. The slim band keeps the focus on the rectangular center while adding light along the finger. Each ring is custom made in your choice of 10k, 14k, or 18k gold, or platinum.
