Portland is an exceptional authentic Late Victorian era (circa 1895) silver topped 18k yellow gold engagement ring. This antique cluster ring centers a four-prong set EGL certified 0.89ct Old Mine Cut diamond graded K color and VS1 clarity. The center diamond is framed by a cushion shaped halo of sixteen Single Cut diamonds totaling approximately 0.40ct. The accent stones are each individually set within silver bezels, creating a lovely scalloped edge around the ring. Portland sits extremely low to the finger and is finished with a newer 14k yellow gold shank that was most likely added in the 1940's. The ring is currently a size 5.75 and can be sized to fit.
