Beautiful 14k white gold with yellow gold accents. 6 prongs hold Marquis center diamond. Jeweler says center diamond just shy of 1 carat. Surrounding diamonds total approx 1 carat also. Larger round diamonds on both sides of Marquis and 4 smaller round channel set diamonds on each side of ring. Nice heavy ring. Marked inside. Very shiny and eye catching! I believe it's size 7.5
