I actually have "the works" on this ring: This amazing estate ruby ring is finely crafted in solid 18K yellow gold. The ring is set with high quality genuine earth mined rubies and diamonds. Thirty six french cut channel set rubies measure about 2mm each for the total 1.80 carats. These rubies are very clean and transparent gems of great intensity and strong brilliance. The pear cut ruby measures 6mm x 5mm (.50 carat). Ten white and fiery diamonds are estimated to be VS-1 clarity and GH color for the total weight .08 carat. The top of the ring measures 16mm north-south, the band is fitted for a size 8, and this tremendous piece of estate fine jewelry weighs 10.0 grams. Great condition.
