For your consideration is this gorgeous ruby diamond slider pendant. Done in 14kt and marked as such. It has 10 3.5 X 2 mm wonderful marquise cut natural rubies and 10 tiny diamonds. I am not a jeweler but the internet chart I used puts this at about a carat of rubies. Purchased from a friend who's wife had it for many many years. I did clean the piece.
It measures just shy of 7/8 inches by 7/8 inches.
Excellent condition and even prettier in person as it is difficult to capture the sparkle of the diamond. Rubies are a great pink red color.
