This amazing ring has natural channel set rubies and diamonds set in solid platinum with a white gold shank weighing 4.8grams total.
The ring is a size 7.5 and it's sizeable.

* The face of the ring is 17.4mm in diameter. My finger is a size 5 for comparison. The outside diameter of the center bezel set diamond is 5.4mm

*The center is 4.8mm*3.25mm weighing by formula an approximate of 0.45ct . This diamond is bright and near colorless ( G-H) with a just slightly included clarity ( SI1) . Eye clean and gorgeous. And additional estimated 0.25ct of diamond melee is spread around the ring, with similar color and clarity.

* Approximately 2ct of rubies on the ring. The ring could use a polish as the platinum has dulled with age as it's common on these older rings, but I'll leave that up to the buyer. There are minor nicks on some of the rubies under magnification. Overall beautiful ring in great condition, look at that gallery, work of art.
