This is an amazing ring set in 18K yellow gold. It features a double-twisting rope of gold surrounding sapphires, rubies, and diamonds. There are 20 sapphires: totaling approximately 0.7 carats, 20 rubies: totaling approximately 0.7 carats, and 10 diamonds: totaling approximately 0.3 carats for a total of 1.7 total carats. This ring is currently a size 3.75, but has sizing bars currently built into the band. They could be removed and, after removal, the ring would be around a size 7. A size outside of that range would be difficult to get to, due to the eternity style of the design. This piece is in excellent used condition. Plus, lots of gold in this piece, weighing just over 12.5 grams. Certainly a unique piece that would be a great addition to any collection.
