14K yellow gold. Solitaire is 1ct round cut diamond. Jacket has 0.25ct total diamonds small round cut. Size 5.5 but can be resized. (The infinity rings are not included). Absolutely gorgeous when all cleaned up. I have taken really good care of them and cleaned them often. New they were $6500, appraised at $4500. Willing to meet in Okc, Yukon, Mustang, or Edmond.
