Thank you for contacting Mearto with your appraisal inquiry. This is a Tacori solitaire engagement ring made likely in the early 2000's in Los Angeles, California. The ring is made of 18 karat gold. This piece is in good condition, with some scratches and scuffs present on the gold. All of the stone-settings appear sound and intact, with none of them missing. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 1,800-1,900 dollars. Please reach out with any questions. Bo Stuck
