Solid 18k Gold, 8 Ct Diamond Ring, Late 1800's Early 1900's, Collectors Piece

This ring is very hard to let go of, but I have not worn it in many years, so I'd love to see it go to someone who can appreciate it's beauty, and enjoy it! Solid 18k yellow gold with white gold accents, adorned with over 60 genuine, mine cut & European cut diamonds. This piece has beautiful twisted wire detail, which was common in the designs of Jean Schlumberger, Buccellati, Graff, David Webb, and Van Cleef & Arpels. This ring has similarities with pieces from France, however it's origins are unknown. There are two hallmarks/makers marks, however after bringing it to 4 jewelers, we have not been able to decipher them. So, I am selling this gorgeous ring (that photos do NO justice for) as an amazing, museum quality antique piece, that is sure to turn heads anywhere you go. Due to the rarity & value of this ring, no returns will be accepted. This ring will go to Poshmark to be inspected & authenticated prior to the buyer receiving it, for peace of mind. Please keep in mind Posh takes 20% of all sales. Low offers will not be entertained. Please look up other similar rings to determine the value, as this ring is priced very fairly. Thank you!
