Rare Gerochristo Cyclades Faith Navigation Ruby 10K Vermeil Ring Sz 4.5

Absolutely incredible and exceptionally rare vintage estate Gerochristo ring from the Cyclades collection. Estate records identify this as the Gerochristo Cyclades Faith Navigation Ring, crafted in silver with a 10K gold vermeil exterior and a rich red ruby cabochon centerpiece. The heavy sculptural construction, ancient Greek influence and dramatic geometric design give this little size 4.5 ring an enormous presence. Gorgeous as a pinky, signet or statement ring and a truly unusual Gerochristo collector piece.  The original interior maker’s marking has worn to the point that it is no longer legible. Identification, ruby attribution and 10K gold vermeil designation are according to the estate records. The gold exterior acid/stone tests at approximately 10K. Gemstone identity, internal metal composition and maker attribution have not been independently authenticated. I’m offering my good faith description based the estate records available to me. ❌ review all photos as part of the description.❌ please do not ask for further authenticity as I have already given you everything I know.
