Antique French 16K Yellow Gold 2.22CTW Diamond Halo Ring | Historic Provenance

This rare antique statement ring is a remarkable piece of historical fine jewelry, crafted in solid 16k yellow gold and displaying a bold, architectural halo silhouette. 
What makes this piece extraordinarily unique is its historical provenance: crafted in France during an era of economic recession, French jewelers adjusted traditional 18k standards down to 16k gold (66.6% purity). This historic alloy gives the ring a distinctive warmth and rich legacy that sets it apart from standard modern castings.
At its center sits a substantial 1.01ct round brilliant-cut diamond (approx. 6.50 mm diameter) exhibiting bright life and fire. It is framed by a seamless geometric halo of 10 channel-set princess-cut diamonds (1.21ctw) with high clarity (VS1–VS2) and crisp G–H color, bringing the total diamond weight to an impressive 2.22ctw.
