Excellent antique condition. This incredible turn of the century piece features 8 all natural tested genuine rose cut diamonds, prong set into solid 18kt yellow gold and making up the necklace and tiara of the beautiful habillé cameo subject of the pendant. Each diamond is original to the piece and measures at least 1.5mm in both directions with largest measuring approximately 2.3mm x 1.5mm. There is a hallmark present at the base, likely the French eagle indicating 750 (18k) but it is difficult to fully make out. Weight is 3.64 grams. Please see photos for measurements in inches.
