Description from the seller

オロ 18金のビンテージ「バレリーナ」リング、ブルーサファイアとダイヤモンド(ブリリアントカットと baguette)をあしらったホワイトゴールド、私のおばのコレクションから。1920年代に着用。リングは良好な状態です。
中央の青い石はサファイアのオーバル/クッションカットに似た形で、約8–10 mmの長さ、約6–8 mmの幅。これらのサイズから、サファイアはおおよそ2–4カラット程度と考えられ、特に石の深さによって変わります。
中央石:約2.50 ct。
周囲のダイヤモンド:トータル約1.20 ct。
ダイヤモンドの色(白さのスケール)。
ダイヤモンドのクオリティ:内包物が小さく見られます。

周囲には複数のダイヤモンドがセッティングされており、いくつかは丸形、少なくとも2つは baguetteカット。肉眼では、ダイヤモンドの総重量は約0.8–1.5 ct程度と推定されますが、この部分は写真だけでは難しい鑑定です。

したがって、もし:
・ホワイトゴールド18Kの台座またはプラチナ製
・天然サファイア約2–4 ct
・天然ダイヤモンド約1 ct以上
