AI-assisted summary
Description from the seller
コバルトブルーの天然スピネル（DEEP BLUE）4.11ct – タンザニア／マヘンゲ – 未加熱 – Lotus Gemology 認定
Magnifico spinello naturale blu del peso di 4,11 carati, accompagnato da prestigioso report gemmologico Lotus Gemology Gold, uno dei laboratori internazionali più apprezzati nel settore delle pietre di colore.
宝石は日光の下で透明な青色を呈し、彩度は中程度、深い色調との記述。エレガントなアンティーク・クッション・カットで、クラウンはブリリアント・カット、パビリオンは段状に改良された構造を組み合わせ、色の深さを引き立て、魅惑的な青い反射を生み出します。
ラボはこの石を日光の下で透明な青色、彩度中程度、深い色調と記述しています。最も重要な点は、加熱や処理のいかなる兆候もないことです。したがって人工的に色が変更されていない天然のスピネルであり、コレクターや鑑賞家に特に評価される特徴です。
10.75 × 8.63 × 5.33 mmという堂々たるサイズと、4カラットを超える重量は、石に重要な存在感を与え、宝石コレクションはもちろん、カクテルリング、ペンダント、またはハイジュエリー作品としても理想的です。
Lotusの報告書はさらにタンザニア産であることを証明しています。タンザニアは大きな魅力と品質を備えたスピネルの産地として知られています。出所は有名なマヘンゲ鉱山の可能性が高いとされます。
力強く、エレガントで現代的なキャラクターを持つ宝石で、重要なサイズ感、深い色、出自の証明、そして加工なしの完全な無処理を一つに備えています。

A Lab Report contains only the characteristics of an article described after it has been graded, tested, examined, and analyzed using the techniques and equipment used at the time of the examination from that specific Lab.
