Description from the seller
Royal Antwerp Gem – Natural Pinkish-Red Ruby – 1.64 ct – Tajikistan – No Heat – GRS Swiss Lab Certified
⸻
DESCRIPTION
1.64 ctの魅力的で飽和したピンク〜赤の色味を示す、個性のある天然ピンク指紅ルビー。カ ボルにはクラシックなオーバル形状とブリリアント/ステップカットが施され、エレガントな外観と生き生きとした色を際立たせます。
この宝石は、スイスのGRS GemResearch Swisslabによって検査・鑑定されています。GRSのレポートによると、産地はタジキスタンで、宝石品質ルビーとしては珍しく、あまり一般的ではない産地です。
重要な点として、レポートには「熱処理の兆候なし」と記されており、無熱処理であることが確認されています。
GRSのレポートには「(オイル処理済み)」およびFTIR検査済みと記載されています。よって、油処理はラボの所見に基づいて完全に開示されています。
1.64 ctの重量、珍しいタジキスタン産、無熱処理、ピンク〜赤色、GRS認証の組み合わせにより、本 gemstone コレクションやオーダーメイドジュエリーにとって興味深いルビーとなっています。
