Cobalt Spinel Special
おはようございます、ノリちゃんです。 ~前置き~ GemTreeJapanでは、2024年のベトナム進出、開拓により幾つものサファイアやスピネル、その他の宝石たちをカットしてきました。その中に青く輝く宝石があります。 イルモさんから「ベトナムに行く。」という話が最初に出た時に、ノリちゃんは既にコバルトスピネルの要望を出していました。他産地でのコバルトスピネルは勿論把握していますが、トッピンと言えるネオン感激しく感じるベトナム産は外せません。 現地へ赴いた上でイルモ-ノリ間でのコンタクトを取ると、予想はしていましたが、中間業者を通さず現地で購入するにしても、綺麗な物は希少で非常に高い価値による高値でより取引されている報告を頂きました。 今ではベトナム産の他にタンザニア産も扱っています。 折角なので、このコバルトスピネルというのはどういう物なのか。記事に起こしてみましょう。 ~鉱物としてのコバルトスピネル~ 上の写真は鉄&コバルト(ベトナム)/コバルトのみ(ベトナム)/コバルトのみ(タンザニア)の3石です。含まれている元素や割合、産地によって様々な色合いがあります。 このコバルトスピネルとは何でしょうね?一般的にはスピネルにコバルトが入り、鮮やかな青色の発色をしたものを差しています。...
