宝石加工機器および試験機器
カッターの作業台にあるものはすべて誰かが作ったものであり、そのほとんどは数十年にわたりこの仕事に携わってきた小規模な企業によるものです。ここでは、誰が何を作ったのかを記録しています。カットや研磨を行う機械、仕上がりを検査する器具、そして誰の手も触れる前に宝石をデザインしたソフトウェアなどです。
当サイトでは、機器のレビューやランキングは行っておりません。 すべての記録はメーカー自身のウェブサイトから収集されたもので、出典ページと閲覧日が明記されています。当サイトにはアフィリエイトリンクは一切なく、掲載料を支払って掲載されることもありません。有名なメーカーが営業を停止している場合は、その旨が記録に記載されています。なぜなら、それが通常、皆様が知っておくべき情報だからです。

宝石のカット方法や検査方法を理解している購入者は、販売業者の商品説明を異なる視点で読み解きます。ここで使用されている測定機器は、検査機関が用いるものと同じもので、ベンチスケール版となっています。また、携帯型テスターで判断できること、できないことを把握することは、どの検査機関が報告書を発行したかを知るのと同じくらい重要なことです。
