I received six rocks in my purchase order all as expected, and I will use mineral box again

ナミビアのツメブ鉱山産、漆黒の電気石の柱状結晶です。結晶面には深い条線が刻まれ、ガラス質の強い光沢を放ちます。根元からは小さな板状の結晶が扇のように開いています。透明アクリルブロックに立てて高さ6.1 cm。
この結晶の見どころは、何よりもその黒さです。ずんぐりとした柱が一本、芯まで不透明で、面には電気石特有の深い縦の条線が刻まれています。艶が強く、稜のひとつひとつに白いハイライトが鋭く走ります。その肩にはもう一回り小さな柱が寄りかかり、根元からは板状の結晶が扇のように開き、左下の側面にはクリーム色がかった白い粒が点々と付着しています。
電気石は単一の鉱物ではなく、ホウ素を含む珪酸塩の一族です。鉄に富む黒色のものは、そのなかで最もありふれた存在にあたります。硬度は7から7.5あり、家庭で付く程度の傷はほとんど寄せつけません。三方晶系の対称性は、平らな面で囲まれた柱と、鑿で浅く削いだような錐面にはっきり現れています。焦電性をもつことでも知られ、結晶を温めると両端に逆の電荷が生じます。
高さ6.1 cm、底面は5.1 × 3.6 cm、重量96 g。透明アクリルブロックの上に立てた状態でご紹介しています。掲載写真はすべてこの結晶を撮影したものです。
