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

深い条線を刻んだずんぐりした黒色電気石の柱が、一点から放射状に開くナミビア産の標本です。結晶の隙間にはクリーム色の粒状の皮殻が中央を縫うように入り込んでいます。自然のままの未研磨品で、5.1 × 4.1 × 3.3 cm、50 g。アクリル台付き。
ずんぐりとした黒い柱が数本、一点から車輪のスポークのように放射状に開いています。柱面には電気石特有の深い縦条線が刻まれ、群晶を回すごとに光の返り方が変わります。畝のような側面ではサテンのように柔らかく、無傷で残った錐面ではガラスに近い輝きに。クリーム白の粒状の皮殻が結晶の隙間に食い込みながら、放射の中心を縫って立ち上がっています。
電気石はホウ素を含む珪酸塩鉱物で、三方晶系、硬度は7〜7.5。黒い変種の色は鉄に由来します。圧電性と焦電性の両方を備えた数少ない鉱物のひとつで、結晶を温めると両端に逆の電荷が生じます。棚に長く置いた標本が、どれだけケースを清潔にしていても埃や糸くずをまとってしまうのはそのためです。
5.1 × 4.1 × 3.3 cm、50 g と、手のひらに収まるほどよい大きさです。画像にある透明アクリルのブロックに、取り外せる粘着パテで留めた状態でお届けします。写真はこの群晶そのものを撮影したものです。
