Description from the seller
このマダガスカル産の赤瑪瑙は、自由形状のまま研磨加工され光沢を添えられた天然の装飾要素として視覚的にも物質感を強く放つ。標本は調和の取れたがっしりとした形を保ち、ボリュームのある充実した形と、優しく丸められた表面がその彫刻的な性格を際立たせつつも、元の地質学的起源を歪めてはいない。研磨は石の内部構造を際立たせ、色の深さと柔らかな光沢を与える。色調は錆色がかった暖かい赤、濃い赤、オレンジがかった褐色の間で移り変わり、滑らかな移行と、強くシリ化された赤い玉髄を連想させる部分の濃度の差がある。いくつかの箇所では色の濃淡がさらに濃くなり、内部に薄い筋状の脈が見られ、長い時間をかけて起きた多重のシリケーションの過程を物語っている。これらの構造は、元々多孔性で微小な亀裂を有する物質が、徐々にシリカを豊富に含む溶液によって浸透され、緻密で頑丈な塊へと変化したという複雑な形成過程を示唆している。マダガスカルはシリケート形成で知られ、しばしばアゲート(瑪瑙)、ディアスパー、塊状カルセドニーの境界付近に見られることが多い。
