An opal is a hydrated form of silica with a water content ranging from 3 to 21%. Indeed, it is this permeability to water that makes it a hydrophile.
オパールは含水量が3%から21%のシリカの水和形です。実際、水分を含む性質がこのオパールを親水性たらしめています。
Opals are deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt. Only precious opals show a variable interplay of internal colors.
オパールは比較的低温で堆積し、ほとんどすべての岩の亀裂に生じ得ますが、最もよく見られるのはリモナイト、砂岩、流紋岩、泥灰岩、玄武岩と共に見られます。内部色の変化を見せるのは、貴石オパールだけです。
At microscopic scales, precious opal is composed of silica spheres some 150 to 300 nm in diameter in a hexagonal or cubic close-packed lattice. These ordered silica spheres produce the internal colors by causing the interference and diffraction of light passing through the microstructure of the opal.
顕微鏡レベルでは、プレシャスオパールは直径約150~300 nmのシリカ球が六方最密充填(六方最密格子)または立方最密格子の配列を成しています。これらの整列したシリカ球が、オパールの微細構造を通過する光の干渉と回折を生じさせ、内部の色を生み出します。
