Description from the seller
優れた天然エチオピア産ラフオパール。白地に多色の遊色。コレクター向けのトップストーン。
Dimensions from 12.00 mm to 22.00. All pictures are taken with high resolution camera on bone dry material and on different backgrounds in order to depict the opal as realistically as possible.
Worldwide shipping with registered mail and tracking number.
オパールは水分を含むシリカの水和形で、水分含有量は3%〜21%です。実際、水分を含むことがオパールを親水性にする要因です。
オパールは比較的低温で形成され、ほぼあらゆる岩石の亀裂に発生し得ます。リモナイト、砂岩、流紋岩、泥灰岩、玄武岩などとともに見られることが最も多いです。貴石オパールだけが内部色の変化する遊色を示します。
顕微鏡レベルでは、貴石オパールは直径約150〜300 nmの二酸化ケイ素の球が六方最密充填または立方最密充填の格子状に組み合わさってできています。これらの規則的なシリカ球が、オパールの微細構造を通過する光の干渉と回折を引き起こすことで、内部色を生み出します。」} }{
