Rated Excellent on Trustpilot.
Four Ethiopian opal specimens from Wello, Ethiopia, weighing 8.48 g in total and measuring between 18 and 26 mm.
Description from the seller
Excellent Natural Ethiopian Rough Opal。白地に多色の輝き。コレクター向けのトップストーンです。
Dimensions from 18 mm to 26 mm. 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.
世界中への発送は、登録郵便と追跡番号付きで行います。
オパールは、水含有量が3%から21%の水和型シリカです。実際、水への浸透性があるからこそ、これを親水性と呼びます。
オパールは比較的低温で沈着し、ほぼあらゆる岩石の割れ目に生じ得ます。最も一般的にはリモナイト、砂岩、流紋岩、泥質灰岩、玄武岩とともに見られます。貴石オパールだけが内部色の可変的な相互作用を示します。
顕微鏡レベルでは、貴石オパールは直径約150〜300nmのシリカ球が六方最密充填または立方最密充填の格子を成しています。これらの規則正しいシリカ球は、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ることにより、内部色を生み出します。
