這些是來自印尼爪哇島的阿格尼瑪尼石圓珠。阿格尼瑪尼石作為在印尼新發現的隕石撞擊起源的天然玻璃「玻璃隕石」廣泛分佈。然而，其中大部分實際上是火山噴發起源的天然玻璃「黑曜石」。我們認為，這種誤解的發生是因為阿格尼瑪尼石原石不像典型的黑曜石那樣以大塊形式存在，而是以與玻璃隕石非常相似的小塊個體形式存在。
由於印尼的地域特性，稀有地混入玻璃隕石是可能的。然而，採礦者在沒有對每個個體進行成分分析的情況下，不可能區分玻璃隕石和黑曜石，因此大多數廣泛分佈的阿格尼瑪尼石都被認為是黑曜石。我們嘗試從三個不同的來源獲取阿格尼瑪尼石，包括加工前的原石，所有鑑定結果均為黑曜石。先前的鑑定結果為「天然玻璃（黑曜石）」。
無論如何，它仍然是一種稀有的天然玻璃，具有獨特的外觀，類似於捷克隕石和玻璃隕石，並以「Agnimanitite」的商品名稱受到珍視。因此，我們將繼續將其作為印尼阿格尼瑪尼石出售。

(We do not perform any adjustments intended to enhance color vibrancy.)
Please use the listed product sizes as a general reference. We disclaim responsibility for minor size variations or differences between individual items.
Due to the nature of natural stones, items may contain small scratches, inclusions, or minor chips that occur during processing or transportation. These are not eligible for compensation or exchange.
For items sold per bead, pieces with minor scratches, chips, inclusions, distortions, or chipped drill holes may be included. We do not provide individual compensation or exchanges when multiple beads are sold. (For example, if one bead out of a set of three has a flaw, we cannot offer compensation or exchange on a per-bead basis.)
We disclaim responsibility for small (or minimal) scratches or chips that cannot be fully captured in images.
As natural stone beads and loose stones are primarily sold in strands or multiple-piece sets, we do not conduct detailed inspections of each individual piece.
Product descriptions and quality gradings of natural stones are based on our subjective evaluation. They are not absolute or universal standards, so please make your own judgment based on both the description and images.
Due to the nature of natural stones, even within the same grade or lot, there may be variations in size, color, and quality within what we consider the same lot.
If the hole size is unclear, it is not listed in the description. (In most cases where it is not specified, silicone cord will not pass through, so please use wire or similar materials.)
Even when a hole size is provided for natural stones, it is only a guideline and not guaranteed.
