這是一種美麗的混合寶石，努烏邁特石（也稱為Nuummit或Astrophyllite），黑色，具有玻璃光澤。根據一位寶石學家的說法，它是一種由多種礦物組成的混合寶石。一份不同形狀的獨立鑑定報告列出了三種主要礦物：「直閃石」、「石英」和「十字石」。鑑定結果列出單一礦物的三個名稱是非常罕見的。寶石學家還提到它含有「石榴石」的成分。這種寶石顏色豐富，底色為黑色，有石英的透明區域，其他礦物的棕色和灰色區域，以及線狀、彼得石般的光澤閃爍，以及金色內含物。

All images are photographs of the actual items. For products that do not vary in quality, images taken previously may be used.
We strive to present images without any correction whenever possible. However, due to camera characteristics, colors may appear more vivid than in reality, or in cases where the color tone is judged to differ significantly from the actual item, adjustments may be made solely to bring the color closer to the real appearance. (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.
