未鑽孔 (裸石)
顏色：藍綠色
這是一顆圓形刻面合成亞歷山大石。它是使用「柴可拉斯基法」(晶體拉製法) 製造的，該方法應用半導體技術來生長超純單晶。其最顯著的特點是其戲劇性的顏色變化。在自然光下，它呈現深藍綠色，而在白熾燈下，它鮮明地轉變為紅紫色 (第三張圖片是在白熾燈下拍攝，第四張圖片則使用黑光 (峰值波長395nm) 拍攝)。作為用於珠寶的裸石，其透明度和顏色都無可挑剔。由於它是一種未鑽孔的類型，因此非常適合鑲嵌和其他加工。已鑑定出另一種尺寸，結果為「合成亞歷山大石」。
出貨時顏色和尺寸將混合。

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.
