這些是實驗室培育鑽石,採用CVD(化學氣相沉積)方法在實驗室中培育。在此過程中,鑽石在真空環境中由碳氫化合物氣體和氫氣的混合物中生長。實驗室培育鑽石作為「符合道德的鑽石」和「可持續鑽石」獲得了支持,因為它們緩解了人們對與天然鑽石開採相關的環境和社會問題的擔憂,並且它們代表了為子孫後代提供可持續寶石供應。此外,雖然由於合成技術的進步,質量已大大提高,但生產成本卻逐年下降,與天然鑽石相比,它們的價格顯著降低,這是另一個吸引人的特點。

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.
