※ We strive to ensure that the photos reflect the actual color of the stone, but the appearance may differ slightly from the actual product due to lighting conditions during photography or your monitor settings. Additionally, some photos may be taken using a penlight.
※ For items featuring UV fluorescence photos, the images are taken using a 365nm wavelength blacklight. If you use a light with a different wavelength (e.g., around 395nm), the fluorescence may appear weaker or be difficult to observe. The blacklight used in our shop can be found here.
