These are 15mm+ blue sapphire beads, which are not usually sold individually. However, due to their size, there may be imperfections such as difficulty in successful impregnation, chips, and white inclusions. To convey how difficult it is to find large, near-perfect specimens, we are offering these at a significantly reduced price compared to pristine pieces. If you don't mind these imperfections, Even so, sapphires of this size are not usually available at this price, so if you want a main-character-worthy sapphire at a low price, please consider this opportunity. Sapphire is the second hardest stone after diamond. Within the mineral corundum, those containing chromium and exhibiting red are called rubies, and all other colors are called sapphires. Rubies and sapphires, while having high hardness, also have fragile structures. To compensate for this, they are often treated with "impregnation," where colorless, transparent lead glass is used to fill the raw stone. This time, we are offering pieces that have undergone this impregnation treatment, giving them a translucent appearance. While opinions on this treatment vary, in the natural stone world, these are actually much higher in price per gram than sapphires that look like pure sodalite. You can enjoy the deep blue color and translucence that most people associate with sapphires. You won't often find this size at this price, so please consider this if you understand the treatment. (Number of beads) 1 (Bead size) Approximately 15mm (Specific imperfections) There are some slightly white areas, but they are less noticeable compared to other pieces. There are also some small chips. Due to the size of these beads, they are sometimes polished aggressively, which can cause scratches around the holes and non-perfectly round shapes.
