These are 15mm+ blue sapphire beads, which are not usually sold individually. However, due to their size, there may be imperfections such as difficulty with impregnation, chips, and the presence of white areas. To convey how difficult it is to find large, near-perfect specimens, we are offering these at a significantly reduced price compared to beautiful specimens. If you don't mind these imperfections, However, sapphires of this size are not usually available at this price, so if you want a main-character-level 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 color are called rubies, and all other colors are called sapphires. Rubies and sapphires have high hardness but 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 specimens 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.

Due to the size, these may have scratches around the holes or may not be perfectly round due to the forced polishing. Please understand this before purchasing.
