These are 15mm+ blue sapphire beads, which are not usually sold individually. However, with this size, there are imperfections such as difficulty in successful 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, Even so, sapphires of this size are not available at low prices, 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 are called rubies, and all other colors are called sapphires. Rubies and sapphires have high hardness but also have fragile structures. To basically reinforce their strength, they undergo "impregnation treatment," which involves filling the raw stone with colorless, transparent lead glass. This time, we are offering specimens that have undergone such impregnation treatment, giving them a translucent appearance. While opinions on the treatment are divided, in the natural stone world, these are actually far more expensive per gram than sapphires that look like pure sodalite. And 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 of these beads, they are polished with some force, and there may be scratches around the holes and areas that are not perfectly round. Please understand this before purchasing.
