Sapphire is the second hardest stone after diamond. Among the mineral corundum, the red variety containing chromium is called ruby, and other colors are called sapphire. Purple color is originally a high-end choice, but we offer it at a lower price because it includes some uneven coloring and more subdued shades. The rough stones of ruby and sapphire are mostly more understated in color than we imagine, and their structure is often fragile. Of course, gem-quality crystals are also produced, albeit in small quantities, but these are invariably processed into jewelry loose stones, so they are rarely polished into round bead beads like these. Therefore, the beads widely available are either those with a modest color that have been processed as they are, or bead bracelets that have undergone "impregnation treatment," where lead glass is filled into the rough stone to significantly enhance the color by human hands. Unlike those, these beads are made from rough stones with a dense structure and good color. They have undergone only minimal impregnation treatment to allow you to enjoy them as power stones for a long time, and are processed in the same way as the excavated rough stones. This is a minor treatment compared to the heavy impregnation mentioned above, and can be considered a form of enhancement. Please consider it.
