Swiss Blue Topaz Mirror Ball Cut Bracelet Natural Stone Power Stone ★ Bead size: Approximately 6.6mm to 6.9mm ★ Inner diameter: Approximately 16cm ※ Please refer to the grid pattern photo for the size of the stones. The grid background photo is a 1cm graph paper pattern. This is a cool Swiss Blue Topaz with a clear, light blue color. It has a mirror ball cut, which reflects light and sparkles. The color is heat-treated. There are some internal cracks and imperfections in the cut, but they are not very noticeable due to the small size and sparkling cut. Similar-looking natural stones include aquamarine and blue crack quartz, but topaz has a higher refractive index and is a heavier mineral than other similar minerals. The sparkle that reflects light, unique to topaz, and the substantial weight give it a luxurious feel. It can be worn as is, or it would look great as a focal point in a design bracelet or combined with a dzi bead. It can also be used as a handmade material for pendant tops, keychains, straps, earrings, etc. There may be natural stone characteristics such as stone marks, original color unevenness, chips, dents, flat areas, and rough spots from polishing. The through-hole may not be clean. I have kept it wrapped in cushioning material since I bought it, so I only ask that those who understand that the dirt and scratches are not from later on please purchase. Please understand that the color may appear different depending on the monitor. ※ Please check the condition in the photos, as the item in the photos will be sent. #bluetopaz #bluetopa #topaz #skybluebluetopaz #swissbluetopaz #londonbluetopaz
