I am also listing another carnelian, but this one is a bit more expensive due to its high transparency. Carnelian is a natural stone characterized by its vibrant red color and is also known as the birthstone for July. It is a type of quartz, and those with stripes are also called red agate. However, those with a relatively uniform color, as shown in the image, are often sold as carnelian. This stone is popular as a power stone that gives the wearer strength, courage, and the ability to take action, leading to goal achievement and success. Inner diameter: 15cm Approximately 10mm beads
