First of all, the color of chalcedony is one of the important factors that determine its value. High-quality red chalcedony is usually bright red in color, uniform in tone, without impurities or uneven in color distribution. This color of chalcedony is often more valuable.
Secondly, the purity of carnelian will also affect its value. Clarity refers to the number and visibility of inclusions or cracks in a gem. High-purity carnelian is usually more precious because they are relatively rare.
Finally, the size and cutting of carnelian will also affect its value. Red chalcedony with large volume, meticulous cutting and exquisite cutting technology is often more expensive.
In a word, the Millennium carnelian beads in West Asia are valuable jewels, and their value depends on factors such as color, purity, size and cutting. If you have a carnelian bead, and its quality meets the above requirements, then it is likely to have high value. But the specific value needs to be evaluated by a professional jewelry appraiser.
