Gorgeous natural Chalcedony from Indonesia we had cut exclusively for usin small 3.8 to 4mm rondelle beads! Gorgeous 100% natural color.
The color varies from rich dark purple to gentle lavender and violet. This is the result of a complex relationship between ferric iron or other transition metal content (possibly aluminum and manganese) and a play of light absorption on the atomic bonds within the stone.
Please note: This is not a finished necklace, these beads are temporarily strung.
