This is a large 11mm bead of Red Super Seven, which contains the iron hydroxide mineral, lepidocrocite. In addition, the inclusions in this bead are concentrated up to a certain point in the crystal's growth, creating a mountain-like (phantom) shape with areas of inclusion and areas without. Furthermore, this individual piece also shows a white phantom. In other words: ① Crystal growth ② Growth temporarily stops, and a white haze develops on the surface ③ Crystal grows again (white mountain is trapped) ④ Metal components that become Super Seven are supplied, and a red mountain is formed ⑤ Crystal grows again This sequence of events can be understood. It's rare to find both, so please consider it. (Number of beads) 1 (Bead size) Approximately 11.5mm (Shipping method) Will be sent via Mercari delivery. It will be packed with air cell mat and shipped quickly. If you have any questions, please leave a comment and I will answer, but I will reply late at night on weekdays due to work.
