This is a large 9.5mm 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-shaped (phantom) effect between the areas with and without inclusions. Furthermore, this piece also exhibits a white phantom. In other words, the following sequence of events can be observed: ① Crystal growth ② Growth temporarily stops, and a white haze develops on the surface ③ Crystal growth resumes (white phantom is trapped) ④ Metal components that become Super Seven are supplied, forming a red phantom ⑤ Crystal growth resumes The fact that both are visible makes this a rare find, so please consider it. (Number of beads) 1 (Bead size) Approximately 9.5mm (Shipping method) Will be sent via Mercari delivery. It will be packed with air cell mat and shipped promptly.
