I hand cut this one of a kind focal bead. Measurements in the title. A freeform shape with a polished finish and sparkling golden needles. Astrophyllite gets its name, from the Greek words astron meaning "star" and phyllon meaning "leaf". Among the mionerals it is associated with that may be included in the matrix are feldspar, mica, titanite, zircon, nepheline, and aegirine. A beautiful and unusual stone. The material I cut this from is genuine astrophyllite in matrix from Russia. I also have cabochons in the material in my store. CHAIN NOT INCLUDED.
