Amethyst Beta Quartz: crystal cluster - Elestial Sceptre

This rare Amethyst Beta Quartz crystal cluster has white core, which protrudes to form a self-healed elestiated stalk, embedded with limonite(?) crystals. The main crystal body is semi-opaque, but clearly shows inner horizontal layers of purple amethyst and smoky quartz - 3 of the faces showing elestiation. Adjacent to the stalk 2 are small but perfect deep amethyst Beta crystals, with paler phantoms, making this an intriguing cluster.
