The first of the two bubbles travels far enough to qualify as a commute! Two Smoky Amethyst Phantoms with a distinctly clear band between them align with the interior space the bubble travels across. A secondary bubble, mobile but with less range of movement. The matrix is covered in smaller crystals of Quartz, creating an excellent presentation. Brandberg, Namibia. 3" x 2" x 2", 8.9 oz. (The marker rubs off with alcohol, fear not)
