Calcite with Duftite

This piece is from my personal collection. I have considered trimming it about 100 times, but I am stopped by the multitude of areas of interest throughout. I bought it for the fine array of calcites. accented by a fine coating of duftite on the matrix. Closer inspection finds rhombs of calcite included with the duftite. On the back is a colorful coating of duftite over small quartz crystals.
