For your consideration is a vintage large art glass swirl, silver mica flakes dichroic, magnum paperweight.  There is silver mica flakes in the lower center of the paperweight.  Around the silver mica is swirls of black, blue, white and light brown.  The color combination in the piece is catching and gorgeous reminding me of a starry night.  Measures 3" tall and 3 1/4" in diameter. Etched signed on the bottom.   This is from a local estate that loved quality art glass.
