Amethyst Intaglio Spills or Cigarette Holders

Made in England circa 1920 - 30. Designed for holding spills [long, thin slips of wood for lighting pipes, cigars etc.] Others have suggested they held cigarettes - 10 each or perhaps they are toothpick holders? Someone who follows this site might know their real function. The colour is a brilliant purple, especially when held against a light source. The solid crystal bases are lens cut on the bottom circumference. Three flower heads are intaglio cut on each side for both holders as well as a smaller flower on each edge . I've seen another example in cranberry glass. They are commercial items which are both unusual and attractive - a relic of a bygone era. Dimensions: 7.5 cms high and 10 cms [4 inches] across the diameter of the crystal base. The top opening is the width of a cigarette. Very good weight. Each has a highly polished pontil.
