This is a stunning piece of glass. Exceptional glow of green, pink, gold, and purple iridescences.This beautiful blown glass vase has a hard ribbed exterior, ruffled tulip shape mouth, and encased mix of green and pink glass. Pontil mark on base and one air bubble on the inside of vase. No chips, cracks or repairs. It stands a good 6 5/8 inches tall and about 3 ¾ diamiter. I could not find a signature. Loetz or Kralik? A beautiful vase for any glass collection.
