Here we have a beautiful Austrian green glass vase from the late 19th century Art Nouveau period.  Has a stunning oily, iridescent finish.  Made by Loetz, part of their "Creta Glatt" pattern range.  Items from this range are shown on the Kralik website [click here], and this particular shape is shown at the bottom of the linked page.

Measures approx 3.5 inches tall by 3.5 inches in diameter at widest point.

Excellent condition, no chips or cracks, just a small manufacturing flaw to the inside neck of the vase, shown in final picture.
