This is one of my favorite colors of Loetz glass. Rubin (Ruby) matt iris is a deep red color that presents as purple or violet because of the iridescence, but the glass is actually a rich red that you have to hold in hand to appreciate. The large squat form has a three sided rim, with three offset indents to the body of the vase. The production number is II-658 (See Neuwirth, Loetz 1900). Vase is in excellent used condition, with no chips, cracks, or repairs. The spots on the base are museum putty residue that can be removed. Dimensions are: Height 6", Width about 7", and weight before packaging is 1 lb., 14 oz.
