Although the designers at Loetz were the early innovators, they were not the only firm to make glass resembling semi-precious stones. Here are only a few varieties of marmoriertes glass:
Photo 1, L to R (all Loetz): Malachit, Onyx, Carneol, Green Onyx
Photo 2: Loetz Carneol double handled console bowl, ca. 1889
Photo 3: Loetz Carneol enameled platter, ca. 1900
Photo 4, L to R - Harrach ca. 1900, except for the fourth piece from the left, which is probably Josephine glassworks, ca. 1921. The pink and blue one is generally accepted as being Loetz.
The next one I would like to find is quite rare, but I'm holding out hope: Loetz Lapis!
