Recently I bought 2 vases (1st photo) Loetz in decor Diaspora on Diana Ciselé. The vase in the 2nd photo I have had for some time - the color of the glass is a bit darker, but the yellow-green spots are the same. Compared to the classic Diaspora decor, these 3 vases are otherwise iridized (see photo 3). I would describe it as a subtly structured iridescence. (something between "diaspora creta silberiris" and creta diaspora). The 4th photo shows the difference between creta diaspora and "diaspora on diana ciselé". Maybe this decor has a specific name that I don't know yet.
It is a similar difference as the Wellenoptisch and Oceanik.
