Haida glass vase, possibly Carl Goldberg, ca. 1930

I have been in love with this piece for months, watching it come and go on eBay while being distracted by other things, and a fortunate series of events made the timing right to finally bring it home.

Clear glass thick-walled body is acid cut back in a diamond motif with an iridescent metal oxide enamel reduction (of the kind employed famously by Carl Goldberg) and bordered with dark blue enamels. The rim is flat cut and polished, and the bottom is also flat and polished. It is marked "Made in Czechoslovakia" within a rectangle (but in a different font than the Loetz mark from the same period). It is about 8.5" tall and in excellent condition.
