Pair Victorian cased glass vases with raised enamel & applied decoration - Early Loetz

Okay, so I often say that I'm trying not to get any more "big" glass...but, sometimes you just have to break your own rules when something this good comes along.
I was watching these on eBay AU, & they ended without selling, then got relisted at a lower price, so I thought, why not?
I have a feeling they are Early Loetz, & the quality is outstanding in every aspect. Condition is also perfect.
The vases are made from three layers of cased glass - a "spreading" orange/pink/salmon over a clear middle layer, with a milky opalescent interior. They measure 27 cm tall, 7.5 cm across the top rim, & 10.5 cm across the applied footed base.
There is an applied rustic branch in clear glass which cleverly complements the raised enamel decoration of branches with oak leaves. The vases have a fine ribbed pattern, & are cylindrical in form, tapering towards the base, where they are joined to a clear rustic cupped form which attaches to the base. Base has a slightly irregular pleated effect, with traces of gilding visible around the edge.
I was aware of the height of the vases, but in person they have quite a girth around, making them an imposing pair. After a quick reshuffle, I managed to find an appropriate spot for them - flanking an equally large cased satin glass basket.
