Here are a few more photos of this paperweight, I hope that they give a better idea of it’s construction.
Photo No. 1 ; Taken from the side and showing the rims of the two latticinio “discs”, one above and one below.
Here one can see that the spiral latticinio ground which, at a cursory glance, appears to be formed out of two separate “discs”, one seated on top of the other, is in fact formed in one single unit of which both of these “discs” form a part. The very same latticinio threads which form the topmost, smaller “disc” extending downwards to form the larger “disc” beneath it.
Photo No. 2 ; Taken from the side, this also demonstrates the continuity of the latticinio threads.
Photo No. 3 ; Closeup of base of weight.
Photo No. 4 ; Top view, showing construction of central blue/yellow motif, white rod’s “mini-disc” and “star circle”.
The blue/yellow motif, which consists of only one “disc”, is of similar construction to each of the two latticinio “discs” below. The white rod, which forms this motif's central element, flares out to form it’s own tiny “mini-disc”, which can be seen, encapsulated, within the rods of the blue/yellow motif.
What appears to be a circle of minute yellow star canes, surrounding this central white rod, can be seen to be the cross-sections/ends of the blue/yellow rods used to form the central motif, which have been manipulated to create this effect.
