A Set of Seven Glass Wine Stems with Guilloché Etching - A set of seven glass wine stems featuring a slightly flared U-shaped bowl, a straight cylindrical stem, and a flat circular foot. Each bowl is decorated with a delicate machine-engraved or acid-etched guilloché band composed of interlocking and overlapping circles forming a continuous mesh-like pattern around the circumference. The glass is clear with a polished finish and thin rims. The construction involves a drawn or joined stem to the bowl and foot. No maker's marks, signatures, or labels are visible on any of the pieces.
