Glass ornaments

Set of fourteen matching ornaments, all made in same or very similar molds.
Semi-translucent cobalt blue (12 examples) or light blue green (2 examples).
Vertical rectangular panel; uneven flat back; straight sides and bottom edge; a large hole running horizontally through reel at top, four holes in recessed circle near bottom, and tiny hole in spikes along left edge on some examples.
Molded decoration on front: a series of three reels, each with a truncated pyramidal spike projecting at left; three pairs of wavy lines in relief run vertically down reels, with other finer lines between spikes on left; below, square, flanked above and below by a horizontal row of dots, containing a plain recessed circle pierced holes.
Two ornaments are intact, two are broken but complete, and the rest are fragmentary; dulling, pitting, and thick creamy brown weathering.

The motif, evidently depicting locks of hair, suggests that these elements belonged to a diadem. The perforations at the top of each element would have allowed them to be strung together.
