Cost of Pieces of Shell
The cost of ordinary pieces of shell per dozen may be ascertained by reference to the following diagrams:—
Nos. 1 and 2, suitable for small and large ear-rings, 3s. per dozen; No. 3, bracelet size, 4s.; No. 4, larger bracelet or small brooch, 6s.; No. 5, large brooch, 8s.; No. 6, 10s.; No. 7, 15s. to 18s., according to the colour; No. 8, 2s. 6d. to 3s. 6d. each.
The importers of these shells would make up a dozen of various sizes if required. Great care is necessary in selecting pieces suitable for working in order to avoid (1) the mark of a worm left in the early growth of the shell; (2) patches of decayed shell; (3) a tendency to chip, termed “flaking.”
