These vials contain common semi-precious stones and pearls that are used in stumpwork. Seed pearls are often found strung as necklaces for women. A cut one inch length of seed pearls is included in the seed pearl vial as well as any single pearls that fell off the length. If you intend to use the pearls as a necklace, you might carefully lay the length in place and couch it down and then hide the ends, removing any excess pearls. Seed pearls are notoriously hard to fit a needle in, therefore the string they arrived on was kept intact. If you need to restring, heavily wax a thread and try to feed it through the hole without a needle.
Grottos on stumpwork often had semi-precious stones, shells and coral attached to the embroidered rocks. The stones could be as large as 3/4" in width on some large stumpwork pictures I have seen. The vial of semi-precious stones contains one of each of the following eleven beads which range in size, none larger than 4mm in diameter. The sampling is intended to save the student from purchasing large quantities of each to get a sampling for their grotto.
