Six leaves, all judged by eye
On this page12
The group has six leaves and they share something no other group here does
Cabochon storage, crystal point, loose gemstone, pearl loose, seed bead storage and tumbled bead. Every one of them is identified, sorted and valued by appearance.
Which is not true of most shelves in this library
A fastener is identified by a thread size. A fuse by a printed rating. A bit by a stamped diameter. Those are read, not looked at. Here there is nothing printed and appearance is the whole record.
So a container that hides the contents removes the identification
A jar of unidentified cabochons has to be opened and emptied to be sorted. A clear jar is read without being opened, which on this shelf is a functional difference rather than a preference.
Seed beads are the smallest and the most numerous
A size 11 seed bead is under two millimeters, and a working stock is thousands of them in dozens of colors. Seventeen of the 184 containers hold 15 milliliters or less, which is the band that suits a single color.
And they are the leaf where the closure matters most
Beads find every gap. A lid that is resting rather than turned down will spill a jar of them, and 180 of the 265 closures here are plain continuous thread lids that seat properly when turned.
A crystal point is the opposite shape problem
Long, tapered, with a tip that chips. It wants height and a soft interior, and the shelf runs to 6.75 inches with a median of 2.38, so the tall end is thin but present.
Cabochons are flat and want a floor they can lie on
A domed stone with a flat back stacks badly and scratches well. Spread flat in a shallow container it can be seen and picked; piled in a deep one it cannot.
Loose gemstones are the leaf where the container is the smallest part of the job
Individual stones are usually kept in papers or padded boxes rather than loose in a jar, and what goes in with them matters more than the jar. That is outside what this catalog records.
Pearls are the one leaf with a material sensitivity
Nacre is a carbonate and it is soft, so pearls mark against each other and against a hard wall. Which argues for separation and padding rather than for any particular container.
And tumbled beads are the easy case
Hard, rounded, indifferent. They need a container that closes and a label, which is most of this shelf.
None of the six is reached by the guides above
Part 23 addresses how a seller may describe a stone or a pearl. It does not govern a container and it does not reach a row on this shelf, and nothing on these pages determines the identity or treatment of anything.
