Keilim11: 9
[ט] נֶזֶם שֶׁהוּא עָשׂוּי כִּקְדֵרָה מִלְּמַטָּן וְכַעֲדָשָׁה מִלְמַעְלָן, וְנִפְרַק, כִּקְדֵרָה — טָמֵא מִשּׁוּם כְּלִי בֵית קִבּוּל, וְכַעֲדָשָׁה — טָמֵא בִּפְנֵי עַצְמוֹ. צִנּוֹרָא — טְהוֹרָה. הֶעָשׂוּי כְּמִין אֶשְׁכֹּל, וְנִפְרַק — טָהוֹר.
[Regarding] an earring that is shaped like a pot at its lower end and like a lentil at its top, and [it] came apart, [the section] resembling a pot is tamei because [it is a] utensil with a receptacle, and the lentil-shaped [section] is tamei by itself. [However,] the hook is tahor. [An earring] that was made like a cluster [of grapes], and it came apart, is tahor.
