Look at the mishna Sotah 9:12 that the use of the Shamir stopped after the destruction of the temple, the second beis hamikdash. See the Melaches Shliome there. It was created erev shabbos ben hashmoshas used to cut precious stones in the beis hamikdash. It was called Shamir to protect ir from cutting things accidentally.
