"The broadcollar was the most common type of Old Kingdom jewelry. At Giza alone, George Reisner found nineteen such collars in tombs of both men and women. In addition, brightly painted broadcollars are represented on statuary and reliefs of deities, royalty, and wealthy private individuals from the Old Kingdom through Roman times. Although jewelry was often made for funerary purposes only, in this case the presence of the counterpoise that served to redistribute the weight of the collar and to ensure that it hung properly suggests that this example was worn in life as well."

I didn't capture the info about the tyet fragments in the top photo. I wasn't able to find them on the museum website, but a few fragments looked similar. However, gizapyramids.org has the info:

Fragments of twelve ivory inlays in form of Isis knots from G 7000 SE 77: 29-2-22 (= MFA 29.2217.1-12)

I see now why all my search terms failed. They now think these are 'bone', rather than 'ivory'. And the museum website is calling them "girdle-knots", rather than "Isis knots" or "tyets". While the original guess was use as furniture ornaments, they now have expanded that to they "would have decorated the side of a chair."
