What is the difference between places of adornment (mawāḍiʿ al-zīnah) and the adornment itself (ʿayn al-zīnah) for a woman?

The term "places of adornment" (مواضع الزينة) in the discourse of the jurists refers to the parts of the body where a woman places her adornments, such as jewelry and henna, as distinct from the adornment itself, which is the object used for beautification. The jurists deduced from the noble verse: "And let them not expose their adornment except to their husbands" [An-Nur: 31] that what is meant by "places of adornment" are the parts of the body that maharim (unmarriageable kin) are permitted to look at, such as the face, head, chest, shins, and upper arms. This also includes the forearm, ear, neck, and foot, because these are places of adornment, unlike the back, stomach, and thigh. Thus, the verse indicates the permissibility of exposing the places of adornment, because exposing the adornment itself is inconceivable without exposing its location.
