Magic Headgear, Circlet

Enchanted items with some visual characteristics of "jewelry" that are meant to be worn on the upper skull of their user. They can be covered up by nonmagical weather gear for the head such as a hat, a hood, a turban, or a headscarf, but are not compatible with also wearing a crown, a coronet, a laurel, a diadem, a tiara, a corolla, a helm or helmet, a phylactery, large / bulky hair pins or combs or brooches, a jeweled hairband, or other items meant to be affixed to the forehead and upper head region, and usually not with a mask either depending upon construction.
They are probably not compatible with goggles or eyeglasses, either.
Veils, ear and facial piercings, wigs, and small hair clasps should be fine so long as (1) they do not interfere with the placement of the coronet against the user; (2) they are not enchanted items.
Wearing two or more enchanted items in the head area (with the exception of earrings or certain facial piercings, in which case: consult with GM) will cause all enchanted items to cease to benefit the wearer, and may lead to spontaneous curses developing due to the interference. The only exception to this rule would be a specially-designed Legendary Set which are meant to be worn all at once, and such a thing has not been a realistic possibility in so long that it may have only ever existed in fiction.
