The glass cabinets of the drawing room of this strange old house contained many items that seemed reluctant to leave their shelves. It is not known if these items were actually filled with Dark Magic or not, but some certainly seemed intent on causing harm. Other sinister items and objects were found throughout the house.
an ornate crystal bottle with a large opal set into the stopper, full of what looked like blood
boxes, made of tarnished silver and inscribed with languages Harry did not understand
dusty box containing an Order of Merlin First Class given to Sirius' grandfather for Services to the Ministry. Kreacher stole this back, but it was then stolen from him by Mundungus Fletcher after Sirius' death .
china with the Black crest and motto (evidently the same motto as that on the genealogical tapestry, which means "Always Pure" in French)
family photos in silver frames
a grandfather clock that shot heavy bolts at passers-by
a spidery instrument, rather like a many-legged tweezers, which scurried away and tried to puncture Harry's skin
a heavy locket that no one could open
a music box that played a faintly sinister, tinkling tune when wound that nearly knocked everyone out Kreacher stole this back, but it was then stolen from him by Mundungus Fletcher after Sirius' death
a ring, large and golden, bearing the Black family crest
an ancient set of purple robes that tried to strangle Ron when they were removed from their wardrobe
several ancient seals
