Hufflepuff Cup Necklace

The cup was a creation of Helga Hufflepuff, the celebrated Founder of Hufflepuff House. It was described as a shining golden cup with two finely wrought handles on either side and a badger engraved on its surface.The cup was said to possess many magical powers, though the exact nature of those powers is not known. Hufflepuff was brilliant with food-related charms and with house-elves, so the cup may have been the very first dining utensil at Hogwarts to assist in the magical transportation of food from the House-Elf Kitchens. The cup remained with Hufflepuff until the time of her death.

The cup was passed down through the Hufflepuff family, and through the centuries made its way to Hepzibah Smith, a descendant who kept the cup as a priceless heirloom. In 1946, Smith showed the cup to Tom Marvolo Riddle, who was at that time employed at Borgin and Burkes. She dazzled Riddle with the cup and fondly stated she could never part with it. Along with the cup, Smith possessed Salazar Slytherin's locket. She kept them well hidden even from her family members.

Smith was found dead two days later. Her elderly house-elf, Hokey, recalled mistakenly putting poison in Smith's cocoa, however, Riddle had embedded a false memory in Hokey as he himself had murdered Smith for the artefacts. Riddle fled with the cup and the locket. Smith's family realised the cup and the locket were missing shortly after her death, but by that time Riddle had resigned his post at Borgin and Burkes. Riddle was neither seen nor heard of for a decade.

Riddle, or Lord Voldemort as he called himself at that point, transformed the cup into his fourth Horcrux, using Smith's murder as the tool.
