A goblin-wrought sword that Dumbledore used to destroy the ring Horcrux — it absorbs what strengthens it.
Dumbledore used the Sword to destroy the Horcrux in Marvolo's ring. The Sword is goblin-made and absorbs anything that makes it stronger — it took in basilisk venom in the Chamber of Secrets and can now destroy Horcruxes.
A ruby-encrusted silver sword with the name 'Godric Gryffindor' engraved on the blade.
