Dumbledore's hand turned black because he incurred a powerful and fatal curse when he retrieved and destroyed Marvolo Gaunt's Ring, which was one of Lord Voldemort's Horcruxes.
The Cursed Horcrux: Marvolo Gaunt's Ring
Albus Dumbledore, in his relentless pursuit of Lord Voldemort's Horcruxes, located Marvolo Gaunt's Ring, an ancient family heirloom that Voldemort had transformed into a vessel for part of his soul. Recognizing its dark significance, Dumbledore sought to destroy it.
Upon finding the ring, Dumbledore was momentarily tempted by the Resurrection Stone embedded within it – a temptation he succumbed to in a moment of weakness, hoping to see his deceased family members. When he put on the ring, he triggered a powerful and ancient curse designed to protect the Horcrux. For his efforts to retrieve and destroy it with the Sword of Gryffindor, he discovered the ring was deeply cursed. This curse immediately blackened his hand and placed upon him a death sentence, slowly but inevitably killing him.
The Nature of the Curse
The curse inflicted upon Dumbledore was a potent form of dark magic, designed not only to cause physical decay but also to slowly claim the life of anyone who attempted to tamper with the Horcrux. It manifested as a progressive necrotic effect, causing his hand to wither and blacken, signifying the spreading darkness within him.
Severus Snape's Intervention
Despite its devastating power, the curse was not immediately fatal thanks to the timely intervention of Severus Snape. A master of Potions and Dark Arts, Snape was able to contain the curse to Dumbledore's hand, preventing its immediate spread throughout his body. However, even Snape's formidable skills could not lift the curse entirely. He could only slow its progression, granting Dumbledore a limited amount of time to live, ensuring his death within approximately a year.

The Broader Implications

The blackening of his hand served as a constant, stark reminder of his impending demise and the immense sacrifice required to defeat the Dark Lord.
