The First Hokage's necklace (初代火影の首飾り, Shodai Hokage no Kubikazari) was the necklace worn by Naruto Uzumaki. It was made from a special "Crystal Gem" (結晶石, Kesshōseki) and was once worn by the First Hokage. If it was to be sold, three mountains containing gold mines could be bought with the profits.
The First Hokage's granddaughter, Tsunade, inherited it several decades before the start of the series. She in turn gave it to both her younger brother, Nawaki, and her lover, Dan, in the hopes that it would help them achieve their dreams of becoming Hokage. Both died soon after receiving the necklace during the Second Shinobi World War, returning the necklace to Tsunade's possession and leading others to believe the necklace was cursed. Believing this, Tsunade kept the necklace for herself for the next few years and lost faith in those who dream of becoming Hokage.
In Part I of the series, Tsunade met Naruto Uzumaki. Not only did he dream of becoming Hokage but he also bore some resemblance to both Nawaki and Dan. Deciding to tempt fate one more time, Tsunade made a bet with Naruto: if he could master the Rasengan in a week, therefore proving himself worthy of the position of Hokage, she would give him her necklace. He agreed and was able to accomplish the task, prompting Tsunade to put faith in the title of Hokage and the necklace one more time.
In Part II, when Naruto lost control upon advancing to his six-tailed form, the necklace activated in an attempt to stop the transformation. However, due to the overpowering influence of the Nine-Tailed Demon Fox, it destroyed the necklace. Yamato claimed that without the necklace, it would be impossible for him to help Naruto suppress the Nine-Tails' chakra any longer, were it to resurface. However, this may not be completely true, as Yamato once again tried to suppress the transformation while they were in the Falls of Truth, without the necklace's assistance.
A power unique to Hashirama was the ability to control jinchūriki and the tailed beasts. This ability was enhanced by the necklace, which responded to his chakra, allowing him to control the chakra of the tailed beasts. It is said that Hashirama's Hokage-Style Sixty-Year-Old Technique — Kakuan Entering Society with Bliss-Bringing Hands responds to this necklace to suppress the Nine-Tails' chakra when it influences Naruto. Yamato at some point in time added a seal to the necklace that would activate when Naruto called upon too much of the Nine-Tails' chakra, attempting to restrain him, and alerting Yamato to what was happening.
