The precious stone traditionally given on a 60th wedding anniversary is a diamond. Celebrating a 60th anniversary, also known as a diamond anniversary, symbolizes enduring love, commitment, and the strength of a long-lasting marriage. Diamonds, one of the hardest natural substances on Earth, represent durability and resilience, which parallels the journey of a couple who has been together for six decades. Though traditionally the gift could range from diamond jewelry to more creative interpretations, the essence remains a celebration of lasting love valued over the years.
