Recently, the Natural Diamond Council encouraged suppliers, retailers, and consumers to use the day to celebrate natural diamonds globally. The date was chosen because April’s birthstone is diamond, and the number eight represents infinity.
Participants were encouraged to use social media on the day to post content acknowledging the significance of natural diamonds. Contributors posted stories using the hashtags #WorldDiamondDay and #NaturalDiamonds.
The initiative received widespread support, with groups and organisations including the Gemological Institute of America (GIA), World Jewellery Confederation (CIBJO), Antwerp World Diamond Centre (AWDC), and India's Gem and Jewellery Promotion Council (GJEPC) taking part.
“The inaugural moment was designed to bring the industry together around a single, shared voice. With that foundation now in place, the Natural Diamond Council is positioned to expand World Diamond Day into a broader consumer-facing movement in the years ahead,” a statement reads.
“World Diamond Day was conceived not as a campaign, but as an annual movement rooted in real stories, shared openly across platforms, and driven by collective participation.
“In a world where so much feels fast and easily replicated, natural diamonds remain a constant. They are symbols of something deeper: time, memory, and human connection. Formed over billions of years, each one carries a story. On World Diamond Day, those stories were shared across the world.”
The statement noted that more than 50 retailers across markets worldwide participated in the campaign, including Signet, Ben Bridge, and Chow Tai Fook.
