In 2008, Bündchen auctioned a collection of diamonds to benefit the Diamond Empowerment Fund, a nonprofit organization to education initiatives in countries where diamonds are a natural resource. The collection featured the Ponahalo Diamonds which were valued at $2 million to $4 million, a 6-carat diamond ring worth $120,000–$150,000 and a 3.35-carat Sabbadini diamond ring worth $15,000–$20,000. In 2010, she donated $1.5 million to the Red Cross to aid the relief effort in Haiti after seeing the devastation done by the earthquake. The donation put Bündchen tied for 14th on The Giving Back Fund's list of 30 celebrities who made the largest donations to charity in 2011. In 2010, together with former president Bill Clinton, Bündchen joined the event that partnered Pantene and the Children's Safe Drinking Water Program to provide clean water to people in need. Bündchen and Indonesian singer-songwriter Anggun announced the kick-off of the Healthy Hair for Healthy Water program at P&G's reception that was held in conjunction with the 2010 Clinton Global Initiative in New York City. Bündchen also attended the Brazil Foundation's 8th Annual Gala to raise funds for fighting challenges faced by poor communities in Brazil. Bündchen created an exclusive design for SIGG water bottles, with proceeds going to WaterCan NGO, a humanitarian organization in Canada that provides the poorest people in the world access to clean water, toilets, and information on hygiene. In 2020, Bündchen formed the Luz Alliance fund in partnership with the Brazil Foundation with a donation of 1,000,000 reals. The fund supports the purchase of hygiene kits, food, and financial assistance to families in Brazil through eight different charitable organizations and emergency-response efforts to offset the impact of the coronavirus pandemic. Bündchen, along with her husband Brady, partnered with Wheels Up to donate 10 million meals to Feeding America for their "Meals Up" initiative and helped fund thousands of meals for Feeding Tampa Bay and The Greater Boston Food Bank to alleviate food insecurity. Bündchen also partnered with the "All in Challenge" by donated an experience with her at a photo shoot in New York, with all proceeds going to Feeding America, Meals on Wheels, World Central Kitchen and No Kid Hungry. In 2004, after visiting an Indian tribe at the Xingu region in Brazil and seeing firsthand the problems those communities were facing due to water pollution and deforestation Bündchen decided she had to do something to help bring attention to social and environmental issues.
