Charities

At Diamond Design Co. we are committed to giving back to our communities and others in need. Throughout the year we contribute a portion of our sales to various charities. We choose these charities based on our family, friends and causes close to our heart, especially for children. We share this with you so you can know that you are helping us to contribute.

Jewelers for Children As the industry’s charity, Jewelers for Children (JFC) is generously supported by those who create and sell fine jewelry and watches. Manufacturers, retail jewelers, trade associations, watch companies and those who provide professional services to the jewelry industry unite on behalf of children.
San Francisco CASA

Over two thousand of San Francisco's children are victims of abuse and neglect and are living in foster care.

Adrift in an overburdened public social services system, these children urgently need safe and permanent homes, educational and healthcare services, and the support of a responsible and caring adult.

The SFCASA volunteer's commitment is intense, and his or her impact on the child's life is significant. SFCASA is the only agency operating in San Francisco providing court appointed volunteer advocacy and mentorship exclusively to this group of highly disadvantaged young people.

Susan G. Komen Foundation For more than 20 years, the Susan G.

Working through a network of U.S. and international Affiliates and events like the Komen Race for the Cure®, the Komen Foundation is fighting to eradicate breast cancer as a life-threatening disease by funding research grants and supporting education, screening and treatment projects in communities around the world.
American Red Cross

From floods and tornadoes to wildfires and residential fires…from hurricanes that devastated entire communities throughout the southeast U.S. to a catastrophic earthquake and tsunami that roared through southern Asia and eastern Africa countries destroying lives, families, homes and livelihoods.

Because of the public’s generous support the American Red Cross has been able to respond immediately whether the need was around the corner or halfway around the world.
