About Ada Diamonds

Ada Diamonds was founded in 2015 by two partners seeking a gorgeous, environmentally friendly engagement ring to symbolize their love. After a frustrating experience building a custom engagement ring with lab diamonds, they knew they weren't alone, and subsequently founded Ada to help others build beautiful, meaningful diamond jewelry.

Today, Ada Diamonds operates a socially-progressive company working to build a better and brighter future for all. Read about our philanthropic efforts and quest to challenge the status quo of the diamond industry. Learn about our values, genesis, and mission statement.
