Man-Made Diamonds

Startup Diamond Foundry Makes Their Own Ethical Diamonds and Bespoke Jewelry

The last decade has seen an increasing social awareness among consumers, including the jewelry industry, which has led to increased demand for ethical diamonds. The rising popularity of ethically sourced gems is likely due at least in part to Leonardo DiCaprio's 2006 film Blood Diamond. The actor is also an investor in Diamond Foundry, which makes, not mines, sustainable diamonds.

Located in California, Diamond Foundry uses 8000 degree Fahrenheit plasma reactors to make their own ethical diamonds, rather than resorting to mining them in the African continent. The man-made gems are also indistinguishable from those you might find from well-known brands like Tiffany & Co.

Offering bespoke engagement rings among other jewelry, the startup speaks not just to the consumer's desire for transparency, but to customized design as well.
