Constantin 18K Yellow Gold Lapis Lazuli Earrings

The over-80-year-old Brazilian jewelry house—one of the country’s most prominent—was founded by the man who discovered Brazil’s first emerald mine. Cast in recycled 18k yellow gold and exquisite locally-sourced stones, the pieces here nod to the lushness and hues of the Amazon rainforest. For every piece sold, Sauer will plant trees in the Amazon in partnership with IDESAM.
