Description: In 2019, when testing new materials for our jewelry production, we came across this thin dendritic layer within a rock. When looking at the rock and other samples from the area we recognized that we had something extraordinary in front of us: A constant pattern resembling a horizon with trees and bushes in front of white snow-capped mountains under a bloodred sunset sky. We named it “Red River Sunset”® in honor of the unique Red River near Cusco, Peru. After laboratory testing this material we now know that Red River Sunset® is a bicolored calcite-dominant carbonate. The red layer is more iron-rich, although the highest percentage found during testing is only 0.89 %. However, iron is a powerful coloring agent. According to testing this material is most likely travertine. Travertine is a form of terrestrial limestone deposited around mineral springs, especially hot springs.
