Exploring the bends of river flows and their karst “imprints” on the Earth’s surface, as well as the architecture of underwater caves and aquatic landscapes, led the designers at ALROSA Diamonds to the imagery of ancient Greek mythology, where Lethe–the river of “forgetting” flowing through the infernal zones of the underworld–was first mentioned. The diamond is a symbol of eternity, existing beyond the bounds of time, and its shifting radiance, forever sealed within precious facets, captivates and mesmerises with its natural beauty.
