Description: The color and luster are amazing. Although not on matrix, due to its transparency, intensity of color, and good crystal definition, it deserves to be considered an important piece. From the Jordi Fabre collection, it was bought from the historic Andrés Puente in 1979. Andrés was the one who had the best Áliva pieces at that time. The specimen has been photographed and published in the magazine Paragénesis, number 01/2022, page 74
