In our opinion, the world's best for the species for their definition, crystal size, as well as their color and luster and, in general, very high quality.
Milpillas Mine, Cuitaca, Municipio Santa Cruz, Sonora  Mexico (07-08/2014)

Specimen size: 6.1 × 5.8 × 2.3 cm = 2.40” × 2.28” × 0.91”

Main crystal size: 0.6 × 0.4 cm = 0.24” × 0.16”

ED97AE3: A novelty at Munich 2016. Until now a poorly known mine, the Brochantite forms sprays of finely acicular crystals with an intense silky luster and a very vivid color. They are with darker small Atacamite crystals and are on a Quartz (variety chalcedony) matrix coated by botryoidal Chrysocolla growths. Very aesthetic for the contrast of the Brochantite with the Chrysocolla.
This sample has been photographed and published as a novelty in Munich 2016 in the magazine Le Règne Minéral number 132, page 43, the magazine ‘Mineralogical Record’ on page 148 in the volume 48, number 1 (January-February 2017) and in the magazine ‘Mineral Up’ on page 54 of the 2014/02 edition.
