Fluorescent light (daylight)

SV21800NXF

An important piece due not only to the minerals that form it, but by the very association of both species on the same piece, which is not common. Metallic grey Nagyagite crystals with preferentially oriented growths, are implanted in a slightly pink crystalline Quartz matrix and accompanied by darker lanceolate crystals of Sylvanite.
A historical specimen, obtained at the end of the 19th century, from a classic mining district in Romania that has deposits in which gold, silver and tellurium are exploited and that is the type locality (TL) for Nagyágite. From the collection of Ignacio Gaspar Sintes whose handwritten record we will send to the purchaser.

SV2680TGA

Novelty on the market in 2022.
Arborescent Silver, very aerial and aesthetic, with very marked spinel-law twinning. It is on matrix, surrounding a rocky core decorated by Calcite crystals that differentiate it from the classic Hongda silvers.
