SV2140NAA: Calomel with Eglestonite and Mercury
A novelty for Spanish mineralogy (see: La extraordinaria paragénesis de minerales de mercurio de Usagre) Crystals of Calomel with an adamantine luster, on matrix, one of them clearly dominant and easily visible, deposited in a cavity full of translucent honey-colored Eglestonite crystals, a mineral, product of the alteration of other mercury minerals, an element that is also present on the specimen as drops that are held thanks to its high surface tension. Both species of mercury halides have been analyzed and we will send copy of the analysis to the buyer. These minerals are photosensitive, blackening easily when exposed to sunlight and even under the light of a lamp, so we recommend keeping them out of the reach of light.

SV2170NAD: Calomel with Eglestonite and Mercury
A novelty for Spanish mineralogy (see: La extraordinaria paragénesis de minerales de mercurio de Usagre) Crystals of Calomel with an adamantine luster, one of them clearly dominant and easily visible, deposited in a cavity full of translucent honey-colored Eglestonite crystals, a mineral, product of alteration of other mercury minerals, an element that is also present in the specimen as drops of native Mercury that hold together thanks to their high surface tension. Both of the mercury halide species have been analyzed and we will send a copy of the analysis to the buyer. These minerals are photosensitive, blackening easily when exposed to sunlight and even under the light of a lamp, so we recommend keeping them out of the reach of light.

NFG88AQ0: Calomel with Eglestonite, Mercury and Cinnabar
A novelty for Spanish mineralogy (see: La extraordinaria paragénesis de minerales de mercurio de Usagre) Crystals of Calomel with an adamantine luster, some of them clearly dominant and easily visible, and with Eglestonite crystals, a mineral species, product of alteration of other mercury minerals, an element that is also present in the specimen as small drops of native Mercury that hold together thanks to their high surface tension. The quality of this sample is exceptional, compared to other specimens from the same discovery. Both of the mercury halide species have been analyzed and we will send a copy of the analysis to the buyer. These minerals are photosensitive, blackening easily when exposed to sunlight and even under the light of a lamp, so we recommend keeping them out of the reach of light.
