3.65 lbs Tangerine Hematoid Quartz with Wulfenite (3 pcs) - Collector Minerals L305
This set brings together an especially complete and sought-after oxidation-zone association: Hematoid Quartz in its Tangerine variety accompanied by Wulfenite, with the addition of cavities lined with translucent amber-honey quartz and zones of milky white quartz. The term Tangerine designates quartz crystals coated by a thin granular layer of limonite and goethite that gives them that vibrant tangerine-orange and golden color, while Wulfenite (lead molybdate, formula PbMoO4) provides the striking lemon-yellow to yellow-golden acicular and prismatic crystals, with adamantine to resinous luster, scattered over the matrix and on the edges of the cavities: a secondary lead mineral highly prized by collectors and typical of gossans. The combination of both on the quartz makes this lot a piece of great mineralogical and aesthetic interest.
The lot consists of 3 good-sized pieces with a combined weight of 3.65 lbs (1.657 kg), making them specimens of great presence, ideal both for prominent display in a showcase and for detailed study. As spectacularly revealed by the macro photographs, the pieces show a multiple visual richness: on the one hand, the granular orange-amber tangerine coating on the quartz faces; on the other, the ferruginous matrix or gossan in ochre-brown to dark-brown that serves as support; the lemon-yellow acicular and prismatic crystals of wulfenite, now perfectly visible, that dot the surface and the lips of the hollows, providing an adamantine luster and a highly valued microscopic detail; and finally, geode cavities lined with crystals of translucent amber-honey and orange quartz with color zoning, with notable vitreous luster, framed by milky white quartz that provides luminosity and depth, with additional patches of brilliant yellow-golden wulfenite on their edges.
From the point of view of its formation, this specimen is an excellent geological document of a supergene paragenesis: first the quartz crystallized (white and amber zones in cavities); then, in the oxidation phase and fluid circulation, iron oxides (limonite and goethite, generating the tangerine and the gossan) precipitated on the quartz and the matrix and, under the same oxidizing conditions, wulfenite from the mobilized lead and molybdenum, crystallizing in its characteristic acicular and prismatic yellow habits. That superposition of phases explains the play of colors and textures observed and gives the piece its three-dimensional character and its high educational value, by illustrating in a single specimen the crystallization of quartz and the secondary mineralization of iron and lead.
The contrast between the rustic opacity of the gossan, the warmth of the tangerine, the lemon-yellow adamantine luster of the wulfenite and the luminous transparency of the amber quartz of the cavities creates a very balanced and elegant visual effect. Due to its color, contrast, confirmed presence of acicular wulfenite, zoned cavities and size, this lot constitutes an exceptional opportunity for the collector looking for pieces with character, warm natural color and a visually very complete oxidation mineralogy, perfect both for mineralogical study and for prominent display in any collection.
