3.44 lbs Pink Garnet from Coahuila (2 pcs) - Collector Minerals L186
This extraordinary set represents one of the most prestigious mineral associations in Mexico: Grossularite (Pink Garnet) from the state of Coahuila, specifically from the Sierra de Cruces region in the municipality of Múzquiz. This locality is internationally recognized for producing some of the most beautiful and largest pink garnets, formed in skarn environments (metamorphic contact rocks).
The lot consists of 2 generously sized pieces, with a combined weight of 3.44 lbs, making them ideal specimens for display in a showcase. The grossularite crystals display their characteristic intense pink to magenta color, with tones ranging from light pink to deep ruby red, often showing notable transparency and vitreous to adamantine luster. The crystals, with the typical cubic and trapezohedral habit of garnets from the isometric system, are disseminated and clustered on a white and grayish matrix, composed mainly of calcite, wollastonite and other skarn minerals, with some inclusions of dark minerals (possibly magnetite or chlorite) that provide additional visual contrast.
The combination of the vibrant pink of the garnets against the light background of the skarn matrix creates an exceptional aesthetic effect, highly appreciated in international mineral collecting. These specimens possess significant scientific value, as Coahuila garnets are studied for their unique chemical composition (rich in calcium and aluminum) and the special geological conditions of contact metamorphism that allowed their formation in the zone of igneous rock intrusion into limestones.
As revealed by the photographs, each piece offers a unique distribution of crystals, with areas of high concentration of good-sized garnets and others where the skarn matrix predominates, providing a complete and varied visual experience. It is an exceptional selection for serious collectors looking for representative specimens from this classic Mexican locality, perfect for both mineralogical study and prominent display in any collection.
