RARE lot of 10 Herkimer Diamonds — 6.30 carats...

Exceptional lot of 10 natural Herkimer Diamonds, bringing together a remarkable selection with morphologies that are particularly varied and complex. Although their dimensions range from only about 5 to 7 mm, each one presents a genuine individual architecture: compact or elongated shapes, clearly expressed terminations, large natural reflective faces, zones of beautiful transparency, and internal structures that are sometimes extremely developed. Their observation reveals an astonishing diversity of veils, inclusions, natural fractures, and growth planes, giving each crystal an absolutely unique character. The gathering of 10 distinct individuals mainly allows us to appreciate the full variety that a single family of crystallizations can produce: no piece is truly identical to its neighbor. With a total of 6.30 carats, the average weight is about 0.63 carat per specimen. These are extremely rare specimens of double-terminated quartz, sought after under the name “Herkimer Diamonds” for their spectacular natural geometry, their transparency, and their characteristic brilliance. Characteristics - Collection name: Herkimer Diamonds - Number of specimens: 10 - Mineral nature: Natural double-terminated quartz - Origin: Pakistan - Total weight: 6.30 carats - Average weight: ≈ 0.63 carat per specimen - Dimensions: Approximately 5 to 7 mm - Morphology: Natural double-terminated crystals - Color: Colorless, with locally slight nuances due to natural inclusions - Transparency: Transparent to locally translucent - Luster: Intense vitreous - Crystallization: Natural - Terminations: Natural, variable per specimen - Internal structure: Veils, fractures, inclusions and natural growth planes - Condition: Natural, uncut specimens - Interest: Mineral collection, crystallography, loupe observation and macrophotography A true collection of 10 specimens The appeal of this set lies primarily in the number and remarkable diversity of the crystals gathered. Presented side by side, the ten specimens immediately show how natural growth can produce very different architectures. Some crystals develop a short, stout silhouette, others are more elongated; some have large transparent zones while others concentrate a multitude of internal structures. This diversity transforms the lot into a genuine miniature mineralogical collection, rather than a simple gathering of similar crystals. A fascinating natural geometry One of the most spectacular features of these crystals is their almost faceted appearance. Their flat faces, edges, and terminations are nonetheless the result of natural crystal growth. No cutting work is necessary to produce this geometric architecture. Under directional lighting, each change of orientation reveals new reflections. Some faces become perfectly transparent while others reflect light like tiny mirrors. At this scale, this natural precision is particularly impressive. Exceptional complexity concentrated in a few millimeters The contrast between the small dimensions of these specimens and the richness of their structures is one of the major interests of the lot. In only 5 to 7 mm, some crystals harbor a true network of internal structures. Zones that are perfectly clear can sit alongside veils, inclusions, natural fractures, or different growth planes. These elements interact with light and give surprising depth to the specimens. To the naked eye, they appear as tiny, brilliantly bright crystals. Under a loupe or macro lens, they reveal a much more complex universe. Ten different growth stories Each crystal also bears witness to an individual geological history. During its formation, surrounding conditions could have evolved. Successive changes may leave different traces in the crystal: growth variations, inclusions, natural fractures, or distinctive internal structures. This is precisely why two specimens never develop exactly the same internal landscape. With 10 crystals gathered, this lot allows observing ten different expressions of this natural process. The history of the “Herkimer Diamonds” The name “Herkimer Diamond” is historically linked to the famous double-terminated crystals discovered in Herkimer County and the neighboring regions of New York State. Their transparency, particularly vivid brilliance, and naturally geometric morphology earned them this historical comparison with diamond. They have gradually become iconic crystals in the world of collector mineralogy. Comparable double-terminated crystallizations are also found in different regions around the world. It is therefore important to distinguish the traditional collection name from the actual geographic provenance, which is precisely indicated in the characteristics of this lot. A particularly interesting selection for observation The miniature format of these specimens gives them special interest for magnified observation. With a loupe, the large natural faces become true windows into the internal structures. In macrophotography, the smallest details take on spectacular proportions and reveal architectures difficult to perceive with the naked eye. The presence of ten crystals also allows comparing differences in transparency, morphology, termination, and internal structure within a single set. 0.63 carat average per crystal With 6.30 carats spread across 10 specimens, each crystal weighs an average of about 0.63 carat. This figure underscores the truly miniature nature of the selection: a complete crystalline architecture, and sometimes extremely complex, is contained in an average mass of less than one carat. The dimensions of about 5 to 7 mm also make the set visually very homogeneous, while retaining enough variation for each crystal to be immediately identifiable. A remarkable set for the collector Thus this lot offers an opportunity to gather in a single purchase 10 distinct natural specimens, each with its own morphology, its own terminations, and its own internal landscape. The combination of the number of crystals, their beautiful transparency, their luster, their morphological diversity, and their internal complexity makes this a particularly interesting set for the collector who appreciates miniature crystallizations. 10 natural specimens – 6.30 carats total – about 0.63 carat per crystal – 5 to 7 mm: ten unique natural architectures gathered in a true miniature collection.
