Description: There are crystals that are clear, and then there are crystals that redefine what clarity means. This Genuine Herkimer Diamond presents itself with such internal purity that, at first glance, it evokes the optical precision of a faceted diamond suspended in natural form. Light does not merely pass through it, it travels uninterrupted from one termination to the other, as though the crystal were a conduit rather than a mineral. Formed in Herkimer County, New York, this specimen displays the classic double terminated habit for which these crystals are internationally recognised. Its proportions are distinctly needle like, elongated and refined, with both terminations perfectly developed and sharply defined. The edges are crisp, the faces well structured, and the symmetry remarkably balanced for a crystal of this slender format. What truly elevates this piece is its complete absence of internal inclusions. Under magnification and to the naked eye, the interior remains entirely clean. No veils, no bubbles, no fractures interrupt the optical pathway. The internal space appears open and transparent in a way that is exceptionally rare, even among high grade Herkimer Diamonds. This level of crystal cleanliness dramatically increases both aesthetic and collector value. Transparency is extraordinary. When backlit, the crystal allows full light transmission from one point to the other, emphasising its needle geometry and reinforcing the impression of diamond like optical behaviour. The natural surfaces remain untouched, preserving fine growth features that confirm its geological authenticity without compromising internal perfection. This is not simply a well formed specimen. It is an example of structural precision combined with near absolute clarity, a crystal that stands at the highest end of what Herkimer material can offer.

Most specimens display inclusions, internal veils or minor growth interruptions. A crystal that is entirely clean internally, especially in a slender double terminated needle form, occupies a far narrower category of availability. Collectors who pursue clarity driven specimens will immediately recognise the significance of this example. Its optical behaviour approaches that of fine faceted gemstones, yet it remains entirely natural and untouched. For advanced collectors, this is not about size, it is about internal perfection, symmetry and provenance. Crystals at this clarity level from Herkimer County are increasingly difficult to source in consistent quality. Lapidary Potential: While technically capable of being incorporated into fine jewellery due to its internal purity and optical clarity, any intervention would permanently sacrifice its natural double termination and needle geometry. Its highest value lies in its preserved natural state, where the combination of flawless interior, structural precision and complete terminations can be fully appreciated. In this form, it expresses its identity with honesty and architectural elegance, exactly as it crystallised millions of years ago. ——————— Shipping and Handling: All orders are shipped by Portuguese National Post. • Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki • Transit time with CTT service: between 5 to 7 business days within europe and worldwide, depending on destination national post. • A tracking number is always provided Photography and transparency: All photographs are taken under controlled lighting conditions using a macro lens, carefully selected to present each specimen as accurately as possible. No filters, colour enhancement, or artificial saturation are applied. The lighting setup uses a calibrated 5500K light source, replicating neutral daylight to reveal natural tones, surface features, and internal characteristics. Under warmer or weaker indoor lighting, colours may appear slightly different, which is normal. The purpose of this photographic process is documentation and representation, not visual enhancement. Images are intended to reflect the specimen faithfully as it appears under balanced natural light conditions. Identification and ethics: All specimens offered are natural and described to the best of our knowledge, based on direct sourcing, professional experience, and information provided by trusted suppliers working at the origin. Every effort is made to ensure transparency and accuracy regarding identification, locality, and general characteristics, avoiding misleading statements about treatment, provenance, or nature. Customs and import taxes: Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder. These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities. Guarantee and resolution: Customer satisfaction is important.

Each case is handled individually and fairly, with appropriate solutions offered when justified. Appreciation and commitment: We sincerely thank you for your trust. Our work focuses on careful selection, accurate representation, and respectful presentation of mineral specimens with character and interest. Each piece is chosen for its individual qualities rather than speculative or financial considerations. We aim to provide a transparent, reliable, and consistent experience for collectors at all levels. With gratitude, GemPulse Minerals
