Both terminations are clearly formed, sharp and intact, giving the crystal a strong axial presence that immediately reflects its authentic Herkimer origin. The crystal displays a distinct contrast between its opposing zones. One half reveals a markedly vitreous clarity, offering transparent windows into the interior where natural growth features and fine internal textures can be observed with precision. These clearer sections interact vividly with light, producing sharp internal reflections and a sense of depth that enhances the specimen’s visual authority. The opposite half shows a more textured structure, preserving natural growth markings and subtle surface features that speak directly to its undisturbed formation within the host rock. Its elongated form accentuates the natural symmetry between the two terminations, while the internal landscape remains expressive without overwhelming the clarity. When observed under direct light, the more vitreous areas act as optical corridors, drawing light through the crystal and illuminating internal veils and growth planes, while the denser zones provide contrast and mineralogical character. This specimen offers a compelling balance between optical purity and raw natural expression. It is a Herkimer Diamond that rewards careful observation, combining structural integrity, authentic locality and an elegant interplay between clarity and texture that defines high quality material from this classic American deposit.

This specimen combines true locality, structural completeness and optical contrast, making it a refined and desirable piece for collectors focused on classic North American mineral localities and genuine crystal morphology. Lapidary Potential: While select areas display appealing transparency, the crystal’s true value resides in its complete natural form and preserved double termination. Any cutting would compromise its symmetry and mineralogical integrity. For this reason, its highest value is best maintained as a natural specimen, where its structure, terminations and internal features can be fully appreciated in their original state. ————— Shipping and Handling: All orders are shipped by UPS express or National Express. • Dispatch time: within 1 to 2 business days after payment confirmation to Catawiki • Transit time with Express service: up to 3 business days within europe and worldwide • A tracking number is always provided Photography and transparency: All photos were taken under controlled light conditions, carefully selected to reproduce the most accurate natural colour of each specimen.
