Netopen Raw Diamond Rough Crystal Specimen 1.5ct — Natural White

The Netopen Natural White Raw Diamond Rough Crystal Specimen at 1.5 carats delivers the authentic geological character of a diamond in its most elemental form — uncut, unpolished, and entirely untouched by the lapidary process that transforms rough crystal into the faceted gemstones seen in conventional jewelry. This specimen has been extracted from certified conflict-free alluvial and kimberlite sources and passes through Netopen’s multi-stage provenance verification process before reaching the collector, ensuring that the geological authenticity of the stone is matched by the ethical integrity of its supply chain. The crystal formation is a naturally occurring octahedron — the most common and visually iconic form in which diamond crystallizes from the high-pressure, high-temperature environment of the Earth’s mantle, at depths exceeding 150 kilometers below the surface over geological timescales of one to three billion years. The natural white color results from an exceptionally pure carbon lattice with minimal structural inclusions or trace element substitutions that would produce color in the visible spectrum. Visible surface features include natural trigon etch pits — the triangular dissolution features that develop on octahedral faces during the crystal’s journey from the mantle to the surface through kimberlite pipe eruption — along with growth steps, minor surface irregularities, and the natural vitreous luster of unpolished diamond crystal faces that distinguishes authentic rough diamonds from synthetic simulants or polished goods. Dimensions approximately 5.8mm x 5.5mm x 5.2mm. Mohs hardness 10. Refractive index 2.417. Each specimen is individually assessed and assigned a reference number linked to its provenance documentation. Supplied in a Netopen branded rigid presentation box with fitted velvet insert, gemological certificate of authenticity, provenance documentation, and printed care and handling guide. This specimen is suited to serious mineral collectors, investment-grade rough diamond buyers, geology educators, and individuals seeking an authentic unprocessed diamond with documented natural origin.
