Netopen Raw Diamond Rough Crystal Specimen 2.3ct — Natural Champagne Dodecahedron

The Netopen Natural Champagne Raw Diamond Rough Crystal Specimen at 2.3 carats in dodecahedral habit offers a geological narrative distinct from the more commonly illustrated octahedral form — the dodecahedron, whose twelve curved triangular faces develop when a diamond crystal has experienced significant dissolution during its geological history, with the original sharp octahedral faces retreating and rounding as the dissolution process preferentially removes material from the face centers, leaving the characteristic bulging, rounded-triangular outline that geologists recognize as indicative of either prolonged mantle residence at specific pressure-temperature conditions or post-eruption chemical weathering during alluvial transport in kimberlite erosion systems. The dodecahedral form is therefore geologically informative in a way distinct from the octahedron — it records a longer or more chemically active post-growth geological history and is characteristically associated with alluvially transported rough diamonds that have spent time in river systems where chemical dissolution continues alongside mechanical rounding. The champagne color of this specimen — the warm brown-gold resulting from nitrogen aggregation defects — combines with the rounded dissolution surfaces to create an aesthetically warm and organically shaped specimen that many collectors find more approachable and less technically imposing than the sharper geometry of well-formed octahedral rough. Natural dissolution surfaces show characteristic curved forms and minor surface pitting consistent with genuine dissolution history. Color is consistent and warm throughout the crystal body. Dimensions approximately 7.2mm x 6.9mm x 6.5mm. Geological documentation explaining the dodecahedral dissolution mechanism and its significance for understanding diamond geological history supplied alongside standard gemological certificate, conflict-free provenance, and Netopen presentation box.
