Netopen Raw Diamond Rough Crystal Specimen 2.4ct — Natural Olive Green

The Netopen Natural Olive Green Raw Diamond Rough Crystal Specimen at 2.4 carats presents one of the geologically most fascinating color phenomena in the natural diamond category — the surface radiation green color that develops when a diamond is exposed to natural radioactive emissions from surrounding mineral deposits or groundwater over geological timescales, creating a damaged zone in the near-surface diamond lattice where radiation-induced defect centers absorb red wavelengths and transmit the green responsible for the distinctive olive green surface coloring. This surface radiation green color is strictly a near-surface phenomenon — typically penetrating only a fraction of a millimeter into the diamond crystal body — which means that the interior of a radiation-green rough diamond is typically colorless or nearly so, and that if the stone were cut and polished to remove the surface, the green color would be eliminated entirely. This characteristic makes radiation green diamonds essentially unique in the rough form: the color exists because the diamond remains uncut. Netopen’s gemological assessment has confirmed this specimen as displaying natural radiation-induced surface green color, distinguishing it from irradiation-treated stones that have received artificial gamma or electron irradiation to produce similar but artificially induced color throughout the crystal body. The distinction is critical for collector value and disclosure — naturally radiation-green rough diamonds require the same disclosure of their color cause as any treated stone, and Netopen provides complete documentation of the natural geological mechanism responsible. The crystal habit is predominantly dodecahedral with rounded dissolution surfaces. Surface color distribution is heterogeneous as expected for natural radiation exposure — more intense at specific surface zones that faced the radioactive source during geological exposure. Dimensions approximately 7.4mm x 7.0mm x 6.7mm. Full scientific documentation of radiation color mechanism included with gemological certificate.
