Netopen Raw Diamond Rough Crystal Specimen 2.1ct — Natural Champagne

The Netopen Natural Champagne Raw Diamond Rough Crystal Specimen at 2.1 carats presents the warm, cognac-inflected color palette that results from a specific concentration of nitrogen atom substitutions within the carbon diamond lattice — a completely natural geological phenomenon that Netopen’s gemological team has verified through spectroscopic analysis to confirm that this color is entirely of natural origin and has not been produced through irradiation treatment, high-pressure high-temperature color enhancement, or any other artificial modification process. The champagne color in raw diamond rough carries particular collector appeal because it demonstrates one of the most common natural color mechanisms in diamond while appearing dramatically different from the conventional colorless gems seen in engagement ring settings — the rough crystal form makes this color origin story physically tangible in a way that a faceted and mounted stone never can. The crystal exhibits a dominant octahedral habit with secondary dodecahedral face development that creates the characteristic rounded triangular outline visible when viewing the specimen from the primary face — a formation detail that experienced mineral collectors recognize as indicative of a natural growth environment rather than a cleaved or sawn preparation. Internal features include natural feather inclusions, carbon spot inclusions, and growth zoning that are visible under 10x loupe magnification as geological signatures of the crystal’s formation history. Surface luster is natural vitreous with trigon etch pits and growth step features on the primary faces. Dimensions approximately 6.8mm x 6.5mm x 6.1mm. Mohs hardness 10. Supplied in Netopen’s signature rigid presentation box with velvet insert, gemological certificate specifying color origin as natural untreated, provenance documentation, and loupe for initial examination included as a collector’s aid.
