Netopen Raw Diamond Rough Crystal Specimen 4.5ct — Natural White Octahedron

The Netopen Natural White Raw Diamond Rough Crystal Specimen at 4.5 carats represents the upper tier of Netopen’s rough diamond collection — a large-format natural diamond crystal of near-colorless character that, if submitted for conventional faceted grading, would fall within the D-F color range indicative of exceptional colorlessness and maximum light transmission in the visible spectrum. The octahedral crystal habit is fully developed and visually classic — the two four-sided pyramids meeting at a shared equatorial plane that make the octahedron the most geometrically recognizable natural diamond crystal form, and the form that directly inspired the earliest brilliant cut designs as early lapidaries recognized that an octahedron placed point-down into a turning could be polished to create the round brilliant outline with minimal material loss. At 4.5 carats, this specimen occupies the size range where rough diamonds begin to attract serious collector and investment interest — large enough to convey genuine scale, rare enough at this color quality level to represent a meaningful geological event. The crystal surfaces show natural satin-matte texture resulting from the micro-textured surface features that develop during the diamond’s transport through kimberlite pipe material — surface trigon etch pits, micro-hillocks, and the characteristic adamantine luster that distinguishes uncut diamond from all other minerals regardless of color or clarity. Internal features are minimal at this color grade — scattered minor pinpoint inclusions visible at 10x magnification that document the crystal’s natural formation history without compromising the visual impact of the specimen. Dimensions approximately 9.8mm x 9.5mm x 9.2mm. Weight verified on calibrated gemological balance. Supplied in Netopen’s premium large-format presentation box with fitted velvet insert, full gemological certificate, conflict-free provenance documentation, professional 10x loupe, and comprehensive collector’s reference guide.
