Netopen Raw Diamond Rough Crystal Specimen 4.8ct — Natural White Premier Grade

The Netopen Natural White Raw Diamond Rough Crystal Specimen at 4.8 carats in Premier Grade designation represents the tier within Netopen’s collection where size, color quality, crystal form, and internal clarity combine at levels that independent gemological assessment identifies as significantly above the standard rough market for equivalent carat weights — placing this specimen in the category that serious rough diamond investors and high-level private collectors target when building portfolios of authenticated natural rough diamond material with documented provenance and independent valuation. The Premier Grade designation at Netopen requires independent assessment by a contracted GIA-certified gemologist in addition to Netopen’s internal gemological evaluation, creating a two-level verification of the quality claims that the Premier Grade implies and providing the independent documentation that institutional buyers and sophisticated private collectors require as a baseline standard for acquisition confidence. The 4.8ct white specimen assessed at Premier Grade in this listing meets the following minimum criteria applied in the Premier Grade classification: equivalent near-colorless to colorless color range (D-F equivalent in rough assessment), VS-equivalent or better internal clarity in rough assessment, complete or near-complete crystal habit with no major cleavage or fracture disruption of the crystal form, and exceptional surface feature variety providing educational and aesthetic value above standard rough at this carat weight. This specific specimen shows a well-developed octahedral habit with excellent geometric regularity, natural trigon etch pits of uniform distribution on primary faces, near-colorless body color in transmitted and reflected light, and VS-equivalent internal clarity with minor natural inclusions visible at 10x magnification. Dimensions approximately 10.5mm x 10.1mm x 9.7mm. Independent GIA-certified gemologist assessment report, Netopen Premier Grade certificate, Kimberley Process compliance documentation, conflict-free supply chain audit, and premium leather presentation case with professional gemological tools supplied.
