0.31ct Untreated Natural Fancy Diamond Loose Gemstone, 71BH
This fully polished untreated natural fancy diamond features inherent internal mineral markings characteristic of natural diamond formation, measured at calibrated dimensions of 4.2x3.7x1.9mm. Precision faceting encourages natural light interaction, showcasing the unique colour character locked within its crystal lattice, completely finished and ready for setting into distinctive artisan fine jewellery. Fancy coloured diamonds represent an exceptionally scarce subset of all natural diamond production. Roughly less than 1 out of every 10,000 mined natural diamonds qualifies as a natural fancy diamond, while colourless to near-colourless white diamonds constitute the vast majority of commercial diamond output. The formation of natural fancy colouration relies on rare trace element contamination or structural lattice distortion deep within the earth during crystallisation, geological conditions that occur far less frequently than those creating standard white diamond. Untreated specimens carry additional collector weight, as their colour is wholly natural rather than artificially modified. Untreated natural fancy diamond. Natural mineral inclusions and internal growth features visible under magnification; no irradiation, heating or colour enhancement treatments applied.
