16.65 Ct. Fluorite from South Africa

This 16.65 carat oval green fluorite presents precise lapidary engineering, measuring 18.29 x 14.59 x 10.77 mm, with an oval outline that balances presence and wearability. Cut as a mixed brilliant, the stone employs a brilliant style crown combined with a carefully proportioned step or modified pavilion to maximize internal light return and scintillation while maintaining a flat, generous table for clean windowing and visual access to the gem body. Color reads as very light intensity green, consistent across the table and facets, and the clarity grade is described as very very slightly included, evaluated at eye level, indicating only minimal natural inclusions that do not disrupt overall transparency or brilliance. Polish quality is excellent, resulting in crisp facet junctions and high facet luster, and there has been no enhancement applied to this gem, preserving its natural optical properties and elemental authenticity. The origin is South Africa, and provenance influences the crystal habit and zoning patterns that informed the cutting strategy, enabling the cutter to orient the rough to produce the most attractive hue and symmetry for an oval mixed brilliant.

The journey from mine to market for this fluorite is a controlled sequence of geological selection, careful sawing, and meticulous faceting under experienced hands, documented and curated by The Natural Gemstone Company. After extraction from a South African deposit, the rough was sorted for transparency and color homogeneity, then preformed to respect natural cleavage planes and to minimize loss of material. Master cutters then applied a faceting plan that prioritizes pavilion depth and crown angle relationships to enhance light performance while preserving weight and maximizing yield. Final stages included progressive sanding and a high degree polish with fine abrasives to achieve the excellent surface finish, followed by optical inspection under standard lighting to confirm the very very slightly included clarity at eye level and to ensure consistent color presentation. For practical use, the gem is best suited to designs that protect the girdle and table, given fluorite hardness on the Mohs scale, and it will reward settings that allow light to enter through the crown while shielding the pavilion from abrasion. The Natural Gemstone Company stands behind the documented origin, natural state, and technical grading of this piece, offering it as a rare, transparent example of South African green fluorite crafted for connoisseurs and experienced gem setters.
