9.37 Ct. Fluorite from China

This remarkable transparent bi color fluorite from China presents as a generous 9.37 carat gemstone, measuring 13.98 x 10.02 x 7.88 mm, and it carries an emerald cut that immediately signals refined geometry and deliberate optical design. At The Natural Gemstone Company we select material that shows both intense color intensity and a clarity grade of very slightly included when evaluated at eye level, attributes that are uncommon in fluorite of this size. The stone has been heat treated to enhance stability and deepen the visual saturation, and it has been finished to an excellent polish that preserves crisp facet junctions and a mirror like table. Compared with other fluorite pieces on the market this gem stands out for a rare combination of size, transparency, and color zoning that translates into a pronounced visual presence when set into jewelry or held for study. Customers who have compared our stones with mass market alternatives consistently report that the overall proportioning and surface finish of this emerald cut fluorite make it read larger and more luminous than many larger but roughly fashioned pieces.

The emerald cut geometry of this stone is the principal reason it performs so well under light, because the step cut planes and elongated table create broad facet surfaces that act like channels for light, guiding it across the interior and back to the eye. Unlike a brilliant cut that scatters light into many little flashes, the emerald cut emphasizes elegant flashes and broad spectral streaming, which is perfectly suited to a transparent, intensely colored fluorite. The precision of the pavilion and crown facets, the symmetry of the step facets, and the well proportioned table and depth yield maximum light play for this material. The bi color character is revealed differently depending on angle and intensity of illumination, and the geometric faceting makes these transitions appear clean and architectural rather than muddled. Excellent polish enhances this effect by eliminating surface diffusion and preserving crisp reflections, so that each planar facet functions as an efficient light conduit. In short, the cutting choices made for this gem turn its transparency and color into active optical properties, giving designers, collectors, and connoisseurs a stone that reads as both refined and theatrical when compared with more roughly cut or poorly polished fluorites.

Where many fluorites in the marketplace show soft color, heavy inclusions, or rounded cuts that hide potential brilliance, this specimen offers a marked step up in both quality and value. Fluorite is known for its relative softness compared with traditional jewelry gem materials, and that makes cutting quality and polish even more important because any surface scratches or poor facet junctions are far more noticeable. Our evaluation at The Natural Gemstone Company emphasizes eye level clarity, and the very slightly included grade here means the internal features serve as character lines rather than distractions, especially when framed by the emerald cut. Heat treatment has been applied in a controlled manner to stabilize and intensify color without compromising clarity, so buyers receive a visually arresting stone that will perform reliably in wearable settings when properly protected. Compared with synthetics or glass imitations that may mimic color but lack the depth of internal structure and natural zoning, authentic bi color fluorite with this degree of transparency and cutting detail communicates authenticity and value. Designers will appreciate that the precise geometry gives consistent visual results in a range of settings, making the stone easier to match with metals and accent stones while still delivering a unique visual signature.

Practical considerations make this fluorite an excellent investment for the right use, and we advise buyers on how to maximize longevity while enjoying the gem daily. Because fluorite is softer than many traditional gems buyers should favor protective settings such as bezel or partial bezel mounts and consider this gem as a statement pendant or as a ring in designs that position the stone away from impact zones. Polishing and routine inspection will preserve the excellent surface condition, and cleaning with a soft cloth and mild soapy water is recommended, while avoiding ultrasonic cleaners or harsh chemicals that can risk surface degradation. The provenance from China and the transparent disclosure of heat treatment are part of our commitment to honest representation, and The Natural Gemstone Company stands behind the description, cut quality, and polish of each stone we offer. For clients seeking a bi color fluorite that marries architectural cutting, sizable presence at 9.37 carat, and exceptional finish, this emerald cut specimen represents a rare combination of aesthetic and practical advantages that set it apart from more common market offerings.
