5.56 Ct. Fluorite from China

I have always believed that every gemstone carries a story before it becomes jewelry, and this 5.56 carat emerald cut bi color fluorite begins its tale far below the surface of the earth where heat, pressure, and time conspire to lay down layers of color. Mined in China, this specimen was born in veins where fluorite crystals grew slowly in cavities, each growth episode leaving an imprint of changing chemistry and temperature. Those subtle shifts produced the delicate green to yellow zoning you see, a visual record of mineral-rich fluids ebbing and flowing over millennia. The result is a transparent gem with a medium color intensity that feels alive, as if light passes through and carries a small fragment of geological history. As your guide from The Natural Gemstone Company I value the sense of connection that comes from knowing a gem’s origin, and this stone’s Chinese provenance contributes both to its character and to its narrative appeal, linking the modern wearer to a long tradition of appreciation for fluorite in East Asian lapidary arts.

When the rough crystal reached our cutters it was selected specifically for its clarity and color zoning, then given a classical emerald cut to emphasize both transparency and the interplay of hues. The dimensions are 10.96 by 9.03 by 6.42 millimeters, proportions that give the gem presence without overwhelming a design. The emerald cut, with its broad step facets and truncated corners, creates a window effect that showcases the bi-color transition from green to yellow while masking some internal features, making this cut an ideal choice for slightly included material evaluated at eye level. The clarity grade is slightly included, which means there are minor inclusions visible to a trained eye but they do not detract from the gem’s overall brilliance and appeal, especially given its excellent polish. The cutter’s skill is evident in the clean facet junctions and crisp lines, finished to a high polish that maximizes light return and allows the medium color intensity to glow consistently across the table.

To present the gem at its best we used heat treatment, a standard and widely accepted enhancement in the trade, applied to stabilize and subtly deepen color where appropriate. This enhancement is disclosed and documented, and in this case it brings forward the bi-color character while preserving the natural zoning that makes the specimen unique. The fact that this fluorite comes from China adds value beyond the physical attributes, because Chinese fluorite sources are known for producing material with exceptional transparency and interesting color patterns, and because of a legacy of skilled lapidary work in the region. Provenance matters in stones like this, where the combination of natural formation, regional characteristics, and human craftsmanship together create a gem of uncommon personality. Collectors and connoisseurs prize such provenance because it ties the gem to a place and a tradition, and in practical terms it also helps assure traceability and quality standards that The Natural Gemstone Company stands behind.

Imagine this emerald cut bi color fluorite set as the centerpiece of a custom ring or a pendant, where the step cut will direct the viewer’s gaze into the stone and reveal changing tones as it catches the light. Its weight of 5.56 carats and comfortable dimensions make it versatile for a statement ring or a distinctive pendant that plays with color in a subtle, sophisticated way. Because fluorite is relatively soft compared with corundum and diamond, I recommend protective settings such as bezel or halo designs for everyday wear, along with gentle care practices, avoiding harsh chemicals and sudden temperature changes to preserve the polish and the effect of the heat treatment. At The Natural Gemstone Company we can provide guidance on mounting, offer bespoke design services, and supply documentation about the gem’s characteristics, treatment, and origin. Owning this bi color fluorite means carrying a piece of the earth’s layered history, enhanced by skillful cutting and a touch of heat treatment, and presented with the provenance and responsible sourcing you expect from our atelier.
