6.28 Ct. Emerald from Zambia

Deep within the Proterozoic crust of what is now Zambia, hydrothermal beryllium bearing fluids migrated into silica rich host rocks and reacted with chromium and vanadium bearing minerals to nucleate beryl crystals over millions of years. Under elevated pressures and temperatures, growth occurred in episodic pulses, producing elongated crystal habits with internal growth zoning and characteristic inclusions. This emerald completed its growth in a vanadium influenced environment that imparts a pronounced, intense green hue, the color preserved by a compact crystalline lattice during subsequent uplift and erosion. The Natural Emerald Company presents this gem as a geological narrative, a 6.28 carat cushion shaped emerald that embodies its deep time origin and the specific geochemical fingerprint of Zambian deposits.

Cut and finished to exacting standards, the emerald measures 13.34 by 9.49 by 6.83 millimeters, yielding a depth ratio of approximately sixty percent, a proportion that balances face up color saturation with light return. The cutting style is faceted, executed as a mixed brilliant cut that combines a faceted crown geometry optimized for scintillation, with a pavilion treatment that preserves weight and chroma. Facet junctions are clean and symmetrical, and the polish is evaluated as excellent, producing crisp windowing at facet edges and a lively play of light without sacrificing the stone is intrinsic color. Clarity is graded slightly included at eye level, with fine natural internal features that provide diagnostic character and do not substantially impede transparency. Enhancement is standard, performed to stabilize surface reaching fissures and to improve apparent clarity in a manner consistent with trade practice for large emeralds.

As a specialist offering, The Natural Emerald Company recommends settings that protect the pavilion and corners of the cushion outline, such as low profile prong or partial bezel mounts, in warm gold alloys that enhance the green chroma. The mixed brilliant faceting and the intense color intensity make this gem an ideal candidate for a statement ring or a pendant where face up presence is paramount. For clients who require additional documentation, high resolution imaging and laboratory reporting can be provided, and our team is available to advise on setting, care, and certification to ensure this Zambian emerald is presented and preserved to exacting standards.
