7.47 Ct. Emerald from Zambia

This heart shaped emerald presents an exacting combination of size, proportion, and finish that will appeal to collectors and gemsetters who prioritize optical performance. The stone weighs 7.47 carat, and measures 13.55 by 14.04 by 6.52 millimeters. It is faceted in a mixed brilliant scheme tailored to the heart silhouette, employing a brilliant pattern in the crown and a faceted pavilion plan that maximizes return of light while preserving the saturated face up color. The cutting emphasizes symmetry of the lobes and a well centered cleft to maintain the classic heart silhouette at this scale, and the overall depth of 6.52 millimeters produces a depth ratio of approximately 47 percent, a proportion that balances face up spread with depth for robust color concentration. The polish is graded excellent, yielding crisp facet junctions and lively facet reflections across the table and crown facets. The result is a stone that reads as transparent in hand, while the mixed brilliant faceting produces focused scintillation and a steady play of light that complements the emeralds inherent color saturation.

Color is the defining attribute of this piece, and the gem exhibits vivid color intensity in the green range, with a tone that sits in the medium to medium dark band favored by connoisseurs. The saturation is strong and even across the pavilion and crown, producing a saturated face up presence without appearing overly dark in typical lighting. Emeralds are pleochroic, and this specimen will show subtle variation in color when viewed from different crystallographic directions, so orientation in a mounting will materially affect the perceived hue and tone. The stone displays the kind of pure green with a balanced blue component that consigns it to the vivid category in practical grading terms. Optically the gem benefits from the refractive index characteristics of beryl, which typically fall in the range of approximately 1.57 to 1.58, and from a modest birefringence that does not interfere with clarity or brilliance. The mixed brilliant cutting optimizes light return within these optical parameters, delivering both depth of color and lively facet contrast that make the heart shape visually engaging in both still and moving light.

Clarity is assessed as slightly included when evaluated at eye level, a realistic and acceptable clarity grade for natural emeralds of this size and origin. Inclusions are consistent with natural emerald formation, often manifesting as fine needles, thin healed fissures, and small three phase or two phase pockets that form the typical jardin. These internal characteristics do not detract from the overall transparency, and they are in many ways evidence of natural origin and geological authenticity. The stone has undergone standard enhancement, a routine and disclosed practice in the trade, which typically involves the use of natural oils or low index organic resins to reduce the visual impact of surface reaching fissures and to improve apparent clarity. This enhancement is stable under normal wear conditions when the piece is appropriately set and cared for, but it does require informed handling. The Natural Emerald Company fully discloses this treatment and provides documentation so that buyers understand the nature of the enhancement and its implications. For longevity we recommend settings that protect the girdle and table from direct impact, routine inspections by a qualified lapidary, and avoidance of aggressive cleaning methods, as ultrasonic or steam treatments can affect surface fillings. Periodic professional evaluation will preserve the stone s appearance and ensure the enhancement remains intact.

Sourced from Zambia, this emerald aligns with the priorities of the conscious buyer who expects traceability and ethical labor practices in the supply chain. The Natural Emerald Company sources stones through vetted channels in Zambia, emphasizing chain of custody, supplier audits, and transparent documentation that establishes origin and treatment history. Sourcing from artisanal and industrial operations in the region requires careful vetting to ensure fair compensation for miners, adherence to local environmental protocols, and investment in community benefits where feasible. For the collector focused on ethical provenance this emerald can be incorporated into a conscious collection by pairing it with responsibly sourced metals and recycled mounting materials, by requesting detailed origin and treatment documentation at time of purchase, and by choosing settings that promote longevity and reparability over disposable design. The heart shape and substantial 7.47 carat weight make this stone ideal for a statement pendant or a bespoke commission that combines aesthetic impact with verifiable provenance. The Natural Emerald Company stands ready to assist with setting recommendations that protect the gem and highlight its vivid color, and with certification services and bespoke packaging that reflects a commitment to transparency and responsible gem stewardship.
