1.58 Ct. Emerald from Nigeria

This 1.58 carat, transparent green emerald is masterfully presented in a classical emerald cut, with finished dimensions of 9.15 by 5.17 by 4.23 millimeters. The proportions yield a length to width ratio of approximately 1.77, producing an elegant elongated silhouette that reads modern yet timeless in a range of settings. Measured depth of roughly 59 percent places the pavilion within the typical window for step cut emeralds, allowing for an optimal balance between apparent color saturation and light transmission. The emerald cut itself features broad rectangular step facets and truncated corners, which preserve carat weight while creating the long, polished facet planes that emphasize color and internal character rather than brilliant facet scintillation. An excellent polish has been executed across pavilion and crown facets, producing crisp facet junctions, uniform facet symmetry, and a fine, satiny luster on table and girdle that enhances the gem’s transparency and visual depth.

Color and clarity are described with precise, gemological language to set expectations for discerning buyers. The stone exhibits a light color intensity, a clear, fresh green with bluish undertones typical of high quality Nigerian material. Because this is an emerald and not a beryl cut to maximize brilliance, the emerald cut directs attention to body color and internal features rather than sparkle. Clarity is graded as slightly included at eye level, reflecting the presence of natural inclusions consistent with emerald formation, including fine three phase inclusions and thin internal fissures that are visible under standard viewing but do not detract from transparency. Enhancement is standard, the industry term indicating a typical clarity treatment applied to improve apparent clarity and stability. This treatment is stable under normal wear, but like all emeralds may require periodic maintenance to preserve appearance. The gem’s transparent character and light color intensity combine to produce a lively, fresh green that remains versatile in design.

Origin and ethical sourcing are integral to the value proposition offered by The Natural Emerald Company. This emerald originates from Nigeria, sourced through our vetted network of local partners and miners who operate under our responsible sourcing protocol. We prioritize direct relationships that enable traceability from mine to market, adherence to local labor and environmental standards, and investment in community initiatives. Each step of the supply chain is documented, with origin disclosure and chain of custody maintained to assure buyers that the gem was extracted and traded in compliance with our ethical guidelines. For the conscious collector, provenance matters as much as provenance clarity. The Natural Emerald Company provides transparent accounts of sourcing practices, ensures fair compensation for artisanal miners where applicable, and supports small scale mining communities through targeted programs that mitigate environmental impact and fund local development. We encourage buyers seeking verifiable ethical provenance to request our sourcing statement and documentation on specific lots.

From a design and care perspective this emerald is highly adaptable while requiring informed handling to maximize longevity. The emerald cut and the gem’s elongated dimensions are ideal for a solitaire ring with a protective setting, a fine bezel, or a halo design that emphasizes length and linearity. Given the slightly included clarity and the stepped faceting which concentrates light reflections, settings that protect the girdle and corners are recommended, for example, low profile bezels or four cornered collet constructions to reduce the risk of edge chipping. This gem’s hardness and toughness are consistent with emerald as a species, yet it benefits from protective mounting and avoidance of impact. Routine care recommendations include gentle cleaning with mild soap and warm water, avoidance of harsh chemicals and prolonged exposure to heat, and professional inspection for reapplication of any clarity enhancement if needed. For collectors focused on responsible luxury, this piece combines technical refinement in cut and polish with a clear ethical story from a reputable supplier. The Natural Emerald Company stands behind the gem’s quality, documented origin, and responsible sourcing practices, offering a transparent choice for the principled buyer who values both craftsmanship and conscience.
