1.35 Ct. Emerald from Zambia

This emerald presents as a transparent, well proportioned 1.35 carat stone, fashioned in the classic emerald cut, with precise dimensions of 7.45 by 5.67 by 3.83 millimeters. The cutter has maintained a length to width ratio of approximately one point three one, a proportional window that preserves table size while maximizing the attractive step facet planes that define this shape. The pavilion depth measures such that the overall depth is approximately fifty eight percent of the average girdle span, a proportion that supports strong face up color saturation without collapsing the pavilion or producing a dark center. The corners are truncated in the traditional emerald cut manner, which reduces stress points and enhances durability for mounted work. This combination of weight and dimensions is uncommon for stones with the reported transparency and color intensity, and it positions this piece as an especially desirable option for collectors and designers seeking a medium sized focal gem with confident presence.

Under loupe and in hand inspection the faceting exhibits deliberate, technically exact step architecture, with broad crown steps flowing into graduated pavilion steps, and crisp facet junctions that evidence controlled facet alignment. The excellent polish ensures that facet planes deliver clean, mirror like reflections, minimizing surface diffusion and preserving the stone light return that is critical in step cuts. The table plane is generous, allowing a direct line of sight to the pavilion steps and to the internal structure, which aids in appraisal and in aesthetic evaluation by the wearer. Optically the emerald demonstrates the typical pleochroic behavior of natural emeralds, shifting between bluish green and yellowish green tones depending on orientation, an effect that the cutter has used to advantage by orienting the crystal axis for maximum face up saturation. Physically the material conforms to the known parameters for beryl, with a refractive index in the range of about 1.577 to 1.583, a modest birefringence, and a specific gravity around 2.72, all of which inform the stone handling and setting choices for jewelers.

Color and clarity are the critical attributes that make this specimen markedly rare for its scale and origin. The color is classified as intense, presenting a deep, vivid green with a balanced mixture of bluish green and pure green hues that reads evenly across the table and into the pavilion. This intensity is paired with a transparency described as transparent, and a clarity grade of very slightly included when evaluated at eye level. Those terms indicate that inclusions are minimal to the unaided eye, and when present they are localized and do not interfere with the overall saturation or the stone light performance. For Zambian emeralds, which are often admired for their deep, cooler green tones and pronounced color saturation, a one point three five carat example that also reads as transparent and very slightly included is uncommon, because many specimens at this weight from the region exhibit stronger inclusion networks. The net result is an emerald that offers the rare combination of size, intense color, and clean eye level appearance, traits that appreciators of fine gemstones understand to materially increase desirability and long term value.

Enhancement is reported as standard, a disclosure that aligns with established trade practice for natural emeralds, and it should be understood by the informed buyer to mean the stone has received routine clarity enhancement to stabilize surface reaching fissures and to improve visual clarity. Standard enhancement typically involves the use of low refractive index oils or resins that remain compatible with mounting and normal wear under prudent care. While enhancement does not detract from the natural origin or beauty of the specimen, it does require that the purchaser adopt standard maintenance precautions, avoiding high heat and harsh solvents, and consulting a professional for any restoration work. The provenance from Zambia is significant, because Zambian emeralds are known for consistent chromium and vanadium chromophores that produce intense greens with a cooler cast, and this example from The Natural Emerald Company is an excellent demonstration of that typology while offering better than typical eye clarity for the weight class. For designers and connoisseurs looking to set the stone, the combination of dimensions, robust color, and excellent polish make it especially suitable for bezel supported solitaire settings, east west mounts, or bespoke pieces where the step facets and emerald cut silhouette will be showcased.

At The Natural Emerald Company we document the attributes of this gem with technical precision and transparency, offering graders and clients the specific dimension set, the one point three five carat weight, the emerald cut style, the declared very slightly included clarity at eye level, the intense color intensity, the excellent polish, the standard enhancement, and the Zambian origin. Our lapidary selection emphasizes well proportioned stones that retain strong face up color and practical durability, and this emerald meets those criteria while representing a rare confluence of size and clarity for material from its origin. For the buyer who seeks a natural emerald that will serve as a long term centerpiece in a fine jewelry setting, this stone offers a compelling technical and aesthetic profile, and our team can provide additional measured photography, viewing under controlled lighting, and handling recommendations to support evaluation and setting. If you require further spectral data, recommended setting geometry, or guidance on conservation and insurance grading, our specialists at The Natural Emerald Company are available to provide targeted technical information and customized service.
