1.01 Ct. Beryl from Nigeria

This 1.01 carat green beryl from Nigeria is presented in a classical emerald cut, with precise dimensions of 7.25 by 4.98 by 3.64 millimeters, reflecting a length to width ratio of approximately 1.46, and a depth that measures approximately 59.6 percent relative to the average of length and width. The faceting strategy follows traditional step cut principles, with broad parallel facets on the crown and pavilion that promote a linear light return and emphasize the stone s crystalline transparency. The table facet is proportioned to balance brightness and contrast, while the trimmed corners preserve the characteristic emerald silhouette and improve durability at the setting interface. Clarity is graded as very very slightly included, evaluated at eye level, which in practical terms means the stone is effectively eye clean with only minute internal features detectable under magnification. Color is described as faint in intensity, presenting a delicate cool green hue that interacts with the step facet architecture to yield subtle flashes of tone along the long facets rather than overt color saturation. The polish is excellent, resulting in crisp facet junctions and high surface luster, and importantly the stone is natural with no enhancements, a provenance detail that we at The Natural Gemstone Company prioritize and document for discerning clients.

The geological history of this green beryl spans tens of millions of years, originating deep within silica rich pegmatitic systems where beryllium becomes concentrated through fractional crystallization of a granitic melt. As the parent magma evolved, volatile rich residual fluids enriched in beryllium, aluminium, and trace transition elements exsolved into fractures and cavities, providing the chemical environment necessary for beryl crystallization. Trace iron present in those fluids acted as the primary chromophore in this specimen, yielding the faint green coloration as iron was incorporated into the beryl lattice during slow growth at elevated temperature and pressure. Growth proceeded in discrete episodes, producing elongated prismatic crystals with fine growth zoning and microscopic inclusions that record changes in fluid composition and temperature, effectively preserving a microgeological archive of the pegmatite s cooling history. Over subsequent geologic time scales, regional uplift and erosion liberated these beryl crystals from their primary hosts, transporting them through fluvial systems into secondary alluvial deposits where they were ultimately recovered. The combination of slow, steady crystal growth and minimal later metamorphic overprint is consistent with the stone s high transparency and the very very slightly included clarity we observe today.

The cutting and finishing of this emerald cut green beryl were executed to respect both the stone s natural character and the requirements of precision gemstone craftsmanship. During preforming the cutter oriented the crystal s long axis to align with the principal growth direction, a decision that reduces the risk of parting and preserves carat weight while taking full advantage of the prismatic habit to produce clean step facets. The selected proportions produce a measured interplay between table size and step facet width that maximizes internal light return for a stone of faint color intensity, allowing the subtle green to read consistently in mixed lighting conditions without becoming washed out. The excellent polish and careful symmetry enhance facet contrast and create a refined hall of mirrors effect that is particularly desirable in step cut stones, where facet planes define the gem s visual appeal more than scintillation. With a hardness around seven point five to eight on the Mohs scale, beryl offers reliable wearability, and this piece is ideally suited for settings that expose the pavilion to light while protecting the corners, such as four prong corner settings, a bezel with open gallery, or a low profile solitaire with a secure cup.
