6.18 Ct. Beryl from Ceylon (Sri Lanka)

This transparent 6.18 carat green beryl presents a rare combination of size and refinement, offering a significant face up presence at dimensions of 13.40 by 10.20 by 7.12 millimeters. The stone is fashioned in a radiant shape, a mixed faceting style that marries the fire of a brilliant cut with the elegant outline of step cutting. Origin is Ceylon, Sri Lanka, a source long respected for producing fine beryl varieties with clean crystallographic development and pleasing tonalities. The material is natural, with no enhancement, and the piece has been evaluated as very slightly included at eye level, a clarity grade that supports a clean, lively appearance while retaining natural character. The color intensity is light, an appealing mint to pale green that performs well under a range of illuminants, and the polish is graded excellent, producing crisp facet junctions and lively surface reflections. This gem is offered and authenticated by The Natural Gemstone Company, ensuring provenance and quality control consistent with discerning collectors and designers.

From a faceting and cutting perspective, the radiant style of this beryl is optimized for both brilliance and table presence. The cutter employed a mixed facet arrangement, combining a brilliant faceted crown with a more angular pavilion, and trimmed corners that reduce the risk of chip damage while adding visual interest. The calibrated proportions yield a depth percent of approximately 60.3 percent, calculated from the recorded depth relative to the stone average dimension, a proportion that balances return of light with apparent size. Facet symmetry is precise, with crown facets meeting the table at uniform angles to produce even scintillation and controlled dispersion. The excellent polish enhances internal light performance by minimizing surface scattering, so that the stone exhibits crisp highlights and deep flashes rather than dulling microabrasion. For settings, the truncated corners and consistent girdle thickness allow for secure four or six prong engagement or a tightly executed bezel, each option preserving the integrity of the pavilion angles that drive its optical performance.

Optically and materially, this beryl demonstrates stable and attractive characteristics that contribute to enduring appeal. The clarity notation, very slightly included at eye level, indicates minor crystal or fluid inclusions that do not dominate the table or create noticeable windowing, while they may serve as natural fingerprints that guarantee origin and authenticity. The light green hue is distributed evenly across the table and crown, avoiding color zoning and allowing the mixed faceting design to refract the subtle green through a balanced spectrum of highlights and body color. Beryl on the Mohs scale rates approximately 7.5 to 8 in hardness, providing notable resistance to everyday wear while still requiring reasonable care to prevent impacts to the corners or abrupt pressure against facet junctions. The absence of enhancement is a critical value factor, as no heat or irradiation treatments have been applied to alter color or clarity, preserving the gem in its natural state. The excellent surface polish and precise cutting geometry will maintain its brilliance over years with routine care.

Over time, the natural beauty of this radiant green beryl will continue to captivate due to its structural soundness, optical equilibrium, and classical proportions. The mint green tone retains relevance across trends, complementing both white and yellow metals and moving seamlessly from modern solitaire designs to more intricate vintage inspired settings. Because the stone is unenhanced and originates from Ceylon, Sri Lanka, collectors can appreciate both its immediate visual appeal and its place within a documented gemological tradition, enhancing its provenance and potential as an heirloom. Routine maintenance is straightforward, warm soapy water and a soft brush will preserve surface luster, and professional inspection of prongs and settings will maintain long term security, particularly for pieces intended for daily wear. The Natural Gemstone Company stands behind the cut, clarity, and origin details provided, and can assist with mounting recommendations that protect the radiant corners and showcase the stone s balanced light return, ensuring that this 6.18 carat green beryl remains a source of admiration and value for decades.
