1.06 Ct. Green Zircon from Ceylon (Sri Lanka)

This natural green zircon is a precisely measured and finely finished gemstone, weighing 1.06 carat and presenting an elongated oval outline with dimensions of 7.19 by 4.76 by 3.67 millimeters. It is executed in a mixed brilliant cut that combines a faceted brilliant crown with a calibrated pavilion composed of modified step facets, a combination chosen to maximize both internal light return and controlled fire. The overall depth of the stone, calculated against the mean of the length and width, is approximately 61.4 percent, a proportion that yields brisk scintillation without sacrificing table brightness. Origin is Ceylon Sri Lanka, and the specimen is unenhanced, exhibiting its natural chroma and tone as extracted from the deposit. The polish quality is excellent, with facet junctions that display crisp facet meet lines and minimal surface abrasion, a detail that contributes directly to the gemstone s apparent luster and contrast when set.

Cutting details are central to the optical personality of this piece. The mixed brilliant crown deploys a combination of star, bezel, and upper girdle facets arranged to create a balanced pattern of light and dark areas that animate under movement, while the pavilion s modified steps act to collimate light and reinforce the gem s dispersion. Zircon s inherently high refractive index and notable dispersion produce an adamantine luster and lively flashes of spectral color, and the cutter has taken advantage of this by restraining an oversize table and by maintaining symmetric pavilion angles to avoid light leakage. The stone also displays measurable birefringence, which can cause faint doubling of facet edges when viewed at certain orientations, a diagnostic property of zircon that enhances the perception of depth and internal texture. Clarity is graded as slightly included at eye level, meaning that inclusions are present but confined to small pinpoint or thin needle like features that do not materially interfere with the gem s overall transparency or light performance, and the internal features can add character without undermining structural integrity.

Color attributes are among the most compelling aspects of this gem. The hue is a true green with an intense saturation and medium to medium dark tone, a combination that allows the stone to read as rich and verdant without leaning toward over darkening that would mute brilliance. Under neutral daylight the green appears pure and deep, while under warmer incandescent lighting the gem shows a subtly warmer green, a modest shift that speaks to its natural chromophores and pleochroic tendencies. As the material is unheated and unenhanced, the color is stable under normal wear conditions, and the provenance from Ceylon ties it to a long lineage of high quality material from Sri Lankan pegmatitic and alluvial sources. Historically, green zircon from the region has been used in traditional signet and devotional jewelry and was frequently cited in 18th and 19th century gemological inventories as a stone prized for its brilliance and clarity, a heritage that this example directly inherits. Collectors who value traceable origin and unaltered material will appreciate both the gem s natural state and the historical continuity that The Natural Gemstone Company provides through careful sourcing.

For practical use and long term care, this zircon is best appreciated in settings that protect the girdle and crown facets while allowing light to enter the table freely. A bezel or low profile four prong mounting with a supportive under gallery will minimize exposure to knocks and reduce the risk of facet chipping, acknowledging that zircon s hardness, while sufficient for most jewelry, is less resistant to abrasion than corundum or diamond. Clean the stone with warm soapy water and a soft brush, and avoid prolonged exposure to heat sources, steam, or aggressive ultrasonic cleaning which can alter color and potentially damage natural inclusions. We at The Natural Gemstone Company stand behind the natural, unenhanced origin of this 1.06 carat green zircon, and we supply full technical provenance and condition information to informed buyers who require clear, verifiable data for appraisal or bespoke design work. This gem offers a rare confluence of intense natural color, considered cutting, and historical resonance, making it an excellent candidate for a refined ring or a signature pendant where technical quality and cultural narrative are both valued.
