12.83 Ct. Greenish Yellow Citrine from Ceylon (Sri Lanka)

This 12.83 carat oval greenish yellow citrine from Ceylon embodies a technical clarity and cutting precision that appeals to discerning collectors and makers, presented to you by The Natural Gemstone Company. The stone measures 18.20 x 13.29 x 9.11 mm, yielding a length to width ratio of 1.37, which sits comfortably within the proportion range favored for classic oval profiles. The cutter executed a mixed brilliant scheme, combining a well defined brilliant crown with angular star and kite facets, and a faceted pavilion designed to maximize return and scintillation. The crown and table relationships are balanced to avoid windowing, while the pavilion facets exhibit consistent angles that create lively light return across the table and along the length of the gem. The clarity was graded eye clean at eye level, confirming the absence of visually significant inclusions that could interrupt light paths or compromise setting security. Color evaluation indicates an intense color intensity, a greenish yellow hue with even saturation and a medium to medium deep tone that reads vibrantly in both daylight and artificial light, and the piece is described as having excellent polish, with facet junctions appearing crisp and facet planes smooth, signatures of meticulous lapidary finishing. Importantly this citrine has no enhancement, carrying stable natural color from its Sri Lankan origin, and its crystalline structure as quartz offers a hardness of 7 on the Mohs scale and low cleavage, attributes that support both aesthetic longevity and practical wearability.

For the jeweler and client focused on craft, this citrine is optimized for bespoke settings that respect its pavilion depth and maximize its presence. The substantial depth of 9.11 mm requires a setting with sufficient gallery clearance and a bezel or prong structure that seats the pavilion without impeding light entry through the crown. A minimum of four evenly spaced prongs with tapered shoulders will protect the girdle while allowing light play, while a custom full bezel can provide added security for everyday wear without sacrificing the stone appearance if the bezel is slotted to permit light from the sides. Metal choices will influence perceived color. Warm 18 karat yellow gold will enhance the golden green tones and create a harmonious overall presentation, while platinum or white gold provides a crisp contrast that emphasizes spire like internal reflections and the precision of the cut facets. Consider complementary design elements such as a diamond halo to increase perceived fire, or a low profile gallery and pierced underbeading to allow a play of light that interacts with the mixed brilliant pavilion. For a ring intended to be a statement piece, the oval’s length oriented vertically will visually elongate the finger, and the 12.83 carat weight ensures a presence that reads both luxurious and architecturally coherent in proportion to a well engineered mounting.

As an heirloom candidate this citrine meets the technical criteria for long term retention of value and beauty, and The Natural Gemstone Company supports its handover through documentation and recommended maintenance protocols. The quartz structure and untreated color mean that with normal care the hue will remain stable for generations, provided the gem is not subjected to prolonged extreme heat or abrasive chemicals. Routine inspection of the setting every six to twelve months is advisable, with prong re tipping and secure gallery checks to prevent loss through mechanical wear. Professional cleaning with warm soapy water and a soft brush is appropriate, and ultrasonic cleaning is acceptable only after confirming the integrity of the setting and absence of internal fractures. We recommend accompanied provenance documentation identifying origin as Ceylon, and a gemological report to certify the untreated status, clarity, and cut proportions, materials that enhance resale and inheritance value. When integrated into a thoughtfully engineered mounting, regularly serviced, and accompanied by certification and insurance, this 12.83 carat Ceylon citrine becomes a durable, technically sound emblem of legacy, ready to be passed down within a family with the provenance and support provided by The Natural Gemstone Company.
