7.76 Ct. Yellow Citrine from Ceylon (Sri Lanka)

This oval shaped citrine presents as a precisely measured 7.76 carat gemstone, with finished dimensions of 14.81 by 11.31 by 7.58 millimeters. The cutter has executed a mixed brilliant strategy, combining a well proportioned brilliant style crown with calibrated pavilion faceting to maximize light return while preserving face up color. The proportions yield a depth of approximately 58 percent relative to the average of length and width, a dimensional balance that offers both satisfying presence and efficient internal reflection. The crown displays crisp facet junctions and an excellent polish, which enhance surface luster and contribute to crisp facet separation. The overall silhouette is true to an elongated oval, enabling versatile mounting options and an attractive table presentation when set.

Optically this specimen exhibits a medium intensity yellow hue, evenly distributed across the table and pavilion, with a transparency that reads as transparent to the unaided eye. Clarity has been assessed as very very slightly included when evaluated at eye level, meaning inclusions are minimal, minute in scale, and do not detract from the overall visual performance in typical jewelry settings. The gem is unenhanced, the color and clarity reflecting natural formation without heat or irradiation treatment, and it is documented as originating from Ceylon Sri Lanka. As a quartz species, citrine has a refractive index in the range of approximately 1.544 to 1.553 and a low birefringence near 0.009, parameters that yield crisp facet contrast and stable optical behavior under varied lighting. Specific gravity is near 2.65, which confers good heft for its size and a satisfying tactile presence in hand made settings.

From a durability and suitability perspective this citrine is well adapted to daily wear. Quartz has a Mohs hardness of seven, which provides robust resistance to everyday abrasion compared with many softer gem materials. The crystal structure of quartz lacks true cleavage, so the stone does not split along preferential planes in the way that cleavable gems can, and fracture behavior is conchoidal rather than sheet like, which improves practical toughness during routine use. The excellent polish and the controlled facet angles applied by the cutter reduce the likelihood of microabrasion marks appearing quickly, and the very very slight inclusions present are neither structural deficiencies nor weak planes that would compromise setting integrity under normal wear. For high impact activities or occupations involving repeated knocks, we recommend protective bezel or partial bezel settings, while well executed prong settings using secure four or six prong architectures will also perform well when the wearer observes normal care.

Care and maintenance are straightforward and consistent with best practice for quartz gemstones. Clean with warm soapy water and a soft brush to maintain the polish and remove surface oils and residues. Steam cleaning and ultrasonic cleaning are generally acceptable for solid, unfilled quartz, however these methods should be applied with caution if the stone is already mounted with delicate metals or assembled components, or if other nearby materials in the finished jewelry could be sensitive to thermal or vibrational stress. Avoid exposure to strong acids, prolonged contact with chlorine based cleaners, and sustained high temperature excursions, as these conditions can affect metal settings and in extreme cases alter surface appearance. When selecting a setting for daily wear, consider protective gallery work and sufficiently tall prongs so that the girdle is not the primary contact point during wear, this approach minimizes the potential for edge nicks and preserves the faceted symmetry over years of use.

This citrine from The Natural Gemstone Company represents a convergence of natural material quality and considered lapidary execution. The mixed brilliant faceting yields an appealing balance of brilliance and color saturation, while the medium yellow tone is versatile for both warm tone and neutral metal palettes. At 7.76 carats and with dimensions that sit comfortably as a statement ring or a focal pendant, the gem lends itself to bespoke settings where the cutter retained weight and optimized face up color. Our gemological team inspects and documents key parameters including weight, dimensions, cut style, clarity observations, and origin, and we provide guidance on setting and care to preserve performance. For clients seeking a durable, eye catching colored stone that performs reliably in daily wear, this Ceylon citrine offers a technically sound and visually pleasing choice.
