17.56 Ct. Citrine from Ceylon (Sri Lanka)

One beautiful transparent gemstone presented by The Natural Gemstone Company is a seventeen point five six carat citrine, fashioned into a trillion shape with generous proportions, measuring approximately seventeen point four nine by seventeen point four six by eleven point four six millimeters. The stone displays a yellowish brown hue with intense color intensity, and it has been cut in a mixed brilliant style to maximize both color depth and light performance. The overall presentation is of a single large, eye catching center stone, with an excellent polish that produces crisp facet junctions and clean reflections across the table and crown. This is a hand selected example that combines substantial weight and broad face up area with excellent symmetry, making it an ideal candidate for a dramatic solitaire ring or a bespoke pendant where the color and brilliance can be showcased without distraction.

From a gemological perspective this citrine warrants attention for a number of reasons that matter to an educated buyer. Its clarity grade is very very slightly included, evaluated at eye level, which indicates that the stone is essentially eye clean and that any natural inclusions are minimal in size and position, having no appreciable impact on transparency or light transmission. The combination of intense color and high transparency is relatively uncommon in stones of this size, and because this particular example is reported as having no enhancement, it represents a naturally colored material from Ceylon, Sri Lanka, a classic provenance for quality quartz varieties. The excellent polish and precise mixed brilliant faceting contribute to strong light return and scintillation, while the durable nature of quartz with a Mohs hardness of seven means it is suitable for many types of jewelry with appropriate care. For collectors who prioritize natural origin, untreated material, and strong visual presence, this citrine is a compelling proposition, offering clarity, color, and size in a single attractive package.

The visual performance of this citrine is driven by both its internal crystal structure and the cutter s decisions, creating a sparkle that is unmatched by many other gemstones in its class. Citrine is a variety of quartz that crystallizes in the trigonal system, and its uniform internal lattice provides excellent transparency when free from significant inclusions. The refractive index values typical for quartz enable effective light refraction across well executed facets, and when combined with a mixed brilliant cut, the result is a balance of brilliance and fire that is particularly lively. The mixed brilliant design uses a combination of brilliant style facets on the crown to produce strong white light return and scintillation, with a pavilion arrangement that channels light back through the table in lively flashes. The trillion shape further enhances this effect by offering broad facet planes that catch and break light into dynamic reflections, and the generous depth of this stone allows facets to interact at optimal angles, producing a three dimensional sparkle that changes as the stone moves. Excellent polish ensures that light scatters cleanly rather than being diffused by surface abrasion, so highlights remain sharp and contrasty, enhancing the perception of depth and internal luster.

For a discerning buyer The Natural Gemstone Company presents this citrine as a rare combination of provenance, untouched natural color, substantial carat weight, and precision cutting, all of which increase its desirability and potential for long term satisfaction. The intense yellowish brown tone is versatile enough to complement both warm and neutral metal settings, and the overall proportions make it well suited to bespoke mounting where the stone s optical performance can be maximized. When selecting a setting, consider designs that allow light to enter from multiple angles to fully exploit the mixed brilliant cutting, and choose protective bezel or partial bezel designs in high wear pieces to preserve the excellent polish and facet integrity. This citrine will appeal to collectors, designers, and clients seeking a statement center stone with verifiable natural origin and superior optical qualities, and it is offered with the confidence that its structural and cutting attributes deliver a sparkle and presence that stand out among comparable gemstones.
