17.56 Ct. Citrine from Ceylon (Sri Lanka)

One beautiful transparent 17.56 carat trillion shape orangish yellow citrine awaits collectors and designers who demand exceptional natural gemstones, The Natural Gemstone Company presents this remarkable gem with dimensions of 17.49 x 17.46 x 11.46 mm, a precise trillion cut that balances bold presence with elegant geometry. The stone is graded as very very slightly included at eye level, which means that under casual inspection the surface appears crisply clean, while a trained eye may note only the most minor internal features that do nothing to detract from the gem overall beauty. Its color intensity is described as intense, a warm orangish yellow saturation that reads vivid and alive under natural light. There has been no enhancement, this citrine is natural, and its origin is Ceylon Sri Lanka, a source known for producing gemstones with fine color and clarity. The polish on this gem is excellent, a mirror like finish that allows each facet to act as a precise plane for light to enter and exit, producing that immediate sense of life and movement that separates a fine gem from a merely pretty one.

The unique sparkle of this citrine is the result of two cooperating factors, the intrinsic crystal structure of quartz and the expert execution of the trillion cut. Citrine is a variety of quartz with a trigonal crystal system, and quartz has a refractive index of approximately 1.54 to 1.55, which governs how light bends as it enters and leaves the gem. While quartz does not display the high dispersion of gemstones like diamond, the combination of excellent transparency, minimal inclusions, and the precise angle placement of a well executed trillion cut yields exceptional light return and scintillation. The trillion cut concentrates multiple small facets across a bold triangular silhouette, creating a lattice of reflective planes that capture ambient light from many directions. As light travels into the stone it meets these planes, and because the cutter has respected ideal proportions and symmetry, light is efficiently reflected back toward the eye rather than lost through the pavilion. The result is a gemstone that seems to sparkle from within, a lively interplay of bright flashes and larger areas of warm color that make this citrine feel brighter and more animated than many stones of similar type on the market.

Compared to other citrines commonly available, this Ceylon gem stands out for its combination of size, natural color, and clarity without enhancement. Many citrines on the market are moderately colored or have been heat treated to achieve deeper hues, and while heat treatment can produce attractive tones, nothing replaces a naturally occurring, evenly distributed intense color. In this gem the orangish yellow saturation is not concentrated in one area, it bathes the entire stone evenly, which enhances both perceived size and light performance. Compared to glass or synthetic substitutes, the refractive response and the way reflections break across the trillion facets are unmistakably natural and lively. When placed against higher dispersion stones like topaz or sapphire, this citrine holds its own by offering warm, sunlit color and a kind of dynamic brightness that is proportionate to its generous 17.56 carat mass. Value wise, gemstones of this quality and size with no enhancement from a reputable origin are rare, making this citrine not only a visual pleasure but a shrewd acquisition for someone who values authenticity, aesthetic impact, and lasting beauty.

For jewelers and buyers deciding on the best setting to highlight this stone, the trillion shape facilitates bold contemporary designs as well as vintage inspired compositions that place the gem at center stage. A well designed setting that allows light to penetrate the pavilion will further amplify the intrinsic sparkle, by letting the many facet planes do their work without being muted by metal. The excellent polish ensures that each facet edge reads crisp and controllable, so prong or bezel settings can be chosen for aesthetics and security without sacrificing brilliance. In practical terms this citrine has the hardiness of quartz, meaning it is suitable for daily wear when set with reasonable care, and its size makes it an ideal choice for an impactful solitaire ring, an eye catching pendant, or an elegant cocktail piece. By choosing this gemstone through The Natural Gemstone Company, buyers gain not only a striking orangish yellow citrine with a radiant trillion cut, but also the assurance of provenance, clarity, and polish that together create a sparkle and presence few comparable stones can match. If you are seeking a gem that balances striking appearance, natural authenticity, and sound value, this 17.56 carat Ceylon citrine offers a rare combination that will command attention and admiration for years to come.
