1.90 Ct. Zircon from Ceylon (Sri Lanka)

This 1.90 carat transparent white zircon from Ceylon presented by The Natural Gemstone Company is cut in a classic emerald cut shape, with precise dimensions of 7.82 by 5.58 by 3.68 millimeters. The cutter has respected an elongated rectangular proportion and achieved a length to width ratio of approximately 1.40, yielding a balanced, elegant outline when set in most jewelry silhouettes. The pavilion and crown geometry have been executed as a traditional step cut with elongated facets, a broad table and truncated corners to emphasize internal clarity and architectural light return, while the overall depth measures approximately 55 percent of the averaged face dimensions, a proportion chosen to optimize face up brightness and minimize windowing without compromising the stone s inherent dispersion. Clarity is graded as very slightly included at eye level, color intensity is colorless, and the polish is excellent, indicating tight facet junctions, consistent facet angles, and a high quality lap finish that maximizes light entry and exit from the stone.

Optically this white zircon displays the species specific combination of high refractive index and significant dispersion, which translates into strong brilliance and distinct fire, even within the restrained vocabulary of a step cut. The step facets produce planar flashes that emphasize luster and crystalline transparency rather than the scintillation typical of brilliant cuts, and the absence of enhancement ensures that these optical characteristics are entirely natural. The very slightly included clarity grade reflects minute inclusions that are limited in size and distribution, they do not materially interrupt light transmission or the telltale flashes of spectral color. Excellent polish reduces surface scattering and allows the stone s high birefringence to contribute pleasant internal separation of light without appearing doubled to an untrained eye, while precise symmetry ensures balanced return across the table and along the stepped pavilion facets.

Provenance and craftsmanship are material to connoisseurs, and this specimen s origin from Ceylon Sri Lanka is significant, as the region is known for producing zircons with superior crystal habit and clarity. The Natural Gemstone Company presents this white zircon unenhanced, so collectors and setters receive an untreated natural gem with predictable aging behavior under wear conditions. Technically minded buyers should note that natural zircon has a Mohs hardness approximately in the range of 6 to 7.5 and demonstrates brittle fracture mechanics relative to corundum, therefore protective setting choices are recommended for daily wear applications. A low profile prong setting with sturdy prongs, a partial or full bezel, or a gallery that shields the girdle will help mitigate impact and abrasion, while an open pavilion and minimal bezel will maximize light performance when display is the priority. The cutter s emphasis on proportion and polish makes this piece suitable for high end bespoke settings where precision fit and controlled light pathways are essential.

When set in jewelry the colorless intensity of this zircon offers a versatile palette that interacts distinctly with different skin tones and metal choices, and thoughtful setting design will enhance its visual effect. Against cool undertones and fair complexions the stone reads as icy and crystalline, particularly when mounted in platinum or white gold where the metal's neutral sheen reinforces the stone s colorless clarity and the step facets translate into a refined, luminous presence. On warm to olive complexions the colorless surface provides a crisp, bright contrast that articulates the faceting geometry, and the addition of a warm metal surround in yellow or rose gold can introduce a complementary warmth without masking the zircon s natural fire, a narrow bezel or a mixed metal shank work well to balance the cool sparkle with skin warmth. For deeper skin tones the high transparency and dispersion produce striking highlights and a three dimensional flash that registers strongly at a distance, and setting the stone with high contrast elements such as a white metal halo or polished darkened bezel will amplify the spectral flashes. In all cases the emerald cut s long table emphasizes purity and architectural presence, so choices that allow light to reach the pavilion effectively deliver the most dramatic face up brightness, whereas closed or heavy bezels will protect the stone but trade some optical vigor for durability.
