This listing describes a single translucent white topaz weighing 3.23 carats, presented in an oval outline with precise dimensions of 9.94 by 8.10 by 5.13 millimeters, originating from Ceylon, Sri Lanka, and supplied by The Natural Gemstone Company. The stone has been faceted as a mixed brilliant cut, combining a brilliant facet pattern on the crown with controlled pavilion faceting to maximize scintillation and light return in a near colorless material. The clarity has been evaluated as eye clean at normal viewing distance, with no inclusions visible to the unaided eye, and the finish shows an excellent polish that produces crisp facet junctions and minimal surface disturbance. Enhancement by irradiation has been applied to stabilize and refine the stone toward a near colorless presentation, a standard treatment for topaz that creates stable color centers without affecting the macroscopic clarity, and the overall presentation is one of high optical purity and ready compatibility with fine jewelry settings.
The cutting style is deliberately engineered, the crown follows a traditional brilliant motif to create a dense field of small, kite and star shaped facets that break incident light into numerous reflections, while the pavilion employs a modified step approach to control the pathway of light through the body and prevent windowing in the center. Facet proportions are closely balanced to the oval outline, with measured crown angles and pavilion depths that preserve total depth near 5.13 millimeters, resulting in an economical distribution of weight without sacrificing face up size. The oval symmetry and girdle profile support stable practical mountings, and the excellent polish ensures each facet plane acts as a precise mirror, enhancing the mixed cut interaction so flash and scintillation behave predictably under varied light sources. This combination of cutting strategy and finish reflects a cutter intent on maximizing brilliance and durability for a near colorless topaz from Sri Lanka.
Although the gem appears eye clean, microscopic examination reveals a characteristic set of internal features that together supply an unmistakable signature for this particular specimen. Linear growth tubes and hairline growth zoning occur in oriented arrays consistent with topaz formation under the geologic conditions typical of Ceylon deposits, these fine linear inclusions are commonly parallel to the crystallographic axis and under magnification produce subtle light diffraction that softens larger facet reflections, contributing a living, satin like quality to the center of the stone. Minute two phase inclusions, composed of a tiny trapped fluid meniscus with an associated vapor bubble, appear in isolated pockets, and healed fissures show as narrow, lamellar planes with sericitic halos, these healed planes are reflected in the way light redistributes across the pavilion, creating a unique flash pattern when the gem is tilted. A sparse distribution of microscopic pinpoint crystals and faint particulate clouds further modifies light scattering at high magnification, these elements remain below the threshold for unaided visibility yet they provide an identification fingerprint that trained graders and experienced cutters can use to confirm origin and treatment history.
When considering pairing or comparison, it is useful to contrast this white topaz with a White Opal, the opal type known for a diffuse white body tone often exhibiting play of color due to the ordered silica sphere structure, this topaz instead offers a near colorless body with structured internal reflectors and a signature tied to growth tubes and micro inclusions rather than opaline diffraction. For setting recommendations, the stone is well suited as a solitary center in a fine prong setting or as the focal point in a halo arrangement where the mixed brilliant cut enhances surrounding accent stones, the eye clean clarity and excellent polish ensure the stone will read as clean and bright in hand, while the microscopic inclusion suite will continue to provide a diagnostic identity under loupe or microscope. The Natural Gemstone Company presents this Ceylon white topaz as a technically refined specimen, ideal for collectors and experienced jewelers who appreciate the interplay of cut geometry, controlled enhancement, and the subtle natural inclusions that combine to give the gem its unmistakable signature.
