3.00 Ct. Topaz from Ceylon (Sri Lanka)

This transparent round blue topaz weighs three point zero zero carats and measures eight point two zero by eight point three three by six point zero three millimeters, a compact but visually significant size for a round gem. The cutting style is mixed brilliant, combining a full brilliant crown with a modified pavilion that produces both surface sparkle and internal contrast. Clarity is graded as very very slightly included at eye level, which means the stone appears eye clean with only minute inclusions detectable under magnification, allowing maximum light transmission through the material. Color is classified as medium light intensity, an airy sky blue tone achieved and stabilized by irradiation, a standard and permanent enhancement for blue topaz, and the stone is of Ceylon origin, sourced from Sri Lanka. The polish is excellent, with smooth facet planes and crisp facet junctions, and the overall finish reflects the precise lapidary work that clients expect from The Natural Gemstone Company.

On close examination the mixed brilliant faceting shows disciplined facet geometry, with a small to medium table that preserves a strong crown to pavilion balance. The crown facets are cut to capture incident light and break it into scintillation, while the pavilion features additional facets arranged to optimize internal reflection angles for topaz, a gemstone with a refractive index in the range of one point six zero nine to one point six four three. The measured depth of six point zero three millimeters compared to an average diameter of approximately eight point two six millimeters produces a depth ratio near seventy three percent, which is intentionally deeper than many standard round brilliants in order to increase optical return for this particular material. That deeper pavilion geometry, combined with precise symmetry and well executed facet junctions, creates the clear star pattern visible through the table and enhances contrast between bright flashes and darker facets, producing lively scintillation rather than diffuse washout. The excellent polish and tight girdle control contribute to a clean vitreous surface luster, and the eye clean clarity amplifies the sensation of depth, giving the apparent hue a crisp and saturated appearance for its medium light classification.

When comparing brilliance and overall visual performance to more common blue gemstones, the optical profile of topaz positions it uniquely. Topaz has a higher refractive index than beryl varieties such as aquamarine, which typically yields a brighter, more refractive response under the same facet design, while dispersion or fire for topaz at approximately zero point zero one four is slightly greater than beryl but markedly lower than zircon and diamond. This means that unlike blue zircon which produces intense multicolored fire but can appear visually noisy and can be brittle, this blue topaz offers controlled scintillation with a clean, cool flash rather than overt spectral dispersion. Compared to blue sapphire, which has a higher refractive index and stronger saturation potential, this medium light Ceylon topaz reads as lighter and more luminous in daylight situations, offering an airy brilliance and quick scintillation that can appear more lively in shallow settings. The topaz also benefits from greater hardness and toughness than many high dispersion alternatives, making it well suited for ring settings intended for regular wear, and the irradiation enhancement used here is stable and industry accepted, producing a dependable and even tone without compromising clarity or surface quality.

For the connoisseur seeking a balance of technical precision and everyday practicality, this three carat Ceylon blue topaz represents a compelling choice. The mixed brilliant cut is executed to extract maximal optical performance from the material, the eye level clarity preserves transparency and contrast, and the medium light blue achieved through controlled irradiation delivers a consistent hue across viewing angles. The craftsmanship demonstrated in the facet symmetry, pavilion depth, and excellent polish results in a gem that presents bright, well controlled brilliance without excessive fire, and that visual character distinguishes it from more common blue gemstones while offering robust wearability. This stone is offered through The Natural Gemstone Company, where we emphasize documented origin, transparent disclosure of treatments, and meticulous cutting standards to ensure that each gem meets the expectations of technical collectors and discerning jewelry designers.
