3.66 Ct. Precious Topaz from Brazil

This pear shaped, transparent precious topaz from Brazil weighs 3.66 carats, with calibrated dimensions of 14.95 by 8.02 by 4.43 millimeters, and a length to width ratio of approximately 1.86, which produces an elegant elongated drop suitable for both solitaire settings and asymmetric design work. The gem has been fashioned in a mixed brilliant cut, a faceting style that combines a brilliant crown with a modified pavilion, and this particular cutting regimen has been executed to emphasize internal light return and scintillation while preserving outline integrity. Color is described as orangish yellow with a medium intense saturation, and clarity has been assessed as very slightly included at eye level, indicating minimal internal characteristics that do not compromise transparency or durability. The surface finish is graded as excellent polish, and the gem has undergone standard heat treatment to stabilize and enhance its hue, a widely accepted and stable enhancement practice for topaz. The provenance is Brazil, a source noted for producing gem quality topaz crystals with good clarity and balanced color, and The Natural Gemstone Company provides full disclosure of origin and treatment to support informed purchasing decisions.

From a cutting and gemological perspective, the mixed brilliant execution on this pear shape is technically purposeful, the crown facets are arranged to create strong table and crown light return, while the pavilion facets are calibrated to a modified brilliant schema that reduces light leakage toward the tip of the pear. The cutter has maintained careful symmetry between the two lobes and the tapered point, keeping facet junctions crisp and alignment consistent, which minimizes the common pear shape pitfalls of uneven light distribution and excessive bow tie effect. The shallow to moderate total depth as supplied yields an appearance that favors face up spread, which maximizes the apparent size for the carat weight while maintaining lively scintillation. Faceting precision and the excellent polish together create clean facet windows, sharp facet girdle junctions, and predictable replay of fire and brilliance under viewing conditions, attributes that experienced setters and designers rely upon when planning prong counts and pavilion access for light engineering.

Clarity and color behavior of this topaz merit technical attention for buyers who assess optical performance. The very slightly included grade, evaluated at eye level, denotes inclusions that are small in size and limited in number, and these features often act as internal fingerprint markers that confirm natural growth rather than synthetic origin. These inclusions do not materially interfere with the stone’s transparency, and under standard lighting the mixed faceting disperses light across the orangish yellow body color producing even saturation with localized flashes of lighter yellow highlights. The medium intense color suggests a balance between tone and saturation that reads well in both white and yellow metal mounts, and because topaz is a hard gemstone with a Mohs rating of eight, this specimen combines resilience with optical appeal. Gemological properties such as refractive index, which for topaz broadly ranges near 1.609 to 1.643, and modest dispersion contribute to a clean, lively appearance rather than excessive spectral breakup, which is consistent with the mixed brilliant approach used by the cutter.

When comparing this natural Brazilian topaz to lab grown gemstones, several technical and market advantages become apparent. Natural topaz exhibits growth features and trace element signatures that impart subtle complexity to color, often resulting in variegation and pleochroic tendencies that are difficult to reproduce uniformly in synthetic material. Provenance and natural inclusion patterns function as verifiable indicators of origin and geological history, factors that materially affect long term collector value and resale potential, aspects where natural stones traditionally outperform synthetics. Heat treatment applied to topaz is an established, stable enhancement with predictable outcomes, and disclosure of this treatment preserves market transparency, whereas some synthetic products require repeated or more invasive post growth processing to approximate natural color characteristics. In terms of craftsmanship appreciation, the slight variability in facet response and internal light routing in a natural stone is often preferred by connoisseurs who value singularity over the uniformity of lab grown material. For purchasers seeking a combination of technical excellence and natural provenance, this 3.66 carat pear shape orangish yellow topaz offered by The Natural Gemstone Company represents a documented, well cut, and attractively colored natural specimen that integrates gemological integrity, durable physical properties, and artisanal faceting for use in high quality jewelry settings.
