1.63 Ct. Topaz from Brazil

This 1.63 carat oval sky blue topaz from Brazil is a fine example of balanced gemmological attributes, offered by The Natural Gemstone Company, and tailored for the informed buyer who values accurate grading and provenance. The stone measures 8.13 by 6.13 by 4.49 mm, and presents a transparent body with medium color intensity that is evenly distributed across the table and crown. It has been fashioned with a mixed brilliant cut, combining a faceted crown designed for optimal light entry with a carefully proportioned pavilion that returns light with strong brilliance. The clarity is graded as very very slightly included when evaluated at eye level, a practical and desirable clarity category that means inclusions are minimal and do not detract from visual performance in standard jewelry settings. The gem displays an excellent polish, a finish that enhances surface reflection and overall sparkle, and it has been enhanced by irradiation to achieve its stable sky blue hue, a common and well understood treatment for topaz sourced from Brazil.

The geometric faceting of this topaz is intentionally designed to allow maximum light play, and the mixed brilliant configuration plays a central role in that performance. The crown facets are cut to precise angles that promote entry of white light into the stone, while the pavilion facets are arranged to facilitate efficient internal reflection and return of light toward the viewer. This interplay produces strong brilliance, controlled scintillation, and subtle flashes of spectral color when the gem is viewed under changing light conditions. The oval outline further contributes to perceived size and light dispersion, elongating the visual field so that the stone appears lively from every angle. For collectors and designers, the alignment and symmetry of the facets are as important as the cutting style, and this piece benefits from proportional facet junctions and a polished girdle that minimize light leakage and maximize the visual impact in a mounted piece.

Clarity and color considerations are key to understanding value, and this topaz balances both attributes for measured appeal. The very very slightly included grade indicates that inclusions, when present, are small and typically visible only under magnification or after close inspection at eye level, without materially affecting durability or the gem becoming a weak point under normal wear. Color intensity is medium, which for blue topaz is often preferred because it provides a pleasing saturation while retaining brightness and versatility in design. The excellent polish amplifies both color and clarity, allowing clean light transmission and crisp facet reflections. For the educated buyer considering resale or bespoke mounting, this combination of clarity, color, and polish means the stone will set well in a variety of metals and settings, from solitaire rings that emphasize brilliance to halo or cluster designs that play with contrast and accent stones.

Origin and treatment information are important for long term appreciation and care, and this topaz is identified as originating from Brazil, a region renowned for producing clean and well crystallized topaz material. Irradiation is the enhancement used to produce the stabilized sky blue color, a commonly accepted and permanent treatment when properly followed by heat and controlled processing. This treatment does not compromise the structural integrity of the crystal, and when disclosed, it allows buyers to make informed comparisons across the market. At The Natural Gemstone Company we emphasize full disclosure and provide detailed measurements, grading observations, and handling guidance so that the gem performs beautifully in everyday wear. Whether you are a jeweler, a collector, or a connoisseur seeking a reliably graded Brazilian topaz with excellent polish and thoughtfully executed facets, this 1.63 carat oval sky blue topaz offers a combination of technical quality and visual charm that rewards careful appraisal and considered design.
