17.13 Ct. Swiss Blue Topaz from Brazil

This beautiful transparent 17.13 carat heart shape Swiss blue topaz from Brazil presents an exceptional combination of size, symmetry, and optical quality, making it an outstanding choice for custom jewelry. Measuring 16.28 by 16.21 by 9.70 millimeters, the stone carries a faceted fancy cut that maximizes light return and scintillation, and its intense color intensity is immediately apparent to the eye. Clarity is graded as eye clean, evaluated at eye level, which means no inclusions are visible without magnification, a highly desirable trait in a stone of this scale. The excellent polish amplifies the gem's brilliance and satiny surfaces, while the heart shape is executed with pleasing symmetry, offering a true focal point for bespoke designs. The color has been developed by irradiation, a common and controlled enhancement for blue topaz, and when properly processed this treatment yields a stable, long lasting Swiss blue hue. Origin from Brazil underscores the gemological credibility of the piece, as Brazilian topaz is renowned for its clean crystals and quality cutting material.

For the custom jeweler and the discerning buyer, this heart shape topaz is ideal as a center stone for a statement pendant, a romantic solitaire or halo engagement ring, or a luxurious cocktail ring, because its generous carat weight and broad table allow for dramatic presence without overwhelming the setting. The heart silhouette lends itself to intimate, emotive designs, while the faceted fancy cut ensures lively play of light that pairs beautifully with accent diamonds or colored gemstone halos. Practical considerations for setting are straightforward, given topaz hardness and cleavage characteristics, so protective design choices such as a secure prong basket for the lobes and reinforced bezel or bezel rim for the pointed tip will safeguard the stone during wear. At The Natural Gemstone Company we provide detailed information on grading, origin, and enhancements, and we can advise on mounting styles that balance aesthetics with protection. This Swiss blue heart topaz, with its rare combination of size, eye clean clarity, intense color, and expert polish, represents a compelling option for anyone commissioning a bespoke piece that demands both beauty and gemological integrity.
