16.44 Ct. Sky Blue Topaz from Brazil

One beautiful transparent 16.44 carat oval sky blue topaz, measuring 16.28 x 12.81 x 9.58 millimeters, presents a compelling combination of scale, color, and cut. The gem is fashioned in a mixed brilliant cut, a design that combines brilliant-style facets with larger pavilion facets to maximize sparkle and maintain a graceful oval outline. The stone exhibits intense color intensity and an excellent polish, attributes that together produce strong light return and a lively, saturated sky blue appearance. Clarity is reported as very slightly included, evaluated at eye level, which means only minor inclusions are apparent on close inspection and do not materially detract from transparency or brilliance. Enhancement by irradiation has been applied, a widely practiced and stable treatment in the trade to produce or intensify blue tones in topaz, and this treatment is fully disclosed. These technical specifications, verified and presented by The Natural Gemstone Company, are important for an educated buyer assessing optical performance, durability, and value.

The Brazilian origin of this topaz adds meaningful provenance value, because Brazil, and particularly historic districts such as Minas Gerais, is renowned for producing large, clean crystals and gems with attractive blue tones. Provenance from Brazil often commands a premium among collectors and connoisseurs because it speaks to consistent geological conditions that yield larger, higher clarity material compared with many other sources. For the discerning buyer, the primary determinants of market value are the substantial carat weight of 16.44 carats, the intense and even sky blue color, the high quality mixed brilliant cut and polish, the clarity grading, and the transparent disclosure of irradiation. Treated blue topaz is widely accepted, energetically stable, and offers excellent value relative to extremely rare, naturally colored blue topaz varieties, while the combination of size and eye-clean appearance elevates this specimen into a category of collector quality. The Natural Gemstone Company stands behind full disclosure and can assist with certification options, recommended mounting styles for showing off the oval mixed brilliant cut, and guidance on appraisal and insurance, ensuring that this Brazilian sky blue topaz is presented and valued appropriately for both jewelry and investment purposes.
