1.78 Ct. Sky Blue Topaz from Brazil

This 1.78 carat oval sky blue topaz from Brazil combines precise proportions and refined faceting to deliver exceptional cut and brilliance, making it a ready centerpiece for any collection. The gem measures 8.06 x 6.16 x 4.46 mm, with an approximate depth of 63 percent, a proportion that balances a generous face up area with strong light return. The mixed brilliant cut integrates a brilliant style crown with a complementary pavilion design, producing distinct flashes of white light and scintillation across the table and facets. The stone is transparent, with a light blue color intensity that is even across the girdle, and an excellent polish that results in crisp facet junctions and minimal surface distortion. Clarity is graded as very slightly included, evaluated at eye level, which indicates only minor internal characteristics that do not detract from the gem s overall transparency or its ability to reflect and refract light.

For the educated buyer this topaz represents a clear value proposition, combining sound gemological attributes with full disclosure of enhancement and origin. The stone has been irradiated to achieve its sky blue hue, a stable and commonly accepted treatment in the trade when properly disclosed, and the origin of Brazil provides provenance from a region known for high quality topaz occurrences. The very slightly included clarity, excellent polish, and well executed mixed brilliant cut together mean this gem will perform strongly in both mounted jewelry and within a curated collection, offering measurable face up presence and reliable brilliance. The Natural Gemstone Company stands behind the description and disclosure of treatments and origin, and this oval sky blue topaz is recommended for collectors and designers who prioritize documented quality, precise cutting, and enduring optical performance. Care recommendations include avoiding excessive heat and harsh chemicals to preserve color stability and polish.
