37.15 Ct. Topaz from Brazil

This Swiss blue topaz is a transparent, oval shape gemstone weighing 37.15 carats, measuring 22.50 x 18.60 x 12.40 mm, with a mixed brilliant cut that balances faceting for face up brilliance and depth, and an eye clean clarity as evaluated at eye level. The stone exhibits a medium intense color intensity, presenting a clear, vivid blue that benefits from excellent polish and precise facet execution. Originating from Brazil, the material has been enhanced by irradiation, a stable and industry accepted treatment for producing the Swiss blue hue, and full disclosure of this enhancement is provided by The Natural Gemstone Company. The combination of size, transparency, and cut allows the gem to display strong light return and scintillation, and the dimensions make it suitable for a bold pendant or a statement ring setting, while the mixed brilliant faceting optimizes visual performance in a variety of mounting styles.

From an investment perspective, this 37.15 carat Swiss blue topaz occupies a distinctive position within the colored gemstone market, large, eye clean specimens in attractive blue tones are less common than smaller commercial material, and size contributes positively to scarcity and secondary market interest. While irradiation is an established enhancement that does not typically compromise stability, transparent disclosure and documented origin increase buyer confidence and support long term value, and The Natural Gemstone Company provides provenance information to assist in market placement. Future appreciation potential depends on quantifiable factors, including continued demand for blue gemstones, supply changes from Brazilian sources, the relative rarity of well cut large topaz that is eye clean, and evolving collector preferences. Historically, topaz trades at lower per carat levels than some other blue gemstones, however exceptional examples that combine notable carat weight, attractive color, and superior cutting can achieve outsized premiums during periods of increased collector focus. For investment minded clients, obtaining independent certification, maintaining careful custody, and considering conservative valuation and insurance are recommended steps to preserve liquidity and value. This natural Swiss blue topaz, offered with clear disclosure by The Natural Gemstone Company, represents a tangible, wearable asset with both aesthetic appeal and documented characteristics that support its consideration for inclusion in a diversified gemstone portfolio.
