This transparent 2.66 carat asscher octagon white topaz presents a precise and elegant geometry, measuring 7.81 x 7.13 x 5.20 mm, with an Asscher cut that emphasizes step faceting and internal brightness. The gem is graded as very slightly included, evaluated at eye level, and displays a near colorless intensity with an excellent polish that enhances brilliance and scintillation. Enhancement by irradiation is declared, a common and stable treatment for white topaz that produces consistent color without compromising structural integrity when properly disclosed. The material is sourced from Ceylon Sri Lanka, a region with a respected history for producing clean and well formed topaz crystals. Opal type White Opal is noted as a complementary offering within our assortment, suitable for coordinated designs or for collectors who seek visual contrast between a colorless faceted stone and a soft play of color in an opal.
From an investment perspective this white topaz occupies a measured position within the broader gemstone market, combining accessible acquisition cost with attributes that support collector interest. The Asscher cut at this carat weight is less common for topaz than round or oval cuts, which can increase desirability for designers and collectors seeking distinctive faceting. Provenance from Ceylon Sri Lanka, together with transparent documentation of the irradiation enhancement and the clarity and polish grades, contributes positively to market confidence and resale transparency. While topaz historically appreciates more modestly than rarer gemstones such as sapphire or emerald, well documented examples that present superior cut, eye clean clarity, and unique proportions have shown steady demand in specialized channels, particularly when offered by reputable houses.
Long term appreciation will depend on supply dynamics, consumer preferences, and the retention of provenance and documentation, factors that tend to favor stones sold with clear disclosure and trusted origin. Strategic pairing with a White Opal can provide aesthetic and portfolio diversification, appealing to collectors who value complementary combinations. The Natural Gemstone Company maintains thorough records for each gemstone, and we recommend formal appraisal and secure storage to support future liquidity. This white topaz is well suited for elegant bespoke settings, and for collectors seeking a distinctive, documented stone with considered investment potential.
