23.43 Ct. Swiss Blue Topaz from Brazil

This listing presents a transparent 23.43 carat pear shape Swiss blue topaz, dimensions twenty point four one by fifteen point three one by nine point six two millimeters, faceted with a mixed brilliant cutting scheme, clarity graded as very slightly included at eye level, vivid color intensity, and an excellent polish. The pear proportions yield a length to width ratio of approximately one point three three, and the depth equates to roughly fifty four percent of the average diameter, a profile optimized to balance face up spread and pavilion light return. The mixed brilliant design employs a brilliant crown to enhance scintillation and a modified pavilion geometry to preserve color saturation, producing strong blue flashes and broad white brilliance that animate the stone when viewed in motion. Origin is Brazil, enhancement by irradiation following industry best practices to achieve the Swiss blue tone, and the surface finish demonstrates crisp facet junctions and mirror polish, attributes that reduce light leakage and maximize apparent transparency.

From a gemological and crafting perspective the cutting emphasizes optical performance rather than mere weight retention. The mixed brilliant layout concentrates smaller star and kite facets on the crown to break large white flashes into lively scintillation, while the pavilion facet angles are calibrated to return light through the crown without washing the hue, an important consideration for vivid blue topaz. The clarity described as very slightly included at eye level indicates only minor pinpoint or needle inclusions that do not materially affect the gem’s transparency or structural integrity, and the excellent polish preserves facet crispness for maximum reflected brilliance. With a hardness near eight on the Mohs scale and stable color from controlled irradiation under standard conditions, this gem is suitable for ring focal points and pendants that require both durability and striking visual presence.

When compared to famous historical blues, this Swiss blue topaz offers a different but complementary appeal. It does not share the high dispersion of a diamond such as the Hope Diamond, yet it rivals famous blue stones in sheer presence and wearable scale, recalling the commanding hue of renowned sapphires while remaining lighter in tone and more lively in brilliance. The twenty three point four three carat weight places it among the larger fine Swiss blue topaz examples available, offering collectors and jewelers an opportunity to secure a statement gem that combines classical pear elegance, precision cutting, and eye level clarity.
