2.19 Ct. Swiss Blue Topaz from Brazil

This item is a transparent Swiss blue topaz, weighing 2.19 carats, presented in a round shape. The stone measures 7.85 by 7.89 by 5.19 millimeters, and it has been fashioned with a mixed brilliant cut to balance optical performance and proportion. Clarity is graded as very very slightly included, evaluated at eye level, indicating that the stone appears visually clean to the unaided eye while retaining minor internal characteristics under magnification. Color intensity is assessed as medium, and the facet surfaces display an excellent polish. The color has been developed through irradiation, and the material originates from Brazil. These specifications reflect the gem as supplied by The Natural Gemstone Company, with full disclosure of enhancement and origin.

The Swiss blue hue of this topaz is immediately evident, presenting a cool, clear blue that interacts strongly with ambient light. Medium color intensity provides a notable presence without becoming dark, allowing the stone to maintain transparency and internal sparkle. The mixed brilliant cut produces numerous small facets on the pavilion and crown, which promotes even color distribution and a lively pattern of light return. In practical settings the blue will read consistently from multiple viewing angles, and the color will create a distinct focal point when set against pale or neutral mounting materials. The balance of hue and tone will enable the gemstone to stand out as either a center stone or a prominent accent, while retaining the clarity and sparkle expected from a well cut topaz.

Optical performance in this piece is supported by the combination of clarity, cut, and proportions. The very very slightly included clarity grade, evaluated at eye level, means that inclusions are not significant to visual appearance in typical use, and the excellent polish maximizes light transmission through the facets. The dimensions give an approximate depth percentage of 66 percent when compared to the average diameter, a proportion consistent with mixed cuts that prioritize durability and stable setting behavior while still delivering good brilliance. The mixed brilliant design contributes to controlled scintillation, producing crisp flashes that enhance the perceived vibrancy of the blue without introducing excessive contrast or dark areas. Overall, the result is a gemstone that reads as bright and lively, with internal characteristics that do not detract from its visual appeal.

Practical considerations for design and care reflect the material properties and enhancement history. Irradiated topaz offers stable color under normal wear conditions, however prolonged exposure to elevated temperatures such as those encountered during jewelry repair, or exposure to aggressive chemicals, can alter tone and saturation, and should be avoided. Recommended mounting styles to showcase the color include open backed settings and prong designs that permit maximum light entry, and white metals will maintain the cool tonal character while yellow metals can provide a warm contrast for a different visual effect. This Swiss blue topaz, with its specified weight, dimensions, cut, clarity, polish, enhancement disclosure, and Brazilian origin, is supplied with documentation and honest description from The Natural Gemstone Company, allowing designers and craftsmen to make informed decisions about placement and care.
