2.19 Ct. Topaz from Brazil

One beautiful transparent 2.19 carat round Swiss blue topaz is presented with precise proportions and careful finishing, a gem that exemplifies controlled color and refined cutting from The Natural Gemstone Company. The stone measures 7.85 x 7.89 x 5.19 mm, a near perfectly proportioned round that benefits from a mixed brilliant cut. Clarity is assessed as very very slightly included when evaluated at eye level, a grade that indicates exceptional visual purity and minimal impact on light performance. The color registers as medium intense, a balanced and vivid blue that is characteristic of Swiss blue topaz, and the surface shows an excellent polish that enhances both brightness and surface smoothness. This topaz originates from Brazil, and its color has been produced by irradiation, a commonly used and stable enhancement applied to topaz to achieve the characteristic Swiss blue tone.

The medium intense Swiss blue color of this topaz will stand out in virtually any jewelry setting because of its clarity, even saturation, and the way its mixed brilliant cut distributes light. The hue sits in a cool blue range that reads as lively and luminous against reflective metals, creating a focal point that draws the eye. In white metal settings such as platinum or white gold, the blue reads pure and crystalline, with the metal acting as a neutral reflector that emphasizes internal scintillation. In yellow gold, the coolness of the blue creates a pleasing color contrast that makes the stone appear slightly more vivid, a classic combination that balances warmth and clarity. Against rose gold, the blue offers a contemporary contrast that highlights the stone without overwhelming its tone. Because of its excellent polish and transparency, the gem performs well in both open prong settings that maximize light entry, and in partially enclosed settings that emphasize the color while protecting the girdle.

The mixed brilliant cut and the precise dimensions of 7.85 x 7.89 x 5.19 mm produce an optical presentation that is versatile for a range of jewelry types, from a solitaire ring center to a pendant focal point, and paired stud earrings. The cut combines a faceting scheme that promotes strong brilliance from the crown with a pavilion arrangement that returns light effectively through the table. With a weight of 2.19 carats, the stone occupies a visually significant presence on average finger proportions, providing a balance between statement and wearable elegance. The very very slightly included clarity grade indicates that any internal features are small and generally not distracting at typical viewing distances, which preserves both sparkle and aesthetic purity. The excellent polish contributes to crisp facet junctions and high light return, so the stone exhibits lively scintillation in natural and artificial light, enhancing the perception of depth and making the blue color read consistently across viewing angles.

Because this topaz has been enhanced by irradiation to achieve its Swiss blue color, it is important to understand the nature and implications of that treatment and the practical care considerations for long term wear. Irradiation is an industry standard for producing blue topaz hues, and when properly performed it yields stable color under normal wearing conditions. The gem retains topaz mineral durability, with a hardness that makes it suitable for many types of jewelry including rings, pendants, and earrings, though care should be taken to protect it from hard knocks and prolonged exposure to very high temperatures. For routine maintenance, warm soapy water with a soft brush is recommended, and avoidance of harsh chemical cleaners or prolonged exposure to intense heat will preserve the integrity of the treatment. When considering a setting, open prong styles maximize light entry and color saturation, while secure bezel or partial bezel settings increase protection for active wearers.
