2.94 Ct. Topaz from Brazil

One transparent round Swiss blue topaz, 2.94 carat, dimensions 8.09 x 8.11 x 5.98 mm, mixed brilliant cut, clarity grade very very slightly included evaluated at eye level, medium intense color intensity, excellent polish, enhancement irradiation treatment, origin Brazil, offered by The Natural Gemstone Company. The round outline and mixed brilliant pavilion combine to emphasize both scintillation and broad flashes of blue, producing a balanced visual performance at a wearable size. The measured diameter near 8.10 mm places this stone in a versatile category that suits rings, pendants, and earrings, and the 5.98 mm depth supports proportionate light return while retaining a pleasing face up presence. The greenish blue to pure sky blue hue typical of Swiss blue topaz is evident, with saturation that reads as medium intense across photographic and direct viewing conditions. The excellent polish enhances facet crispness and edge sharpness, contributing to overall brightness and surface reflectivity.

From a gemological perspective, the clarity description very very slightly included evaluated at eye level indicates that when viewed unaided in normal lighting the stone is essentially eye clean, with only minute inclusions detectable under careful scrutiny. The mixed brilliant anatomy combines a standard brilliant crown with a pavilion that incorporates facets designed to maximize both return and dispersion, offering a lively balance between sparkle and broad color. The medium intense color intensity is well suited to both cold and warm white metal settings, and the stone responds well to directional lighting, producing internal flash and a pleasing window free face up appearance. Given the measured proportions, a four or six prong setting will secure the gem while allowing table exposure for optimal light interaction, while a bezel setting will provide additional protection for high wear pieces without significantly muting color.

The Swiss blue color in this specimen is produced through irradiation enhancement, a widely accepted and stable treatment for topaz that produces vibrant blue tones from originally colorless or pale material. Following irradiation, routine annealing steps may be applied, and these treatments are industry standard for the Swiss blue variety. Irradiated topaz of this type is considered stable under normal wear conditions, however prolonged exposure to high heat may alter color or clarity, and household chemicals can affect mounting integrity. Professional cleaning recommendations include gentle warm soapy water and a soft brush, avoiding steam and ultrasonic cleaners if the setting contains fillings or delicate prongs. For jewelers fabricating settings, note the exact dimensions 8.09 x 8.11 x 5.98 mm for bezel inner measurements and prong placement, and the carat weight 2.94 provides a reference for overall mass when calculating metal weight and shank proportion.

Beyond physical and gemological attributes, Swiss blue topaz has a long association in various metaphysical traditions with qualities related to calm communication, mental clarity, and measured expression. This variety of topaz is commonly associated with the throat chakra, and is believed by many to support clear articulation, thoughtful speech, and focused listening. Practitioners who work with crystal energy often use Swiss blue topaz to encourage emotional balance, to soothe anxious tendencies, and to enhance concentration during study or creative work. The stone is also regarded as a stabilizer for daytime energy, providing a gentle uplift without overstimulation, and it is frequently combined with complementary stones such as amethyst for heightened intuition, or with moonstone for emotional harmony. These metaphysical associations are cultural and experiential in nature, and are presented as commonly reported qualities rather than scientific claims.
