1.38 Ct. Topaz from Brazil

This is a transparent 1.38 carat oval sky blue topaz, with exact dimensions 8.14 by 6.11 by 3.78 millimeters, offered by The Natural Gemstone Company. The gem is fashioned in an oval outline with a mixed brilliant cut, which blends a brilliant crown with a step influenced pavilion to maximize scintillation and color return. The clarity grade is very very slightly included, evaluated at eye level, and in practical terms the stone is eye clean, with any inclusions visible only under magnification. Color is described as medium intense sky blue, a pleasing balance between pale and deep tones that exhibits attractive saturation under both natural and artificial lighting. The polish is excellent, delivering crisp facet junctions and a reflective surface that enhances overall brilliance. The piece originates from Brazil, a well known source for quality topaz, and it has received an irradiation enhancement to produce and stabilize the blue hue, a common and accepted treatment in the trade that is disclosed in full.

For custom jewelry design this oval gem is particularly well suited because of its size, shape, and proportions. The length and width make it ideal for use as a dominant center stone in rings, pendants, and statement earrings, while the 3.78 millimeter depth yields a total depth that is approximately 53 percent of the average diameter, a proportion that supports balanced light return and stability in settings. The oval shape lends itself to many creative mounting options, including classic four prong settings that showcase the stone face up, bezel mounts that offer protection for everyday wear, east west orientations for contemporary looks, and halo designs that enhance perceived size and color contrast. The mixed brilliant cut ensures lively sparkle even in modestly sized girdles, and the excellent polish allows precision setting without having to compensate for surface irregularities. These characteristics make the gem an efficient choice for custom work where the designer seeks a combination of visual impact, versatility, and workmanship ease.

From the perspective of an educated buyer, the value proposition of this topaz is grounded in objective gemometrics, stable enhancement disclosure, and provenance. The 1.38 carat weight at the stated dimensions is consistent with superior cutting economy, yielding a stone that is large enough to serve as a center gem yet economical compared with larger size brackets. The clarity grade of very very slightly included assures excellent eye cleanliness, which is a critical parameter for pieces intended to read as high quality in finished jewelry. Brazilian origin is notable, because Brazilian topaz deposits have historically produced clean, well colored crystals that respond predictably to standard treatments. Irradiation is a widely accepted and stable enhancement that produces a durable blue color, though like all treatments it should be disclosed to future owners and considered during valuation and insurance. Topaz has a Mohs hardness of 8, offering good scratch resistance for rings and pendants, yet it has perfect cleavage in one direction, so protective settings and care against sharp impacts are recommended.
