1.10 Ct. Greenish Blue Paraiba Tourmaline from Brazil

This 1.10 carat cushion shape paraiba tourmaline from Brazil presents an immediately arresting face up presence, with dimensions of 6.95 by 5.97 by 3.89 mm. Cut as a mixed brilliant, the pavilion combines traditional step facet architecture with a brilliant style crown, producing both scintillation and strong return of the stone core color. The material is transparent, evaluated as very slightly included at eye level, which means inclusions are minor and do not materially interrupt light transmission for typical observer distances. The color reads as greenish blue with a vivid electric neon intensity, characteristic of copper bearing paraiba specimens. Polish quality is excellent, with crisp facet junctions and smooth facet planes that support high contrast and sharp facet reflections. Enhancement is by heat treatment, disclosed and stable, applied to refine the tone and remove any undesirable brownish overtones, and the gem is supplied by The Natural Gemstone Company with origin reported as Brazil.

From a faceting and light performance perspective, the mixed brilliant treatment in a cushion outline has been chosen to optimize two competing attributes of paraiba tourmaline, color saturation and brilliance. The brilliant crown facets scatter white light to create the classic scintillation that human observers equate with lively gemstones, while the more angular pavilion facets act to concentrate and return the vivid body color to the table. The relatively deep girdle and measured pavilion depth in this piece preserve the neon saturation when viewed face up, ensuring the electric greenish blue reads strongly under daylight and artificial illumination. Tourmaline is biaxial and commonly pleochroic, and this specimen exhibits measurable pleochroism that shifts between greener and bluer tones when rotated, adding visual complexity. Optical properties typical of tourmaline, including a refractive index range and a modest birefringence, are leveraged by the cutter to balance dispersion and color. The clarity grade very slightly included at eye level indicates that inclusions are small and well positioned, permitting precision cutting without needing to remove significant weight, thereby retaining a desirable 1.10 carat mass while achieving excellent polish and facet symmetry.

When considering historical and famous gemstones, this paraiba presents qualities that resonate with several celebrated stones, while remaining unique in its own right. The neon intensity and pure vibrancy evoke the public fascination that surrounded the discovery of copper rich paraiba tourmalines in Brazil in the late twentieth century, a discovery that created a new standard for what gem connoisseurs describe as electric color. In terms of impact, the vividness of this piece is more akin to the dramatic presence of the Hope Diamond at a small scale, in that its color commandingly dominates the eye, but the mechanism is different, with copper and manganese trace elements producing neon greenish blue rather than the deep blue of carbon and trace elements in that famous stone. Compared with historic greens such as the Dresden Green, which is prized for its deep natural greenness and rarity, this paraiba offers a more saturated neon expression that is rarer among small to medium sizes, particularly when paired with the excellent polish and careful mixed brilliant cutting seen here. For collectors who value color intensity over sheer size, the stone offers a combination of trade desirable traits, including Brazilian provenance, vivid neon color, transparent body, and a stable heat enhancement disclosed by The Natural Gemstone Company.

For practical use and setting recommendations, the 6.95 by 5.97 by 3.89 mm cushion profile and mixed brilliant faceting adapt well to a variety of ring or pendant designs that emphasize face up color. An open prong setting in a neutral white metal will maximize color contrast and allow light to pass through the pavilion, emphasizing the neon character, while a well designed bezel with thin walls can protect the girdle while maintaining color saturation. Given the very slightly included clarity grade, routine jewelry wear is appropriate with normal care, and the disclosed heat treatment is stable under conventional jewelry conditions. For connoisseurs seeking a specimen that delivers an intense paraiba experience in a wearable 1.10 carat format, this Brazilian cushion paraiba from The Natural Gemstone Company represents a technically sophisticated combination of cutter expertise, natural color chemistry, and collector grade attributes, making it ideal for a bespoke engagement setting or as a specialized collectible that stands apart from standard green and blue gemstones in both visual excitement and rarity.
