1.38 Ct. Greenish Blue Paraiba Tourmaline from Mozambique

This 1.38 carat oval greenish blue Paraiba tourmaline from Mozambique is presented with precise gemological parameters that will appeal to technically minded buyers. The stone measures 8.09 by 6.29 by 3.82 millimeters, yielding a depth percentage of approximately 53.1 percent when using the average diameter, a proportion that sits well within the range preferred for a mixed brilliant oval to balance light return and spread. The cutter employed a mixed brilliant faceting scheme, combining a faceted crown with a brilliant-style pavilion to maximize scintillation while preserving color. Clarity is graded as included at eye level, which denotes visible internal features when examined unaided but without severe impact on overall transparency. Color intensity is described as faint greenish blue, a subtle tone that exhibits Paraiba’s characteristic copper-influenced hue without the saturation seen in top-tier specimens. The gem is untreated, confirmed as no enhancement, and shows excellent polish across all facet junctions and the girdle, indicating careful lapidary work consistent with professional standards at The Natural Gemstone Company.

The mixed brilliant design used on this oval offers a technical compromise between color saturation and brilliance. The brilliant-style pavilion facets are oriented to return light through the crown while the step-influenced crown facets create broader flashes that help reveal the stone’s greenish blue nuance. Given the faint intensity, the cutting emphasis is on even facet alignment and a moderate pavilion depth to avoid color leakage that could make the stone appear washed out in daylight. The measured dimensions paired with the 1.38 carat weight indicate a slightly shallower pavilion than deep-cut tourmalines, which enhances perceived spread on the finger or in a pendant. The excellent polish contributes to strong facet reflection and crisp windowing control, so despite the included clarity grade, the stone delivers clear optical performance under both diffused interior lighting and brighter outdoor conditions. Mozambique as the origin is significant for copper-bearing tourmalines; in this piece the copper content manifests as a cooler, green-leaning blue rather than the intense neon blue of some Brazilian Paraiba examples, creating a distinctive and collectible color profile.

Inclusions are a defining aspect of this gem, and their presence should be interpreted technically rather than negatively. The included grade indicates internal crystals, narrow feathering, or healed fractures that are visible at normal viewing distance. These internal features are typical for Paraiba material and in many cases contribute to the stone’s identity and stability. Because the polish is excellent and facet junctions are well executed, the inclusions are often visually integrated into the overall appearance rather than creating disruptive light leakage. From a durability standpoint, tourmaline has a Mohs hardness of approximately 7 to 7.5 and lacks true cleavage, but it does exhibit striations and can be susceptible to impact along prismatic directions. The current stone’s proportions and consistent girdle thickness suggest secure setting possibilities without undue risk of chipping if mounted properly. Importantly for collectors, the piece is natural and unenhanced, which preserves both market value and the authentic material properties associated with Mozambique-sourced Paraiba tourmalines.

Versatility is a strong selling point for this 8.09 by 6.29 millimeter oval. The measured spread and mixed brilliant faceting make it equally appropriate for a refined everyday ring and a formal evening pendant. For daily-wear ring settings, a low-profile bezel or a protective halo with close-set micro-prongs will shield the girdle and pavilion while allowing the mixed brilliant facets to perform. For maximum light return in dress contexts, a four-prong solitaire that elevates the crown will enhance scintillation and let the greenish blue tone interact dynamically with ambient lighting. The size is equally suitable for bespoke cufflinks or as the focal point in a bespoke three-stone design paired with neutral side stones that accentuate the copper-derived hue. Recommended care includes avoiding thermal shock and harsh chemical exposure, and cleaning should be limited to mild detergent with a soft brush rather than steam or ultrasonic cleaning when inclusions are prominent. As with all specialty material from The Natural Gemstone Company, this Paraiba tourmaline is accompanied by provenance and treatment disclosure; our lapidary and sales teams can provide further measurements, high-resolution facet maps, and custom mounting options to ensure the gem’s technical attributes are optimized for your intended use.
