Description

This exceptional natural cuprian Paraiba-type tourmaline weighs 6.55 carats and is cut in an elegant pear shape, measuring 13.08 × 10.21 × 7.63 mm. The gemstone displays a vivid greenish-blue hue with strong neon saturation, characteristic of copper-bearing Paraiba-type tourmalines and highly prized in the international gemstone market.

Faceted to enhance brilliance and color dispersion, the stone shows lively internal light return with visible natural inclusions typical for this gemstone variety and size. These inclusions confirm its natural formation and do not detract from its striking visual presence.

Gemological testing by GRS GemResearch Swisslab confirms the stone as a natural tourmaline of cuprian composition (Liddicoatite–Elbaite), originating from Mozambique. The presence of copper and trace elements corresponding to classic Brazilian Paraiba tourmalines is explicitly documented in the report.

Due to its impressive size, certified copper-bearing composition, and vibrant Paraiba-type color, this gemstone represents a rare opportunity for collectors, investors, and high-end custom jewelry creation.

Gemological overview

Technical and gemological information about this gemstone variety.

Gemological profile

Tourmaline refers to a complex group of boron silicate minerals known for their exceptional color diversity, ranging from colorless and black to vivid pinks, greens, blues, and multicolored combinations. Rather than a single gemstone type, tourmaline encompasses multiple species and varieties, each with its own chemical composition and visual character.
Chemically, tourmalines share a complex crystal structure with varying compositions involving elements such as aluminum, iron, magnesium, lithium, and sodium. All tourmalines crystallize in the trigonal crystal system and belong to the silicate mineral group. In gem-quality material, tourmaline typically displays a vitreous luster with transparent to slightly translucent clarity.
Refractive index values in tourmaline generally range from approximately 1.62 to 1.65, contributing to good brilliance and strong color saturation. Tourmaline is found in many regions worldwide, with notable sources including Brazil, Afghanistan, Pakistan, Madagascar, Mozambique, and parts of Africa, depending on the specific variety.

Durability & suitability

With hardness values typically ranging from 7 to 7.5 on the Mohs scale, tourmaline offers good durability suitable for a wide range of jewelry applications when properly set and worn with standard care. Its lack of cleavage contributes to reliable resistance against everyday wear.
Most tourmaline varieties perform well in rings, pendants, earrings, and bracelets, particularly when set in designs that provide reasonable protection. While durability can vary slightly between individual tourmaline species, the group as a whole is well suited for both everyday jewelry and expressive, statement-oriented designs.

Treatments & authenticity

Tourmaline is commonly found in nature without the need for enhancement. In some cases, heat treatment or irradiation may be applied to improve color or clarity in certain varieties, practices that are accepted within the gem trade when properly disclosed.
Any treatments or enhancements, if present, are always clearly stated for each individual gemstone. Every stone is professionally examined, and transparent disclosure is regarded as a fundamental part of responsible gemological practice, allowing clients to make informed and confident decisions.
