42.01 Ct. Cabochon Tourmaline from Madagascar

This pear shape bluish green tourmaline weighs 42.01 carats, a substantial and noteworthy size for this species, and is presented by The Natural Gemstone Company as a premium example of color and form. The gem measures 52.10 x 13.10 x 6.70 mm, and its elongated cabochon cut emphasizes depth of tone and a satiny, luminous surface, with an excellent polish that produces clean reflected highlights. The translucent body combined with intense color intensity creates a strong visual presence, and the smooth pear silhouette suits single stone pendants and bespoke high end jewelry where scale and density of color are key design elements. At 42.01 carats the weight itself is a primary value driver for an educated buyer, because larger tourmalines with uniform, saturated color and superior finishing are relatively uncommon on the market, and sizable pieces command premium consideration from collectors and designers who prioritize both statement aesthetics and gemological quality.

From a gemological perspective this specimen is graded clarity included, evaluated at eye level, which is typical for natural tourmalines and often reflects characteristic fluid inclusions and growth features that attest to natural origin. These internal characteristics should be considered part of the gem provenance rather than defects, especially in a cabochon where inclusions can contribute to depth and character without disrupting the surface brilliance. The stone has been enhancement heat treated, a standard and stable practice used to optimize hue and reduce unwanted brownish overtones, and this treatment is disclosed and consistent with trade norms. Origin Madagascar is an important descriptor, because Madagascan tourmalines are recognized for their vibrant and diverse color range, geological sources that produce well crystallized material, and an established supply history that collectors respect. When assessing market value, an educated buyer should weigh carat weight, color saturation, polish quality, clarity at eye level, treatment disclosure, and documented origin together, and this example scores highly across those criteria.
