4.51 Ct. Cabochon Tourmaline from Mozambique

This listing from The Natural Gemstone Company describes a translucent green tourmaline weighing 4.51 carat, presented in an oval shape with dimensions of 11.03 x 9.00 x 5.14 mm. The gem is fashioned as a cabochon, a cut that emphasizes color saturation and internal luster rather than faceted brilliance, and it displays an excellent polish that enhances surface smoothness and light diffusion. Clarity is graded as very slightly included, evaluated at eye level, which indicates minor internal features that are visible under close inspection but do not detract from overall visual appeal. These inclusions are typical for natural tourmaline and can serve as fingerprint like indicators of natural origin, often desirable to collectors who prioritize untreated material. Color intensity is described as light, offering a soft green tone that reads elegant and versatile in many jewelry designs. Importantly, this stone has no enhancement, preserving its natural state and making it attractive to buyers who value untreated provenance. The reported origin is Mozambique, a well known source for high quality tourmalines, lending additional provenance value and helping establish market comparability for grading and pricing.

For the educated buyer, this specimen presents several points of value and practical considerations. The 4.51 carat weight combined with a cabochon oval measuring just over 11 by 9 mm makes this a substantial and wearable stone for rings, pendants, or bespoke pieces where a smooth domed surface is preferred. Tourmaline ranks around seven to seven and a half on the Mohs hardness scale, offering good everyday durability when set with basic protective measures, and the cabochon form reduces vulnerability to chips compared with sharp faceting. The very slightly included clarity grade indicates internal features that generally do not affect structural stability, while the lack of enhancement maintains market desirability and simplifies future resale or certification. Origin from Mozambique is a recognized provenance that supports consistent market expectations for color and inclusion pattern, and our documentation and imaging at The Natural Gemstone Company aim to provide transparent information for appraisal and insurance. For collectors and designers seeking a naturally formed, well polished, untreated green tourmaline with clear provenance and pleasing size, this gem represents a balanced combination of aesthetic appeal and gemological integrity.
