1.12 Ct. Tourmaline from Tanzania

This offering from The Natural Gemstone Company is a beautiful transparent green tourmaline weighing 1.12 carat, presented in an elegant oval shape with dimensions 7.64 by 5.05 by 3.87 mm, and finished with a mixed brilliant cut. The mixed brilliant cut combines a faceted crown designed to maximize scintillation with a pavilion that supports depth of color, resulting in a gem that strikes a balance between lively sparkle and consistent color saturation. This stone carries an intense color intensity, a clarity grade described as very slightly included when evaluated at eye level, and an excellent polish that enhances surface brightness and edge definition. Enhancement status is none, which means the stone shows its natural color and clarity characteristics without treatment, and the origin is Tanzania, a source known for producing tourmalines with pleasing tones and reliably good transparency. For the educated buyer who values both gemological integrity and visual performance, these specific details matter, because they define how the gem will behave in a finished setting, how it will interact with light, and how it will hold its value over time.

Optical behavior of this green tourmaline is noteworthy, because tourmaline is a pleochroic mineral, and this particular gem displays distinct color zoning and directional color shifts under changing light angles, a trait that can be used creatively by cutters and designers to emphasize either a yellowish green or a deeper forest green hue depending on orientation. Reflective qualities in tourmaline arise from a refractive index range that is moderate compared with other gem species, and from the gem being singly or weakly birefringent, which in practical terms translates to a lively but not overpowering brilliance. Compared with higher refractive index stones such as sapphire or diamond, this tourmaline will show less mirror like reflection and less dispersion, however it compensates with a combination of vivid color saturation and lively facet contrast when well cut. The mixed brilliant style increases flash and scintillation, while the excellent polish ensures that light is reflected cleanly from facet to facet, giving the gem a crisp and lively appearance in hand or under jewelry lighting.

When contrasting this Tanzanian green tourmaline to other green gemstones in its category, several points of comparison should be considered, including brilliance, color saturation, pleochroism, hardness, and rarity. Compared with emerald, tourmaline is typically less included at face up inspection in fine pieces, and it will exhibit higher transparency in many examples, while emeralds often command value for their classic pure green tones and historical prestige despite their common clarity issues and frequent treatment. Against tsavorite garnet, tourmaline offers a wider palette of green hues and stronger pleochroism, while tsavorite typically displays very lively brilliance due to a higher refractive index and strong dispersion, which makes tsavorite appear more fiery and sparkly under point light. Against green sapphire, tourmaline again shows stronger pleochroic tendencies and a different kind of color depth, while sapphire will typically present higher brilliance and a more mirrorlike reflection due to its higher refractive index. Peridot tends to have a yellowish green tone and higher birefringence, but peridot can show cleavage and sensitivity to wear in different ways. In practical use for jewelry that balances color intensity and day to day wearability, tourmaline sits in a favorable position, offering intense color, good durability for most settings, and a more affordable per carat cost than top emerald or sapphire material in comparable sizes and color grades.

From a connoisseur and investment perspective, the combination of factors present in this piece from The Natural Gemstone Company enhances its appeal. The lack of enhancement signals that the intense green hue is natural, which is a quality attribute for collectors seeking untreated gems. The very slightly included clarity grade suggests that inclusions are minimal at sight, so the gem will present cleanly in most jewelry designs, and the mixed brilliant cut paired with excellent polish means that the cutter prioritized both color retention and optical performance. Origin from Tanzania adds provenance value, because East African localities have become respected sources for tourmaline with attractive tones and consistent clarity. For designers and buyers, this stone will set well in white or yellow metals, and its size and shape are versatile for rings, pendants, or bespoke pieces that require an elegant oval profile. For buyers who compare reflective qualities and overall gem performance, this tourmaline offers an appealing compromise between color vibrancy and lively facet play, making it a smart choice for those who want a gemstone with personality, reliable optical performance, and verified natural origin.
