1.18 Ct. Green (Lime Green) Peridot from Tanzania

This transparent 1.18 carat pear shape peridot, with dimensions 8.03 by 5.99 by 4.06 mm, exemplifies how mineral structure and thoughtful cutting combine to produce exceptional brilliance. Peridot is the gem quality form of the silicate mineral olivine, and its orthorhombic crystal lattice gives it distinct optical behavior, including a refractive index around 1.65 to 1.69 and measurable birefringence near 0.036 to 0.039. Those optical properties allow well placed facets to split and refract light into intense internal reflections, and the mixed brilliant cut on this specimen enhances both scintillation and overall light return by combining the crisp flash of brilliant facets with the depth and contrast of step facets. The medium lime green color is pure and lively, the clarity is assessed as very very slightly included evaluated at eye level, and the excellent polish maximizes surface reflection and precise facet junctions, producing a sparkle that reads as lively and lively across the table and pavilion faces.

From a grading and provenance perspective, this peridot offers attributes that matter to an educated buyer, collectors and gemologists alike. The lack of any enhancement is significant, as natural, unenhanced peridot retains its value and predictability in stability and wear. Origin from Tanzania places this stone within a recognized and responsibly sourced supply region, and the combination of transparency, medium color intensity, and VVS level clarity makes it suitable for fine jewelry settings where both durability and optical performance are required. For buyers interested in matching or pairing with other gem types, we note that the opal type we reference in our complementary collections is Semi-Black Opal, a variety valued for its darker body tone and pronounced play of color, which can create striking contrast with lime green peridot. At The Natural Gemstone Company we document cut, measurements, clarity observations and enhancement status to support provenance and valuation, and this peridot represents a well documented, attractively cut example of its species, delivering optical performance and rarity parameters that informed buyers use to assess long term desirability.
