0.88 Ct. Green (Lime Green) Peridot from China

Imagine a mineral grain that began its journey more than twenty million years ago, deep within the upper mantle, where intense heat and pressure forged olivine crystals in a slowly evolving tectonic environment. Over geologic time, mantle-derived magmas rose through the lithosphere, carrying pockets of peridot bearing peridotite and basaltic xenoliths toward the surface. During a violent volcanic ascent, a fragment of this primitive mantle material was entrained in a basalt flow and deposited within a cooling lava tube. As the host rock cooled, the iron rich olivine rearranged at the atomic scale, producing a gem quality peridot whose lime green color was set by precisely balanced iron and magnesium content. Subsequent weathering and minor metamorphic events polished the raw crystal faces, but the gem retained the internal growth structure that tells the story of formation deep below the crust. The specimen you see is a natural, unenhanced peridot from China, and its clarity and color are direct records of those ancient geologic processes, preserved intact until it was carefully recovered and cut for jewelry use.

From a gemological standpoint this peridot offers excellent attributes for the discriminating buyer, it weighs 0.88 carat and measures 6.05 x 6.01 x 3.80 mm, a size that balances presence and wearability, and it has been fashioned into a round shape with a mixed brilliant cut to optimize face up color and light return. The mixed brilliant design combines a standard crown and brilliant facets with a pavilion structure tailored to peridot optics, yielding lively scintillation while maintaining strong color saturation. The clarity is graded slightly included when evaluated at eye level, and these inclusions are characteristic of natural olivine, often consisting of minute mineral inclusions or planar growth features that do not compromise the structural integrity or polish. The polish is excellent, which enhances surface luster and contributes to optical performance. Chemically peridot is a magnesium iron silicate with a refractive index commonly in the range of approximately 1.65 to 1.69 and a specific gravity near 3.34, properties that give it a bright, lively appearance and a distinct gem feel compared with other green gems. The color intensity is medium, presenting a fresh lime green that reads clearly without appearing weak or overly dark, and importantly this stone has received no enhancement, so its color and clarity are entirely natural.

For an educated buyer the value profile of this peridot lies in the combination of natural origin, gemological transparency, and cutting quality, The Natural Gemstone Company presents this stone with full disclosure, and the absence of treatments enhances its market desirability and long term value. Natural peridot of good color and transparency is relatively uncommon compared with many other gemstones, and pieces under one carat that show clean face up appearance and excellent polish can command premium interest for use in bespoke rings, earrings, or as a complementary center stone in modern minimalist designs. The 6.05 by 6.01 millimeter round offers a classic silhouette suitable for secure bezel or four prong settings that will protect the girdle and show the stone to best effect. Slight inclusions observed at eye level are acceptable within the standard grading framework and often affirm natural provenance when viewed alongside established optical properties. We recommend routine care that avoids sudden thermal shock and harsh chemical exposure, and we suggest periodic professional cleaning to maintain brilliance. The Natural Gemstone Company stands behind the geological origin and the gemological description of this peridot, and we provide documentation of weight, dimensions, cut, clarity assessment, color intensity, polish grade, enhancement status, and country of origin to support confident acquisition decisions.
