2.18 Ct. Green (Lime Green) Peridot from Tanzania

This description presents a single, transparent, 2.18 carat emerald cut peridot from Tanzania, a notable specimen that combines substantial weight with exceptional cut quality. At 2.18 carats this peridot sits above the median commercial size for gem quality peridot, a factor that materially affects its rarity and market value. Weight is a primary determinant of peridot valuation because larger clean crystals capable of yielding well proportioned cuts are uncommon, and the incremental price per carat increases as size rises while maintaining high color saturation and transparency. The stone measures 7.77 by 6.85 by 5.10 millimeters, dimensions that translate into a visually commanding face up area while preserving an ideal balance between table size and depth for the emerald cut shape. The lime green hue is recorded as intense in color intensity, a saturation grade that enhances optical presence and therefore supports a higher per carat price bracket when combined with the clean, transparent body seen in this example.

The faceting regimen is an emerald cut executed with precise step cut faceting and crisp facet junctions, a stylistic choice that emphasizes color and clarity over scintillation. The large step facets on the crown and pavilion create a series of broad reflective planes that produce a hall of mirrors effect, which in turn allows the intense lime green hue to read with evenness across the table and along the crown facets. With the reported dimensions the depth is approximately 69.8 percent of the average diameter, a depth ratio that is within the expected range for a well proportioned emerald cut peridot and which contributes to controlled light return and even color distribution. The table is proportioned to present the color boldly without sacrificing pavilion volume, and the girdle is handled to provide secure mounting options while avoiding excessive thickness that would add unnecessary weight without contributing to optical performance. The polish is graded excellent, indicating meticulous lapidary finishing that yields smooth facet planes and sharp facet junctions, a technical detail that maximizes brilliance and minimizes light leakage.

The clarity grade is slightly included as evaluated at eye level, a classification that indicates the presence of minor internal features visible to an analyst without magnification, but which do not materially interrupt the gem translucent to transparent character or the overall appeal of the stone. In peridot, typical internal characteristics can include small crystals or growth related features, and in many cases these inclusions serve as identifiers of natural origin rather than detractors of beauty. Because this material is unenhanced, with no heat or clarity treatments reported, the inclusions are consistent with natural formation and the transparency remains high, allowing the intense lime green to register vividly. The absence of enhancement is technically significant, as untreated peridot retains its natural lattice chemistry and color centers, and untreated larger stones are proportionally rarer. Origin from Tanzania further informs both geological character and market positioning, as Tanzanian peridot is known among connoisseurs for lively green hues with a slight yellowish bias toward lime green, and it is often sought after for secure supply provenance.

From a rarity and jewelry design perspective, the 2.18 carat weight is a decisive factor. Peridot larger than two carats with intense color and clean appearance commands a premium because cutters must select rough of sufficient size and low fracturing to produce a single, high quality gem. The emerald cut here is a deliberate cutter choice that preserves weight while optimizing color saturation and clarity display, and the excellent polish reflects skilled finishing that is required to produce symmetrical step facets and crisp pavilion angles. For designers and collectors, this stone is suitable as a dominant center stone in a ring, a substantial pendant focal point, or a museum quality pairing in a matched study. When pricing and provenance are considered, the combination of weight, intense hue, transparency, no enhancement, and Tanzanian origin position this peridot in an upper tier of market desirability. For clients exploring complementary pieces or paired sets, our offerings also include semi precious opal material, specifically Semi Black Opal examples that can be selected to contrast and highlight the lime green peridot tone in bespoke designs.

The Natural Gemstone Company stands behind the technical specification and provenance of this 2.18 carat emerald cut peridot, and we supply detailed measurements and grading parameters to assist in technical appraisal and setting design. For advanced buyers who prioritize lapidary technique, the information on depth ratio, facet architecture, clarity at eye level, and polish grade provides an objective basis for valuation and comparison. For those commissioning custom work, the stone mounts well in precision settings that respect the girdle profile and that leverage the emerald cut facade to emphasize linear geometry and color field. Because the piece is supplied without enhancement, it is an excellent candidate for collectors and designers who demand natural material that will not alter with routine exposure to light or heat. For additional consultation on matching stones, alternate cuts, or complementary gems including Semi Black Opal, our gem specialists at The Natural Gemstone Company are available to provide technical comparisons and recommendations based on optical performance, durability, and design intent.
