2.19 Ct. Green (Lime Green) Peridot from Tanzania

This 2.19 carat emerald cut peridot from Tanzania exemplifies how crystal structure and expert cutting combine to produce a brightness and presence that educated buyers will readily appreciate, The Natural Gemstone Company is pleased to present this transparent lime green peridot, with exact dimensions of 8.69 by 6.09 by 4.95 millimeters, an emerald cut, and a clarity grade of very slightly included evaluated at eye level. Peridot is an olivine group mineral with a gem formula dominated by magnesium and iron, and that orthorhombic crystal structure produces a distinct optical behavior. The refractive index range typical for peridot concentrates light within the stone, while measurable birefringence produces subtle directional brightness when the gem is viewed from different angles. In this particular gem the intense color intensity works in concert with the cutting lines, the excellent polish, and the natural optical properties of peridot to deliver broad, luminous flashes of lime green rather than a scatter of spectral fire. An emerald cut emphasizes color and clarity, creating a hall of mirrors effect that shows off internal planes and clean facets, and for a high quality peridot like this one the result is a sophisticated and luminous appearance that remains restrained and elegant.

For buyers trained in grading and gemology the clarity and treatment history are crucial components of value, and this peridot is notable because it is unenhanced, with no heat or chemical treatments applied. The clarity description of very slightly included evaluated at eye level means that inclusions are minimal, do not materially interrupt the stone's transparency, and rarely distract the eye when set, which is a desirable attribute for a step cut that places emphasis on internal features. The emerald cut requires a stable and well distributed color to avoid dark corners and to maximize the apparent size through table and step facets, and this specimen achieves that balance with its intense, evenly distributed lime green. The excellent polish contributes to the stone retaining crisp facet junctions and smooth facet planes, which increases effective light return in a step cut and enhances the apparent saturation and depth of the peridot. For a discerning purchaser assessing per carat value, provenance plays a role, and Tanzanian peridot is recognized in the trade for consistent color saturation and gem quality specimens originating in volcanic and mantle related contexts.

The way this peridot sparkles is an interplay of intrinsic optical constants and the cutter's decisions, and explaining that interaction clarifies why this gem is more valuable than similar sized but poorly cut stones. Peridot has a relatively high refractive index for a green gem, which increases brilliance when facets are aligned to the optical axes, and its birefringence, while modest, can add a lively two dimensionality to facets that are oriented across different crystallographic directions. The emerald cut used here favors broad, reflective planes that create dramatic, parallel flashes of light as the gem is moved, a type of brilliance that appeals to collectors who appreciate controlled light dynamics rather than random scintillation. Because the gem is not treated, the intense lime green color is natural and stable, derived from iron substituting in the crystal lattice, and this makes the color both diagnostic and desirable. Additional factors such as specific gravity and the absence of internal stress or fractures influence how light is transmitted and reflected, and this peridot exhibits the optical clarity and structural soundness that preserve brilliance over time when the gem is properly set and cared for.

For purchasers considering this peridot for investment, bespoke jewelry, or as part of a comparative collection, practical information about use and complementary pieces is important. The emerald cut peridot is ideally suited to settings that protect the girdle and corners, while allowing the table to face up and reveal the gem clarity and color, and prong settings with a low profile or a bezel with precise edge work are recommended to minimize exposure to knocks. Cleaning with warm soapy water and a soft brush is preferred, avoiding steam and aggressive ultrasonic cleaners when inclusions are present, and routine inspections of the setting will maintain the gem s visual performance. As a point of contrast and for collectors who enjoy pairing complementary gems, The Natural Gemstone Company also offers fine examples of Semi-Black Opal, a type of opal characterized by a darker body tone that provides dramatic play of color and strong contrast against lighter green stones such as this peridot. A Semi-Black Opal paired with this Tanzanian peridot creates an appealing dialogue between vivid lime green and multicolored opal fire, and because both gems can be sourced and described with precise grading parameters a knowledgeable buyer can curate a set that balances color theory, optical effects, and long term collectability.
