0.80 Ct. Yellowish Green Peridot from Tanzania

This listing from The Natural Gemstone Company presents a single transparent peridot, cut in an elegant emerald shape, weighing 0.80 carat, with finished dimensions of 6.43 by 4.88 by 3.09 millimeters. The cutting style is faceted, executed to present clean lines and step facets that emphasize the stone geometry and promote controlled light return. The gem displays a yellowish green hue, evaluated at medium color intensity, and it has received an excellent polish that produces crisp facet junctions and a smooth table surface. Clarity is graded as slightly included when observed at eye level, noting small natural inclusions that are typical for peridot and that do not materially detract from overall transparency. The piece is natural and untreated, with no enhancement, and is documented as originating from Tanzania, a source known for producing lively and well colored peridot material. This description is provided to assist buyers who expect clear, transparent disclosure and accurate gemological information from The Natural Gemstone Company.

From a gemological perspective this peridot exhibits the classic optical properties of the olivine group, with a refractive index range that places it between common gem species and offers a pleasing balance of brilliance and stability. Peridot typically has a refractive index approximately in the range of 1.654 to 1.685 and a birefringence that can be noticeable as a subtle doubling of facet edges in certain orientations, characteristics that contribute to its distinctive internal light behavior. Luster is vitreous and the medium color intensity of this stone allows good light transmission through the table and crown, producing clean face up color without appearing overly dark or washed out. The emerald cut accentuates the stone color and clarity, because step cutting prioritizes color saturation and windowing over extreme scintillation, making it ideal for peridot where pure, clean green tones are prized. The excellent polish enhances surface reflectivity, while the absence of treatments means that the optical character you see under natural light is the original expression of the material from the Tanzanian mine.

When comparing reflective qualities with other gemstones in the green category it helps to consider both refractive index and dispersion, as well as typical clarity. Compared to emerald, which usually has a lower refractive index and a high incidence of fissures and inclusions, this peridot will tend to present a brighter, more uniformly transparent face up appearance because peridot often has fewer large surface reaching fractures and because the emerald cut here reveals clarity more directly. Against green tourmaline, which can show pleochroism and deeper color saturation, this peridot offers a lighter, more yellowish green that catches and returns light with a more consistent hue across table and pavilion, and tourmaline tends to exhibit stronger color zoning and different light dynamics. Compared to tsavorite garnet, which has a higher refractive index and noticeably stronger brilliance and fire, this peridot is more modest in dispersion but compensates with a fresh, lively green that reads well in both daytime and artificial lighting. Versus demantoid garnet, noted for exceptional dispersion and fire, peridot does not aim to match that spectral flash, rather it delivers a more restrained, glassy brilliance and a clean, natural green that feels organic and wearable daily. The emerald cut further moderates sparkle in favor of color presentation, which is appropriate for buyers who prioritize hue purity and clarity.

Clarity and inclusion patterns in peridot are important considerations for valuation and setting recommendations. This stone is graded slightly included at eye level, indicating small internal features visible to a careful observer but not large enough to compromise durability or overall appeal. Typical peridot inclusions can include fine needles and occasional darker mineral crystals, often chromite, which are part of the gem story and can help confirm natural origin. Because the gem is untreated, those inclusions are left in their natural state and contribute to gemological authenticity. For everyday wear, peridot has a hardness in the range of 6.5 to 7 on the Mohs scale, so settings that offer some protection such as bezels or partial bezels are often recommended, or protective prong settings that keep the girdle and corners secure. The emerald cut profile and stable pavilion depth of 3.09 millimeters in this example create a low to moderate crown height and a pleasing table area that makes the most of the stone color while maintaining a profile that sits well in rings and pendants. Cleaning with warm water, mild soap, and a soft brush is advised, and ultrasonic cleaning should be avoided unless a professional has confirmed there are no stress related inclusions.

For the educated buyer, the value proposition of this Tanzanian peridot lies in its combination of weight, cut quality, natural origin, and lack of enhancement. At 0.80 carat, the gem sits in a size range that offers practical wearability without the premium step up in price associated with larger parcels, and the emerald cut amplifies perceived clarity and color uniformity. The medium intensity yellowish green is a color many collectors and designers seek because it photographs well and adapts to both warm and cool metal settings. The fact that the stone is natural and untreated from Tanzania is a key point for buyers who prioritize provenance and minimal intervention, and The Natural Gemstone Company presents this information transparently to support informed purchasing decisions. When assessing reflective performance compared to other green gems, consider that this peridot favors a clean, glassy luster and steady face up color rather than extreme dispersion or scintillation, which makes it particularly suitable for elegant, classic jewelry designs where color and clarity are the central attributes.
