1.07 Ct. Yellowish Green Peridot from Tanzania

This transparent 1.07 carat emerald cut peridot measures 7.65 x 4.78 x 3.53 mm, and it presents an intense yellowish green color that is immediately striking to an educated buyer. Faceted into a classic emerald cut, the stone exhibits crisp step facets and an excellent polish that together maximize its color saturation and table brilliance. The clarity is graded slightly included at eye level, which is typical for natural peridot and confirms its authenticity without undermining its visual appeal. No enhancements have been applied, so the color and clarity are wholly natural, and the provenance from Tanzania adds geological interest and market appeal. For those who evaluate gems by scientific criteria, peridot typically shows a refractive index in the range of approximately 1.65 to 1.69, a specific gravity near 3.2 to 3.4, and a hardness around 6.5 to 7 on the Mohs scale, all of which make this gem durable enough for everyday jewelry when set responsibly. The combination of size, intense natural color, transparency, and an excellent cut and polish make this Tanzanian peridot a rare and attractive option for collectors and connoisseurs seeking a premium unenhanced olivine specimen.

The story of how this peridot formed millions of years ago enhances its value to an informed buyer, because it connects beauty to deep time and geological processes. This gem began as olivine crystals in the upper mantle, crystallizing from magnesium iron silicate melts under high temperature and pressure, far beneath the Earths surface. Over geologic time, convective mantle processes and episodic volcanic activity transported pieces of that mantle material upward, entraining olivine crystals in rapidly ascending basaltic magmas. As those magmas cooled near the surface in the region that is now Tanzania, the olivine survived and was preserved as gem quality peridot. Subsequent uplift, erosion, and artisanal mining brought rough material to cutters, who fashioned this particular crystal into an emerald cut that respects the stone's natural color and internal structure. At The Natural Gemstone Company we emphasize provenance, scientific grading, and uncompromised natural quality, and this peridot exemplifies those values for buyers seeking a gemstone with both measurable attributes and a compelling geological origin.
