1.72 Ct. Green (Lime Green) Peridot from Tanzania

This listing describes a single transparent peridot, pear shape, weighing 1.72 carat, with dimensions of 8.99 by 7.06 by 4.57 mm. The gem is cut in a mixed brilliant style, combining a faceted crown that promotes strong light return with a pavilion geometry that preserves depth and fire. Color is a clear lime green with medium intensity, and clarity is graded slightly included when evaluated at eye level, which permits a clean visual appearance while confirming natural internal features. Polish is excellent, the stone shows crisp facet junctions and a smooth surface finish, and there has been no enhancement applied to the material. The peridot is sourced from Tanzania, a locality known for producing attractive green stones with good transparency and uniform color.

Durability characteristics are an important factor for jewelry design and daily wear planning. Peridot has a Mohs hardness of approximately 6.5 to 7, which places it below the most scratch resistant gemstones used in jewelry, and makes it more susceptible to surface abrasion when in contact with harder materials. The material is also more brittle than corundum or diamond, meaning that it can chip or fracture if subjected to sharp blows or repeated impact. Additionally, peridot can be sensitive to rapid temperature changes, so cleaning and handling practices that avoid thermal shock are advised. Despite these considerations, a well cut and well polished peridot such as this one offers good stability in settings that provide mechanical protection, and its optical performance is enhanced by the mixed brilliant cut which maximizes scintillation and perceived brightness.

To optimize longevity for daily wear, consider mounting strategies that protect the girdle and the more delicate pavilion and culet regions. Bezel settings, low profile surrounds, and designs that incorporate a halo of small accent stones all reduce the likelihood of direct impact on the stone edges and tip of the pear shape. If a prong setting is preferred for aesthetic reasons, ensure that prongs are substantial and secure, and that the profile of the setting does not leave the point overly exposed. Suitable placements for regular use include pendants and earrings, which minimize direct contact, or rings designed with protective metalwork for the stone. Routine maintenance recommendations include gentle cleaning with warm soapy water and a soft brush, avoidance of ultrasonic and steam cleaners because of potential sensitivity to thermal and mechanical stress, removal during heavy manual activity, and storage separate from harder gemstones to prevent scratching.

This peridot’s natural origin, lack of enhancement, and the presence of slight inclusions support its identification as a genuine, untreated gem, and contribute to its character and provenance. The medium intensity lime green color is a result of iron content in the olivine structure, and the Tanzanian source correlates with the bright, clean examples known from that region. Slight inclusions at eye level do not materially affect light performance in this particular specimen, thanks to the precise cutting and excellent polish executed on the crown and pavilion. For clients and jewelers seeking a responsibly sourced, untreated peridot for a custom piece, The Natural Gemstone Company can provide additional measurements, photographs, and setting recommendations to match design intent with practical wearability. Regular inspection of the mounting, ideally every six to twelve months, will help preserve the gem’s appearance and reduce the risk of loss or damage over time.
