1.37 Ct. Pink Spinel from Tanzania

This listing describes a single transparent pink spinel weighing 1.37 carat, presented in a cushion shape with exact dimensions of 8.35 x 5.73 x 3.16 mm, supplied by The Natural Gemstone Company. The gem has been faceted in a mixed brilliant style, and it displays a medium color intensity that reads as a true pink in natural light. Clarity has been evaluated at eye level as slightly included, and the stone benefits from an excellent polish that enhances its surface luster and the precision of its faceting. The spinel is natural and untreated, there has been no enhancement applied, and the material originates from Tanzania, a source known for producing well colored spinel specimens.

The cutting style is a mixed brilliant faceted cushion, a design chosen to balance brilliance with a broad, elegant outline that is well suited to both classic and contemporary settings. The mixed brilliant faceting concentrates flash and scintillation towards the center of the table while maintaining solid brilliance along the pavilion facets, producing pleasing light return for a stone of this size. The cushion silhouette provides soft rounded corners and a substantial face up area, which maximizes perceived size and color presence at 8.35 mm by 5.73 mm. The excellent polish contributes to crisp facet junctions, and the slightly included clarity grade means that there are internal features visible under careful inspection at close range, however these do not dominate the gem visually when viewed in typical jewelry applications.

Durability and day to day suitability are important considerations for any gemstone, and spinel is a robust choice with a Mohs hardness of 8. This places spinel above many common gem materials, and below corundum varieties such as sapphire and ruby which are rated at 9, and substantially below diamond which is rated at 10. In practical terms a spinel at hardness 8 resists scratching from most household materials, and it holds up well to regular wear when set in rings, pendants, or earrings. Compared to a 9 on the Mohs scale, the difference is modest in everyday use, however care should be taken to avoid contact with materials of higher hardness that could abrade the stone over time. Because this particular spinel is slightly included, mechanical impact or abrasive environments should be avoided, and protective setting styles such as bezel settings or lower profile prongs are recommended for pieces intended for frequent wear.

Care guidance for this natural unenhanced spinel favors gentle cleaning methods, using warm soapy water and a soft brush to remove oils and residue, followed by careful rinsing and drying. Ultrasonic or steam cleaning may be acceptable for many spinels, however the presence of eye visible inclusions suggests prudence, and The Natural Gemstone Company recommends discussing ultrasonic cleaning with a qualified jeweler before proceeding. Spinel is generally stable to heat and common chemicals, yet sudden thermal shock and aggressive chemical exposure should be avoided. For setting recommendations, consider bezel or partial bezel mounts to protect the girdle and corners, or well maintained prongs if a more open look is desired, noting that the cushion profile and mixed brilliant faceting will display best when the table is unobstructed and the pavilion is allowed to transmit light freely. Documentation of the gem details including carat weight, dimensions, shape, cut, clarity grade, color intensity, polish, treatment status, and origin is available upon request from The Natural Gemstone Company, and this information supports both valuation and appropriate handling for use in finished jewelry, design projects, or private collections.
