8.66 Ct. Cabochon Lapis from Afghanistan

This offering from The Natural Gemstone Company is one well finished example of lapis lazuli, presented as an opaque cushion shape cabochon weighing 8.66 carats. The gem measures 14.35 by 12.23 by 5.48 millimeters, and it displays a vivid, saturated blue that is consistent across the table. The cabochon cut has been executed to emphasize color depth rather than transparency, providing a rounded, domed surface that interacts with light to produce a soft, almost velvety appearance. The polish is excellent, producing a clean glossy surface with minimal surface abrasion. There has been no enhancement applied to this piece, and the lapis is reported to originate from Afghanistan, a source known for producing deep ultramarine material.

Lapis lazuli is a composite rock, dominated by the mineral lazurite, commonly accompanied by accessory phases such as pyrite and calcite. This specimen exhibits strong color concentration with only very minor natural variations in tone and a near absence of reflective pyrite speckling, which allows the rich blue to remain the primary visual feature. The stone sits at an appropriate height for ring and pendant work, with the 5.48 millimeter thickness providing substance and durability for bezel mounting. On the Mohs hardness scale lapis generally falls in the range of 5 to 5.5, and its specific gravity typically ranges around 2.5 to 3.0, values that inform handling and setting decisions. The cabochon form has been shaped to balance aesthetic mass and practical wearability while preserving the original rough material as fully as possible.

From a design perspective the dimensions and color intensity of this piece make it versatile for a variety of applications. It is well suited to a classic bezel set statement ring, a substantial pendant, or a pair of bespoke cufflinks. Because the surface is uniformly vivid, the lapis pairs effectively with both warm gold tones and cooler white metals depending on the design intent. Bezel settings are recommended for daily wear to protect the stone edges and to secure the cabochon profile, whereas prong settings can be used where the design emphasizes light reflection, provided the prongs are placed to minimize edge exposure. The opaque nature of the stone directs attention to surface color and polish, so design elements that frame rather than obscure the face will tend to showcase the piece most effectively.

Care and handling guidance is based on the material properties of lapis. Avoid exposure to harsh chemicals, acids, prolonged immersion in water, and ultrasonic or steam cleaning, as these can alter surface appearance and compromise the integrity of the stone. Clean with a soft cloth and, if necessary, a mild soapy water solution followed by thorough drying. Protect the lapis from hard knocks, and store it separately from harder gemstones to prevent abrasion. At The Natural Gemstone Company we can provide additional detailed photographs, measurements, and professional mounting recommendations to assist with the design and fabrication process. This lapis is offered in its natural state, with no enhancements recorded, and is accompanied by provenance information noting Afghanistan as the source region.
