Loose Cabochon Cut Gemstones

Certain precious stones naturally display their best qualities in cabochon form, particularly those with special optical effects like asterism or chatoyancy that require the smooth, domed surface to properly manifest. Opaque high-quality gems like fine turquoise and lapis lazuli showcase their natural beauty through the smooth cabochon surface rather than faceting, which would diminish their unique color patterns and aesthetic appeal. Additionally, materials with inclusions that might detract from a faceted stone often become distinctive character elements in well-executed cabochon cuts.

The value primarily depends on the gemstone’s inherent worth, color intensity, and clarity, with exceptional examples commanding prices comparable to their faceted counterparts. A flawless cabochon with exceptional polish and perfect symmetry commands higher prices, particularly in rare materials like fine jadeite or star sapphires. For star stones, the strength and definition of the phenomenon significantly impacts cost, with perfectly centered, sharp rays increasing value exponentially in natural, untreated specimens.

While faceted gems typically dominate investment discussions, rare cabochon-cut specimens can be worthwhile investments, particularly when they showcase phenomena impossible to display in faceted cuts. Star sapphires, fine jadeite, and black opals in cabochon form have consistently appreciated in value, sometimes outperforming their faceted counterparts in premium quality examples. Conflict-free, natural cabochons of exceptional quality maintain their worth over time, especially when accompanied by prestigious laboratory certification confirming their genuine character and documenting any special optical properties.
