CABOCHON gemstones are a distinctive category of polished gemstones that exhibit a smooth, rounded, and polished convex surface, as opposed to the traditional faceted gemstones. The term "cabochon" originates from the French word "caboche," meaning a knob or small dome.

These gemstones are shaped and polished into a smooth, rounded, and often domed shape without any facets, resulting in a polished, curved surface that showcases the stone's natural colors, patterns, and inclusions. The absence of facets distinguishes cabochons from their faceted counterparts, allowing for a different play of light and emphasizing the stone's natural characteristics.

Cabochons can be crafted from various types of gem materials, including but not limited to precious and semi-precious stones like opal, turquoise, moonstone, jasper, onyx, and many others. They are frequently used in jewelry making, featuring prominently in rings, pendants, earrings, and bracelets, as their smooth surface allows for unique settings and designs that highlight the stone's individual beauty.

The appeal of cabochon gemstones lies in their captivating natural patterns, colors, and phenomena like iridescence or chatoyancy, which are accentuated by the smooth, polished surface. Their versatility makes them a popular choice for both contemporary and vintage-style jewelry designs, appealing to those seeking distinctive and eye-catching pieces that emphasize the stone's inherent characteristics.
