Simply put, a Cabochon (or "Cab" for short) is a gemstone that is not "cut" to create facets, but rather "polished" to a smooth finish.

It possesses two main characteristics:

Top Side: The upper surface is always convex (dome-shaped) or rounded.

Bottom Side: The underside is completely flat.

Its advantage in jewelry?

Cabs lack "facets" (glass-like cut surfaces); consequently, they beautifully showcase the stone's natural patterns, colors, and textures. They are quite easy to fit into bezel settings, making them the preferred choice for crafting rings, pendants, and cufflinks. https://armoniagems.com/blogs/news/what-is-a-cabochon
