Cabochon gemstones are polished with a smooth domed top instead of facets. This cut shows off glow, pattern and special effects, which is why opal, moonstone, star sapphire, cat’s eye, turquoise and agate are so often cut this way.
How to choose a cabochon
- Check the dome: it should be even and smooth, without flat spots.
- Centre the effect: a star or cat’s eye line should sit in the middle of the dome.
- Look at the base: a very thick base adds weight without adding beauty.
- Pick a bezel setting: it holds the edge securely and protects softer stones.
- Expect softer stones: many cabochon gems, like opal and turquoise, need gentle care.
