What Are Cabochon Cut Gemstones?

Cabochon cut gemstones feature a polished, rounded top with a flat or slightly domed base instead of facets. This classic gemstone cut is used to emphasize color, transparency, and special optical effects such as star stones, chatoyancy, and color play.

Popular Cabochon Gemstones

Many gemstones are traditionally cut as cabochons. Popular choices include opal cabochons with vibrant color play, moonstone cabochons displaying adularescence, turquoise cabochons prized for their rich color, and star sapphires that show asterism.

Cabochon Stones for Jewelry

Cabochon stones are widely used in rings, pendants, bracelets and earrings. Their smooth surface and bold appearance make them ideal for bezel settings and statement jewelry pieces.

Unique Optical Effects in Cabochon Gems

The cabochon cut is essential for gemstones that display optical phenomena. Star sapphires, star rubies, cat's eye chrysoberyl and many moonstones require the cabochon shape to reveal these special visual effects.

Loose Cabochon Gemstones for Collectors

Loose cabochon gemstones are popular among collectors because they often showcase natural patterns, inclusions, and color zoning that would be hidden in faceted stones. Each gem has its own distinctive appearance.

Choosing the Right Cabochon Gemstone

When selecting a cabochon gemstone, consider color saturation, surface polish, symmetry and dome height. High quality cabochons have even curvature, excellent polish and vibrant natural color.

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.
