What Is a Cabochon? A Complete Guide to Cabochon-Cut Gemstones
If you've spent any time browsing gemstone jewelry, you've almost certainly come across the word cabochon — and you've probably seen far more cabochons than you realize. From the smooth, domed turquoise in a silver ring to the polished agate pendant around someone's neck, the cabochon is one of the oldest and most beloved ways to cut a gemstone. In this guide, we'll walk through exactly what a cabochon is, how it's made, the most popular shapes, and why so many collectors and jewelry makers prefer it over faceted stones.
What Is a Cabochon?
A cabochon (often shortened to "cab") is a gemstone that has been shaped and polished into a smooth, rounded form rather than cut with flat, angled facets. The term comes from the French caboche, meaning "head" or "knob," a nod to the dome-like shape. Unlike faceted stones, which rely on precise angles to reflect and scatter light, a cabochon is prized for its color, pattern, and the way light glows softly across its polished surface.
Cabochons are typically flat on the back and gently domed on top, though shapes and dome heights vary widely depending on the stone and the cutter's design. This cut has been used for thousands of years — long before faceting techniques existed — and remains the standard choice for opaque and semi-translucent stones like turquoise, jasper, agate, and lapis lazuli, where color and pattern matter more than brilliance.
How a Cabochon Is Made
Every cabochon starts as rough material — a slab or chunk of natural stone. The process, refined over generations in workshops like ours in Jaipur, generally follows four steps:
- Slicing the rough — The rough stone is sliced into flat slabs of workable thickness using a diamond lapidary saw.
- Marking the shape — The cutter studies the slab's natural color and pattern, then marks out the shapes that will make the best use of it — ovals, hearts, pears, freeforms, and more.
- Cutting the marked shapes — Each marked shape is cut free from the slab using a trim saw, leaving a rough blank ready for shaping.
- Grinding and polishing — The blank is ground against progressively finer diamond wheels to create the dome, then polished to a glassy shine. The back is typically finished flat for setting into jewelry.
Every piece is hand-shaped, which means no two cabochons — even from the same slab — are ever perfectly identical. That's part of what makes them collectible.
Popular Cabochon Shapes
While the classic oval is the most common cabochon shape, cutters shape stones into dozens of forms depending on the rough material and intended use:
- Oval — the most versatile and widely used shape, suited to rings, pendants, and earrings
- Round — a classic, symmetrical shape often used for statement pieces
- Pear / Teardrop — an oval with a pointed tip, popular for pendants
- Heart — a romantic shape favored for gifts and sentimental jewelry
- Cushion — a squarish shape with soft, rounded corners
- Freeform — an organic, irregular shape that follows the natural contour of the rough
- Marquise — a narrow, pointed-oval shape (also called navette)
- Trillion — a rounded triangular shape
Cabochon vs. Faceted: Which Is Better?
Neither cut is objectively "better" — they simply serve different purposes. Faceting is used on transparent stones (like amethyst, citrine, or topaz) to maximize brilliance and sparkle through light refraction. Cabochons are used on opaque or semi-translucent stones where the goal is to showcase natural color, banding, matrix, or inclusions rather than sparkle. Materials like turquoise, jasper, agate, and composite stones are almost always cut as cabochons because faceting would do nothing to enhance them — their beauty lies in pattern and color, not light reflection.

Caring for Your Cabochons
Most cabochons are relatively low-maintenance, but a few habits will keep them looking their best for years: store them away from harder gemstones to avoid scratching, clean gently with a soft cloth and mild soap, and avoid ultrasonic cleaners or harsh chemicals, especially on dyed, stabilized, or softer stones.
