What does domed mean in jewellery?

Definition
Domed describes a surface that is smoothly rounded and convex, like the top half of a sphere, and in jewellery you see it in two main places. A domed gemstone is one cut as a cabochon, with a smooth curved top rather than facets, which is the traditional form for stones like moonstone, star sapphire and turquoise. A domed ring band has a gently curved, rounded profile across its width rather than a flat top, which many people find very comfortable and classic.
Frequently asked questions
- What is the difference between a domed and a flat ring band?
- A domed band has a gentle outward curve across the top, so when you look at it from the side it is rounded. A flat or court band has a level surface. Many people find domed bands more comfortable as they sit smoothly against the finger.
- Which gemstones are cut domed?
- Stones cut with a smooth domed top are called cabochons. Common examples include moonstone, opal, turquoise, star sapphire, star ruby and many agate varieties. The domed shape shows off optical effects like adularescence and asterism best.
- Is a cabochon the same as a domed stone?
- Yes, a cabochon is a stone with a flat base and a smooth, domed top, which is what domed means in gemstone cutting. The word cabochon comes from French and describes exactly that polished, curved form.
