More couples are choosing a sapphire, a spinel or an emerald over a white diamond. Here is which colored stones can be worn every day, how to set them, and what to ask before you choose.
An engagement ring is worn every day for decades, so the stone has to survive doorframes, gym bars and dishwater. Sapphire and ruby are the safest colored choices, spinel is close behind, and softer stones such as emerald, tourmaline and zircon can work in a protective setting if you're willing to be a little careful.
Choose the color you love first, then the stone that gives you that color with the durability your life needs.
This is not a passing mood. In INSTORE's 2026 Big Survey of independent jewelers, colored-gemstone engagement rings were among the styles jewelers named as coming next, alongside bezel settings (INSTORE). Jewelers in the same survey describe colored stones, "especially sapphires," as gaining ground with couples (INSTORE).
The design world agrees. At the American Gem Trade Association's 2026 Spectrum Awards, the engagement ring category went to a platinum ring centered on a 4.5-carat blue zircon, and the bridal category to a 5.32-carat Paraíba tourmaline. Blue was the dominant color of the year (JCK). The award for the year's signature red went to a ring set with a 6.21-carat unheated red spinel (JCK).
Two properties decide whether a stone will look the same in thirty years. Hardness is resistance to scratching, measured on the Mohs scale, where diamond is 10. Everyday dust contains quartz at 7, so anything softer than 7 slowly dulls. Toughness is resistance to chipping and cracking from a knock, and it is why a hard stone can still be fragile.
| Stone | Mohs | Every day? | Good to know |
|---|---|---|---|
| Sapphire | 9 | Yes | Hard and tough. Blue, pink, yellow, green, white, and the pink-orange padparadscha. |
| Ruby | 9 | Yes | The red form of sapphire, with the same durability. |
| Spinel | 8 | Yes | Reds, pinks, lavenders and cobalt blues. Rarely treated. |
| Aquamarine, morganite | 7.5–8 | Yes, with care | Pale blue and peach-pink. Clean stones that show wear less than emerald. |
| Emerald | 7.5–8 | With care | Almost always included, so it chips more easily. Best in a bezel. |
| Tourmaline | 7–7.5 | With care | Every color, including Paraíba's neon blue-green. Protect the corners. |
| Zircon | 6–7.5 | With care | Natural zircon (not cubic zirconia) with real fire, but its facet edges wear. |
| Tanzanite, opal | 5–7 | Not ideal | Beautiful, but better in a pendant or earrings than a ring worn daily. |
Hardness ranges are the standard gemological values. A stone's own inclusions and cut affect its toughness too.
Prongs show the most stone and let light in from the sides, which is how a sapphire or spinel looks its brightest. They suit the tough stones. A bezel, a thin rim of gold around the whole stone, covers the girdle and corners where chips start. It's the natural choice for emerald, tourmaline and zircon, and it gives any ring a smooth, modern profile that won't catch on knitwear.
Metal color changes the stone, too. Yellow gold warms a ruby or a pink sapphire, while white gold or platinum keeps a blue sapphire or an aquamarine cool and crisp. If you're unsure, ask to see the stone against both.
In the commission form, choose Colored gemstone, or My own stone if you already have one, and tell us the color you have in mind. We'll match the stone and the setting to how the ring will be worn. The engagement rings page shows the kind of work we do, and the materials guide covers gold and platinum. For budget, see what a custom engagement ring really costs.

Sapphire, for most people. At 9 on the Mohs scale it is second only to diamond, it is tough as well as hard, and it comes in nearly every color. Ruby is the same mineral in red. Spinel, at 8, is the strongest alternative.
You can, with care. Emerald is hard enough (7.5 to 8) but almost always included, which makes it more likely to chip from a knock. A protective bezel setting and taking it off for the gym, gardening and cleaning make daily wear realistic. See care & maintenance.
Softer or more brittle stones such as emerald, tourmaline and zircon benefit most, because a bezel covers the edge where chips start. Sapphire and ruby are tough enough for prongs, which show more of the stone and let in more light.
Heating is a long-standing, stable treatment used on most sapphires on the market, and it does not affect durability. It does affect price: an unheated stone of the same color costs more. Ask for treatment to be disclosed, and for an important stone, a report from an independent gem lab.
