Stoney Bracelets
Since 2019 we have been making handmade gemstone bracelets for 20,000+ customers. Every stone is hand-selected in our own studio.

Type "coral bracelet" into a search bar and most people picture red or pink. Our coral is blue. It is a soft, denim-blue bead with a raw, porous surface, and that surprises anyone who was counting on red. Below you'll read what this material is, why it can be blue, how to recognize it and what to do to keep it looking good. The wider range is in our gemstone bracelets.

What coral actually is

Coral is not a rock that grew in the earth. It is the calcium skeleton of a reef coral: an organic material made of calcium carbonate. That explains two things you notice right away. The surface is porous, with tiny holes where life once sat in the skeleton, and a fine, fibrous pattern runs across the bead, a bit like wood. You won't find polished glass like obsidian here.

The blue tone is in the material itself. In our photos it is a muted denim color, sometimes with a lighter or even white bead in between. That comes with natural material: no two beads take on the same shade.

Four things to know before you wear one

1
The holes belong there
The pores are not a production flaw. They are proof that the material grew, and they differ from bead to bead.
2
It's soft
At 3.5 to 4 on the Mohs scale, coral is softer than obsidian and much softer than quartz. It scratches more easily and can get damaged against a hard edge.
3
It's matte
The bead absorbs light instead of reflecting it. That gives it a laid-back look that never comes across as too polished.
4
It reacts to acid
Calcium carbonate is eaten away by acids. So perfume, sweat and chlorine are no friends of coral.

How to recognize real coral

Look at the surface, not just the color. Real coral has irregular holes and a fine fibrous pattern that runs differently on every bead. A bead with exactly the same shade everywhere and a smooth, glossy surface points more toward a dyed or cast material.

Also pay attention to temperature and weight. Coral feels cool, warms up slowly and has a dry, slightly rough touch. A plastic bead feels warmer and lighter.

Coral next to other matte stones

Matte, porous or understated stones look alike on paper, but they wear very differently. For more on the finish itself, read matte versus polished obsidian.

Stone Look Character
Blue coral Denim blue, matte, small holes and fibrous pattern Raw and relaxed, soft in color
Lava stone Dark gray to black, rough and porous Rugged and neutral, no color
Matte lapis lazuli Deep blue, matte, sometimes with light veins Deeper and more serious than coral

Wearing it without the color shouting

Blue coral is a calm color. It works as the only accent with a white shirt, a gray sweater or jeans, and it sits well with other shades of blue without clashing. In the photo below you can see how lighter, porous beads behave next to deeper blue beads on a dark, charred piece of wood: the tone stays within the same family and the surface makes the difference.

Want contrast instead? Pick a bold partner. In the next photo, blue coral sits next to a green stone with purple spots: the coral stays the calm base and the other bracelet takes care of the exclamation mark.

With a silver accent

Want coral with something extra? Our Poseidon Silver+ combines blue coral with rhodonite and a silver bead. You'll find it among the bracelets with silver. In the photo the blue of the coral is easy to spot, the pink rhodonite adds warmth and the silver brings a cool shine.

Caring for a soft stone

What Do this Avoid this
Cleaning Wipe with a soft, dry cloth Water, soap and abrasives
Perfume and sweat Take the bracelet off before you put on perfume Spraying your wrist with the bracelet on
Pool and sports Take it off and store it separately Chlorine, salt water, heavy work
Putting it on Roll it gently over your hand Stretching the cord roughly
To be honest

We only carry blue coral, in 8mm. No red or pink coral and no 6mm. If you're looking for red, this stone isn't what you have in mind. We'd rather tell you now than after you order.

Quick verdict

Choose coral if you want a calm blue bead with a raw, matte surface. Keep its softness and acids in mind, and don't wear it for sports or in the pool.

Frequently asked questions

What color is coral at Stoney Bracelets?+
Our coral is blue: a soft, denim-blue shade with a matte finish. We don't carry red or pink coral. People searching for a coral bracelet often expect red, so take a close look at the product photos before you order.
Is coral a real stone?+
Strictly speaking, no. Coral is an organic material: the calcium skeleton of a reef coral. In jewelry it is cut and drilled into beads just like natural stone, and in practice it is counted among the gemstones.
How hard is coral?+
Coral sits at roughly 3.5 to 4 on the Mohs scale. That is noticeably softer than quartz, which sits at 7. So it scratches more easily and doesn't handle hard knocks.
Are the little holes in the beads a defect?+
No. The porous structure is part of coral. If you see the same holes in the same spot on every bead, that is actually a reason to look more critically. With natural material, every bead is different.
What sizes does the Coral bracelet come in?+
The Coral Stones bracelet has 8mm beads and is available in Small, Medium, Large and X-Large. The size chart helps you pick the right size for your wrist.
Can I wear coral every day?+
Yes, as long as you keep its softness in mind. Take it off for sports, heavy work and before you put on perfume or go swimming. Wipe it afterwards with a soft, dry cloth.
