Quick Answer: Crystal meanings are traditional beliefs about what a stone stands for, not facts about what it does. For the six stones on Akitai's charm bracelets, the sources checked without a stake in sales give a tradition for only a few: red jasper and aventurine in chakra lists, and sardonyx, a banded form of onyx, in Roman and Renaissance lore. There is no good evidence that stones treat any condition. Read meanings as symbols, and pick the stone you like.
Crystal meanings are about symbolism, and every list, including this one, is summarizing belief. Below are the six stones named on Akitai's charm bracelets: amazonite, howlite, aventurine, jasper, onyx and chrysocolla. You will find what each is traditionally associated with in the sources checked, where those ideas come from, and how hard each stone is, which matters more for wearing a bracelet than any meaning. For what bead colors are said to mean, see the color-by-color guide.
They are the qualities people in crystal-lore circles say a stone stands for. Wikipedia's crystal healing entry (checked October 2026) says practitioners select stones by color or by their believed metaphysical qualities, and that such lists are published in commonly distributed texts.
These are traditional and popular beliefs, not medical facts. A stone is not a treatment for any condition. WebMD says there is no good scientific evidence to support the uses claimed for crystal therapy, and Geology.com calls amazonite's claimed benefits anecdotal and not scientifically proven.
Less than most lists suggest. The table shows what the sources checked say, and where they say nothing it says so, rather than filling the gap. Hardness is on the Mohs scale, where 10 is the hardest.
| Stone | Tradition in sources checked | Mohs hardness |
|---|---|---|
| Amazonite | None found | 6 to 6.5 |
| Howlite | None found | 3.5 |
| Aventurine | Heart chakra (green form) | 6.5 to 7 |
| Jasper | Root chakra (red jasper) | 6.5 to 7 |
| Onyx | Sardonyx: courage, eloquence | 7 |
| Chrysocolla | None found | 2 to 4 |
The chakra rows come from Geology.com, which lists commonly used chakra stones and names the green form of aventurine for the heart chakra and red jasper for the root chakra. The onyx row comes from Wikipedia's onyx entry, which says the ancient Romans entered battle carrying sardonyx amulets engraved with Mars, assumed to bestow courage, and that in Renaissance Europe wearing sardonyx was assumed to bestow eloquence. Sardonyx is the red to brown banded variety, so this is not a tradition about black onyx itself.
The chakra idea is older than the stone lists. Wikipedia's chakra entry describes chakras as part of Hindu and Buddhist tantric yoga and meditation practices, with medieval Buddhist texts mentioning four or five, and says the rainbow colors and the links to gemstones were added later. So the color-and-stone system you meet in shops is a modern one, and no authority sets the matches.
It matters a lot. Amazonite, at 6 to 6.5, is best in earrings and pendants, says Geology.com, because it has two directions of perfect cleavage and can break if you knock a bracelet on something hard. Minerals.net says chrysocolla's low hardness limits its use in jewelry, and the Handbook of Mineralogy puts howlite at only 3.5. Onyx, at 7, and jasper and aventurine, at 6.5 to 7, are among the harder ones, according to Minerals.net's pages on onyx, jasper and aventurine.
That describes the minerals, not any one bracelet. Akitai's Warranty page says to keep jewelry dry, away from perfume, lotion and cleaners, and to store it in a cool, dry place out of direct sun.
Choose the meaning you enjoy, or none at all, then check that the stone suits a bracelet. Two stones can look alike on a wrist and behave very differently. Amazonite is a mid-hardness feldspar, and chrysocolla is soft. If you want a harder stone, onyx, jasper and aventurine all rate 6.5 to 7 or above in the table.
Some stones have a history of use without a recorded meaning. Wikipedia says amazonite has been used in jewelry for more than three thousand years, from archaeological finds in Egypt and Mesopotamia, yet is not mentioned by any ancient or medieval source. Minerals.net says onyx has been used in jewelry and carving since antiquity.
Akitai's charm bracelet collection has four stretch bracelet listings, each named for its stones: amazonite and howlite, aventurine, jasper and chrysocolla and onyx. Since Akitai is the brand behind this site, they are our own products. The product pages name the stones, and this guide takes the names as given.
The six covered here are amazonite, howlite, aventurine, jasper, onyx and chrysocolla. Other well-known stones, such as amethyst and rose quartz, are outside what Akitai sells.
No. Meanings are traditional beliefs, and WebMD says there is no good scientific evidence for the medical uses claimed.
Because the sources checked give no tradition for them. No authority sets crystal meanings, and this guide does not fill gaps.
Yes. No authority sets them, so wording and emphasis vary, and some stones have no recorded tradition at all.
The chakra idea is old, from Hindu and Buddhist tantric yoga and meditation practices. The rainbow color scheme and stone links were added later.
Chrysocolla, at about 2 to 4 on the Mohs scale, followed by howlite at 3.5.
