Birthstone Guide
Your birthstone, by birth date — not just birth month
The traditional list gives twelve stones for eight billion people. Your full birth date gives something far more specific: a five-element profile, and a bracelet built from it — hand-strung to order in Taiwan and shipped worldwide.
Birthstones by month
The traditional stone for each month, and — where the traditional stone is a precious gem we don't work with — the natural crystal we use instead. We'd rather tell you than let you find out at checkout.
| Month | Traditional | Our natural crystal | Note |
|---|---|---|---|
| January | Garnet | Garnet | Deep red — tradition links it to vitality and steady drive. |
| February | Amethyst | Amethyst | Purple quartz — long associated with clarity of mind. |
| March | Aquamarine | Aquamarine | Sea-blue beryl — a stone of safe passage in folklore. |
| April | Diamond | Clear Quartz | We don't sell diamonds. Clear quartz is the natural-crystal stand-in. |
| May | Emerald | Green Phantom Quartz | For green symbolism without the emerald price tag. |
| June | Pearl / Moonstone | Moonstone | Soft sheen — tied to cycles and intuition in tradition. |
| July | Ruby | Red Agate | We don't sell rubies. Red agate carries the warm-red symbolism. |
| August | Peridot | Amazonite | Fresh green-blue — associated with candid expression. |
| September | Sapphire | Blue Phantom Quartz | Blue depth in a natural quartz form. |
| October | Opal / Tourmaline | Tourmaline | Tourmaline comes in many colours — we stock several. |
| November | Topaz / Citrine | Citrine | Warm yellow — a classic symbol of abundance. |
| December | Turquoise / Tanzanite | Terahertz | Cool metallic sheen as the winter stand-in. |
Birthstone associations are cultural traditions that vary by country and era. They carry symbolic meaning only — no medical or scientific effect is claimed.
Why your birth month is only half the story
If you were born in June, the list hands you a moonstone — and so does it for everyone else born that month. It's a rough map, and it was never meant to be more than that.
The Chinese four-pillars tradition starts from the same place — your birth — but reads far more of it. Your year, month, day and hour each convert into a pair of calendar symbols; the balance of the five elements across those pairs is what the reading is built on. Same idea as a birthstone. Much higher resolution.

Questions
What is my birthstone by birth date, not just birth month?
The birthstone list assigns one stone per calendar month — about twelve outcomes for the whole world. Using your full birth date (year, month, day and, if you know it, hour) produces a far more specific profile. We use the Chinese five-element system: the birth date is converted into four pillars, the balance of Wood, Fire, Earth, Metal and Water is calculated, and stones are matched to the elements worth strengthening. It is a cultural framework, not a medical or predictive one.
Is this the same as my birth chart?
It is the same idea from a different tradition. A Western natal chart maps planets at your moment of birth; the Chinese four-pillars system maps the calendar cycle of your birth into five elements. Both start from birth data and both are read symbolically. If you already choose crystals by your birth chart, this will feel familiar.
Do I need my birth time?
No. The calculation works with date only; adding the hour simply refines it. If you don't know your birth hour, the tool still produces a full recipe.
Are these real natural crystals?
Yes — natural, undyed and non-synthetic, with sourcing checks. We can also arrange third-party identification certificates through Taiwanese gemmological laboratories (fee applies), and you are welcome to have any piece independently tested.
Do you ship outside Taiwan?
Yes. Every order is hand-strung to order in our Taichung studio and shipped worldwide by SF Express — roughly 1–2 business days to Hong Kong, 2–5 to Singapore and Malaysia, and standard international service to the US, Canada, Europe, Japan, Korea and Australia. Prices display in your local currency and you pay online by card.
What do the stones actually do?
Nothing medical, and we won't claim otherwise. Crystals are natural minerals worn as jewellery; the meanings attached to them are cultural and symbolic. What you get is a piece connected to your own birth data, with a written record of why each bead is there.
Start with your birth date
Free, takes about a minute, and you can change every bead afterwards.
