LunaThe main stone: Topaz
Real topaz is an aluminium silicate with fluorine, Mohs 8, and it comes out of the ground colourless far more often than in any shade anyone wants. The warm sherry brown called imperial topaz is the rare one; the blue filling every high-street window is colourless material irradiated and then heated - a treatment that is stable, permanent, tested before sale and completely standard, and that belongs on the label. Ask, and a decent seller answers in a sentence.
The Scorpio correspondence is old and unusually stable between schools. Fixed water with Pluto as its modern ruler, the sign the tradition associates with whatever is kept below the surface, is given a stone that arrives clear and takes its colour from what was done to it. Apt or too neat, depending on temperament, but at least a reading with something behind it.
There is one physical quirk to settle before buying. Topaz has perfect basal cleavage - a plane along which it parts cleanly if struck at the wrong angle - so a Mohs 8 stone that shrugs off scratches can still lose a corner to a single knock on a door handle. That is not a fault in a particular stone; it is a property of the mineral, and it is dealt with by the setting.
Other Scorpio stones
Garnet is not one mineral either but a family, and the dark red almandine most people picture is only its commonest member - there are orange spessartines and a green tsavorite that can outprice a sapphire. For Scorpio the tradition wants the deep red end of the range, and it is by a wide margin the cheapest way onto this list.
Opal appears here too, and for a different reason than it does one sign earlier: not balance but change of state, a stone that shows a different colour to every person standing round the table. It is also October’s stone in the jewellery calendar, covering the first month of the sign, while November’s is topaz, covering the second. For once the two systems cover the same ground from opposite ends. Its handling rules are strict and are set out on the Libra stones page.
How to choose and wear it
Set the topaz low and it will be fine for decades. A bezel, a half-bezel or any protective mount absorbs the knock that cleavage would otherwise turn into a chip, whereas a high solitaire on a working hand is asking for trouble. Skip the ultrasonic cleaner and skip sudden temperature changes - warm water, mild soap, soft brush - and keep it away from harder stones in storage.
Between the three, the real question is how much you want to think about it. Garnet is hard, cheap and needs no plan whatsoever. Topaz needs a sensible setting and nothing else. Opal needs genuine care and returns the only stone here that looks different every time you glance at it. The tradition ranks none of them, and there is no wrong pick in the set.
Why sources disagree on the stones
Lists of stones for Scorpio differ from book to book and shop to shop - and that is normal: there is no single canon. The astrological tradition derived stones from ruling planets and elements, the jewellery tradition from the month of birth (the American birthstone table of 1912), and shops happily add to the lists whatever sits in the display case.
We fixed the overlap of the most common lists - the core that repeats most often. If another source names a different stone for you, neither list is wrong: pick the stone from the tradition that you actually like.

Frequently asked questions
What is the Scorpio birthstone?
The traditional main stone for Scorpio is the topaz, and the sign is also linked with garnet and opal. There is no single canon: lists vary between schools, so no pick from this set is “wrong”.
Scorpio runs across October and November - which month’s stone applies?
Both, depending on which chart is open. The jewellery calendar gives October opal and tourmaline and November topaz and citrine; the zodiac list gives the whole sign topaz, garnet and opal regardless of date. The overlap is unusually wide here, so most Scorpios end up with the same stone from either direction - the November page has the calendar version.
Is blue topaz natural?
Almost never in that shade. Natural blue topaz exists but is pale and scarce, while the sky blues, Swiss blues and London blues on sale are colourless topaz that has been irradiated and heat-treated. The colour is permanent, the material is checked for residual radioactivity before it can be sold, and it is not a fake - it is a treated natural stone, and honest tickets say as much.
Matching stones to zodiac signs is a tradition, not science: there is no single canonical list, and schools disagree. Stones do not heal and do not guarantee events - for health questions, see a doctor. A stone here is a symbol and a reminder, nothing more and nothing less.
