Collection: March Birthstone Jewelry

Two stones, one month

March carries both aquamarine and bloodstone, and they could hardly be less alike. Bloodstone is the traditional, older assignment. Aquamarine is the modern one, and the one most people now mean when they say "March birthstone". Both are correct. Nobody is grading you.

Aquamarine

Aquamarine is beryl — the same mineral family as emerald, coloured by iron instead of chromium. That makes it hard (7.5–8 on Mohs), which is excellent news for rings, and it comes in a narrow, recognisable range: pale sea-blue through to a slightly greener seawater tone. Deeply saturated aquamarine is rare and priced accordingly; most jewellery aquamarine is pale, and pale suits it.

Its reputation is calm under pressure. Sailors carried it for safe passage, which is where the name comes from. In modern crystal terms it sits at the throat — clear speech, honest answers, saying the thing you actually meant rather than the thing that came out. A useful stone for anyone who rehearses conversations.

Bloodstone

Bloodstone is chalcedony: dark green jasper flecked with iron oxide red. It looks like nothing else, and it is the opposite of pretty — which is exactly why the people who like it, like it a lot. Around 6.5–7 on Mohs, opaque, and best cut as a cabochon or a bead rather than faceted.

It has always been the courage stone. Grounding, physical, associated with endurance and with getting through the difficult stretch rather than avoiding it. If aquamarine is the stone for speaking clearly, bloodstone is the stone for still being standing afterwards.

Genuine, lab-created and look-alikes

Both stones are affordable in genuine form, but pale blue glass and dyed quartz both get sold as aquamarine, and green-and-red resin gets sold as bloodstone. Every listing here states which it is: genuine, lab-created, or a look-alike standing in for the colour. A look-alike is never described as the real stone.

Aquamarine is often heat-treated to remove a green cast and push it bluer. This is standard industry practice, permanent, and not a defect.

Choosing between them

Colour usually decides it. Aquamarine is cool and reads as jewellery in the traditional sense — it works in silver, it works for weddings, it works for someone who wears mostly blues and greys. Bloodstone is earthy and reads as something you found rather than bought; it suits gold, leather, and people who prefer their jewellery to look like it has a history.

If you're buying a gift and cannot guess, aquamarine is the lower-risk choice. Care for both is the same: warm water, mild soap, no ultrasonic. Details in the crystal care guide, and the longer read is in the March birthstone guide.
