Bloodstone does not sound like a jewelry stone. The name puts people off, and the historical legend — that the red spots formed from drops of blood falling on green jasper at the crucifixion — does not help. But stand a well-cut bloodstone cab next to an onyx, and the difference is immediate: a deep, mossy, almost forest green, flecked with rust-red spots that catch the light like embers. It is one of the most forgiving, most wearable colored stones in the chalcedony family, and it is criminally underused in modern design.

What it actually is

Bloodstone, also sold under its older Greek name heliotrope, is a dark green, microcrystalline chalcedony (quartz) containing small, red to brownish spots of iron oxide or red jasper. The green base is often colored by chlorite or amphibole particles. Most commercial material comes from India, with historic sources in Brazil, Australia, and the United States. It is a Chalcedony, in the same family as agate, carnelian, and chrysoprase — which is to say, tough, stable, and easy to live with.

Hardness and wearability

At 6.5 to 7 on the Mohs scale, bloodstone sits right in the sweet spot for daily-wear rings. It has no prominent cleavage, it will not crack under ultrasonic cleaning, and it is not sensitive to light, heat, or household chemicals. We set it with confidence in signet rings, men's bands, and everyday pendants in a way we would never set, say, a tanzanite. If you want a colored stone you never have to think about, this is one of the shortest lists.

How it is cut

Bloodstone is almost always cut as a cabochon, never faceted. The whole point is the pattern: the deep green body and the scattered red flecks. A cutter will orient the stone so the most interesting cluster of red sits where the eye lands, and they will often cut it as an oval or a cushion rather than a round, because the irregular shape suits the irregular spotting. We see it in two basic grades: solid, even green with a few well-placed flecks, and heavily spotted material that looks more like a pattern than a stone. Both have their fans; the first reads as formal, the second as rustic.

Is it dyed?

Honest question, because chalcedony gets treated constantly. Some commercial bloodstone on the market is artificially dyed to deepen the green or make the red spots more dramatic. Natural, untreated material has a slightly softer, more organic look — the green tends to vary, and the red flecks are irregular rather than uniform. At our bench, if we cannot tell the origin of the color, we say so. It does not need to be a deal-breaker, but you should know what you are paying for. For more on how treatments change what a stone is worth, our colored gemstone buying guide walks through the checklist.

Wearing and care

Bloodstone takes cleaning in stride. Warm soapy water, a soft brush, even the ultrasonic are all fine. It should still be kept out of direct, prolonged sunlight if you care about preserving the exact tone, and it should not be tossed loose in a jewelry box with diamonds, because even at 7 on Mohs it will still pick up fine scratches against harder stones. For storage logic across your whole collection, see how to store jewelry to prevent scratches.

Why it deserves a comeback

Bloodstone is the March alternative birthstone (alongside aquamarine), which means it gets dusted off once a year and forgotten. That is a shame. Its deep green works in yellow gold, rose gold, and platinum equally well, and the red fleck gives a designer a natural accent to build around. We have set it as a men's signet, as a women's statement pendant, and as the center of a stackable trio. If you want a stone that is recognizable up close but never looks like anyone else's ring, bloodstone is a genuine sleeper pick.

Historical weight, modern wear

Bloodstone was one of the signature stones of the medieval and Renaissance lapidary tradition, carved into intaglios and signets long before the great emerald and ruby trades opened up. That history shows in how it wears: it is a stone that already looks patinated at the bench, which is why it pairs so naturally with slightly brushed, hand-finished metal rather than a mirror polish. We often match a bloodstone cab to a matte or satin-finished shank, because the contrast between the soft green stone and the subtly textured gold does more than either finish alone. It is also one of the few colored stones we are happy to recommend for a pinky signet, a men's band, or a unisex pendant — the deep green reads as serious without feeling masculine-coded the way onyx sometimes does. For clients who want a birthstone alternative that no one else at the office will be wearing, bloodstone is the easiest recommendation we make.

30% T/T deposit with the balance against the bill of lading. This protects both sides on first orders and can move to net terms after a track record.

What is your normal reject rate?

3–5% under 10x loupe inspection for cast and set pieces. Defective units are replaced free in the next shipment.

Where is the factory located?

Wuzhou, Guangxi, China—the core lab-grown and moissanite manufacturing cluster. Shipments go via Guangzhou or Shenzhen ports.
