How Much Is Bloodstone Worth?
A dark green chalcedony flecked with red — the classic March birthstone. Historic, hard-wearing and inexpensive, with value decided by even green colour and vivid, well-placed “blood” spots.
Bloodstone is one of the oldest ornamental gems still in everyday use. A member of the chalcedony family — the same broad quartz group as carnelian, chrysoprase and onyx — it pairs a dark green body with scattered red flecks, and that vivid contrast has made it a favourite for signet rings, carved seals and the March birthstone for centuries. It is opaque, hard-wearing and inexpensive, which makes it an easy, characterful choice for a masculine ring or a piece with history.
Because it is common and cut mostly as cabochons, beads and carvings, its price turns on appearance rather than carat weight. The stones people prize show a rich, even green with crisp, blood-red spots placed attractively across the surface; the ones to leave behind are pale, greyish or blotchy, with dull or barely-there markings. Knowing that difference is almost the whole of buying bloodstone well.
Key takeaways
- It is chalcedony, a cryptocrystalline quartz — green jasper or chalcedony carrying red iron-oxide (hematite) spots, hence the name bloodstone.
- Colour and spots decide value. A deep, even green base with bright, well-distributed red flecks is worth far more than dull, blotchy material.
- Sold by the piece, not the carat. As an opaque cabochon or carving stone, it is priced on looks and workmanship rather than weight.
- Tough and everyday-friendly at about Mohs 6.5–7, well suited to rings, signets and beads.
- A traditional March birthstone, long used for seals and intaglios — antique carved pieces can be genuinely collectible.
What bloodstone actually is
Bloodstone, or heliotrope, is a mineral aggregate: a cryptocrystalline mixture of quartz that occurs mostly as opaque green jasper, and sometimes as more translucent green chalcedony, carrying inclusions of red jasper or hematite. The green comes from included minerals such as chlorite or amphibole, while the characteristic red spots and streaks are iron oxide that can look strikingly like droplets of blood. Hardness sits around 6.5 to 7 with no cleavage, so it is durable and takes a good polish — part of why it has been engraved into seals and signets since antiquity.
The classic material comes chiefly from the Deccan Traps of India, which remains the main commercial source, with other deposits in Brazil, Australia, China, Madagascar, the United States and parts of Europe. Some Indian bloodstone also carries flecks of white, yellow or blue chalcedony alongside the red. As a member of the wider chalcedony family, it sits beside carnelian and chrysoprase, and like them it is abundant and affordable rather than rare.
How it is valued
Appearance drives everything. The most valued bloodstone has a deep, even green base — not pale, grey or patchy — carrying bright, well-defined red spots that are pleasingly distributed rather than clustered in one dull smear. A clean, high polish and the absence of cracks, pits or chalky grey zones matter, as does the cut: a symmetrical cabochon or a crisply engraved seal shows the material at its best. Because it is opaque and sold by the piece, carat weight counts for little on its own; a small, vivid stone easily outperforms a larger, muddier one. For antique or carved pieces, the quality and age of the workmanship can matter as much as the stone.

Typical fair prices
| Grade | Indicative fair price | Notes |
|---|---|---|
| Commercial beads & tumbles | $1–$3 per ct | Dull or greyish green, sparse or muddy spots |
| Good cabochons | $3–$8 per ct | Even green, clear bright red flecks, clean polish |
| Fine, vivid material | $8–$20 per ct | Deep even green with crisp, well-placed “blood” spots |
| Antique carved seals & intaglios | Priced per piece | Value driven by carving quality, age and provenance |
These are Fair Carat’s synthesis of observed dealer listings, not survey data. Bloodstone is inexpensive enough that the quality of the green, the red spots and the polish — not carat weight — decide most of the price.
Watch-outs
- Dull, greyish material. Much bloodstone is pale or muddy with weak spots. It should be cheap; do not pay a premium for lifeless colour.
- Green jasper sold as bloodstone. Plain green jasper with little or no red is not true bloodstone — the red flecks are the whole point.
- Dyeing and enhancement. Some chalcedony is dyed to deepen colour. Natural bloodstone colour is uneven and organic-looking; ask whether a suspiciously vivid stone has been treated.
- Glass and plastic imitations. Moulded imitations lack the stone’s cool feel, natural mottling and hardness. A genuine piece is a hard Mohs 6.5–7 chalcedony.
- Over-restored antiques. With carved seals and signets, re-polishing or recutting can erase detail and value; originality matters for collectible pieces.

Chase even green and crisp red spots — and enjoy the history.
The best-value bloodstone is a deep, even green cabochon with bright, well-placed red flecks and a clean polish. As a tough Mohs 6.5–7 chalcedony, it wears well in rings, signets and beads.

Is bloodstone a valuable gem?
It is affordable rather than valuable in the fine-gem sense. Most cabochons and beads sell for roughly $1–$8 per carat, with fine, deeply coloured stones and antique carved seals worth more per piece. Its appeal is durability, history and striking colour contrast at a low price, not rarity.
Why is it called bloodstone?
Because the red spots of iron oxide scattered through the green stone look like droplets of blood. Its other name, heliotrope, is older still, and in medieval Europe the red-on-green appearance gave the stone strong religious symbolism.
What makes one bloodstone worth more than another?
A deep, even green base and bright, crisp, well-distributed red spots, plus a clean high polish and no dull grey or cracked areas. Pale, blotchy stones with weak markings are common and cheap; vivid, evenly coloured pieces command the premium.
Is bloodstone a birthstone?
Yes. It is a traditional birthstone for March, often listed alongside aquamarine. It has long been used for signet rings and engraved seals because it is opaque, hard-wearing and takes fine detail well.
Can I wear bloodstone every day?
Yes. At about Mohs 6.5–7 with no cleavage, it handles daily wear in rings and bracelets well. Avoid hard knocks and harsh chemicals, and clean it gently with mild soap and water.
How can I tell real bloodstone from an imitation?
Genuine bloodstone is a hard, cool-feeling chalcedony with natural, uneven green colour and organic-looking red flecks. Glass or plastic imitations feel warmer and lighter and often show moulding bubbles or too-perfect spots. For anything valuable, ask for confirmation or a lab report.
