If you are a jewelry maker, wire jewelry artisan, gemstone collector, B2B trader or reseller sourcing high quality bloodstone for sale is crucial for crafting pieces that are durable and visually attractive. Bloodstone, also known as heliotrope, is one of the most sought after gemstones due to its incredible contrast of deep green and vivid red colors.
Unfortunately the surge in demand of bloodstone has led to dyed jasper, resin imitations and many other alternative synthetics that are sold in the market by misleading genuine buyers. This guide will help you evaluate real vs fake bloodstone and make confident purchasing decisions protecting your investment from fakes and imitations.
How to Tell if Bloodstone Is Real?
The most simplest way to identify if a bloodstone is real is to check for red inclusions that are naturally distributed on an opaque forest green base. This forest green base and red inclusions are found on natural bloodstones as a variety of chalcedony (cryptocrystalline quartz) and the red spots are formed due to iron oxide (hematite).
To identify a fake version of bloodstone look for overly bright paint colors and signs of chemical or dye treatment on the stone. A natural bloodstone is irregular unlike imitation stones that display perfect dimensions and cuts.
How to Identify Real Bloodstone: 5 Visual Checks
For B2B resellers and jewelry makers looking to source wholesale parcels or individual stones these five visual checks will help you distinguish real bloodstone from the fake ones.
1. Spot Distribution
Examination of the red spot distribution across the stone is one of the easiest and reliable ways of identification of genuine bloodstone. Uneven distribution of red inclusions across the matrix of the stone refers to the stone being genuine. Perfectly even or overly clustered spots on the stone is a sign that the stone is an imitation or a fake.
2. Color Depth
Genuine and authentic bloodstone features a dark green base color with minor yellow or brown accents with subtle variations across the body of the stone. Overly bright green color that looks artificial often signals dye treatment or cheap fakes.
3. Polish and Luster
Inspect the polish on the stone carefully. A genuine and natural bloodstone shows waxy to glassy lustre when polished on the other hand imitation and cheap fakes display plastic like shine when seen under UV light or natural sunlight.
4. Hardness Check
On Mohs hardness scale natural bloodstone ranks about 6.5 -- 7 which makes it quite dense and hard gemstone. Plastic and resin substitutes scratches easily when compared to real bloodstone that is tough and cannot be easily scratched by coin or fingernails.

5. Weight (Density):
Natural bloodstones come with a specific gravity of about 2.6 which makes it dense and heavy. Unlike imitations and cheap fakes that feels very light weight when picked up or held in hands signaling hollowing of fakes.
How to Test Bloodstone at Home?
Confirm your bloodstone authentication beyond visuals with these three simple and easy tests that can be performed from the convenience of your home.
The Scratch Test:
With the hardness of 6.5 to 7 on a Mohs hardness scale, a genuine bloodstone is not easy to scratch. Try scratching the stone against glass or coins. If it leaves a mark or a groove it is a cheap fake or imitation stone.
Note: Please perform the test carefully as it may lead to damage of polish and cut of the bloodstone
The Streak Test:
A natural bloodstone leaves little to no streak when rubbed against unglazed white porcelain tile. When rubbed if you see a blood red streak on the tile the stone is genuine bloodstone unlike plastics and resins that leave a black or gray mark on the tile.
The Acetone Test for Dye:
A dyed bloodstone can be identified by performing the acetone test. Dampen a cotton swab with pure acetone or a heavy duty nail polish remover and gently rob on the inconspicuous area (red or green area of the stone). If you see a transfer of color on the swab it is a clear indication that the stone is dyed or treated.
Note: Carefully perform the test only on the stones that you own.
Dyed Jasper vs Real Bloodstone: Key Differences
The rise in the demand of natural bloodstones in B2B markets and jewelry manufactures has led to a large number of stones marketed as natural bloodstone but are dyed jasper, a frequent imitation of real bloodstone. These sophisticated fakes are made by sourcing pale green common jasper and dye it to pass it on in the trading markets as premium mineral.
Refer to the table below to understand the primary difference between dyed jasper and real bloodstone.

-
Red spots that don't feel natural and overly bright colors.
-
Uniform green coloration across the matrix that looks too perfect.
-
Patterns that repeat across multiple stones in one batch.
-
Transfer of color when rubbed across cotton or swab.
-
Prices that feel too good to be true compared to current trading price trends.
-
Seller not able to provide or avoid disclosing origin details and treatment details if any.
-
Very light weight and plastic-like feel and look of the stone when picked up or held in hands.
Request for detailed photographs and complete disclosures when shopping for natural bloodstones online from the seller. For deeper reading, check the Bloodstone Buying Guide or Bloodstone 101. Always ask for source details and compare multiple pieces.

FAQ: Spotting Fake Bloodstone
Can dye in fake bloodstone fade? Yes. Over time, chemically dyed bloodstone imitations will fade significantly when exposed to direct sunlight, heat, or mild jewelry cleaning solutions, leaving you with a dull, greyish-green rock.
Does real bloodstone have to have red spots? Technically, yes. While the base mineral is green chalcedony (plasma), it is specifically the red iron oxide inclusions that classify the mineral as bloodstone. You can learn more about its geological makeup in our comprehensive Bloodstone 101 guide.
Is lab-created bloodstone a thing? No, there is currently no commercial lab-grown or synthetic bloodstone on the market. "Synthetic" or "lab" versions sold online are almost always masquerading glass, plastic resin, or dyed substitute minerals.
