Quick answer

The most useful distinction

Start with streak on expendable material. A pale brown or yellow-brown streak with hard striated prisms favors rutile; a distinct red-brown streak favors hematite.

Field sequence

A practical identification sequence

  1. 1

    Inspect crystal habit and existing fresh surfaces.

  2. 2

    Make a small streak on an inconspicuous expendable area.

  3. 3

    Compare pale brown powder with distinctly red-brown powder.

  4. 4

    Use microscopy or diffraction when the specimen is fine-grained, mixed, or valuable.

Limits and cautions

Where the distinction gets difficult

  • Iron staining can contaminate a rutile streak.
  • Earthy hematite can be much softer than crystalline material.
  • Do not grind ore or damage included quartz and gem specimens.

Use several independent observations. This comparison supports preliminary field identification, not laboratory confirmation, appraisal, proof of origin, or collecting permission.

Common questions

Rutile vs. hematite FAQ

Can rutile be black?

Yes. Iron-rich or opaque rutile can be dark brown to nearly black.

Does rutile leave a red streak?

Typical rutile leaves a pale brown to yellowish-brown streak rather than hematite’s characteristic red-brown powder.

Can the two occur together?

Yes. Both can occur in metamorphic rocks, veins, and heavy-mineral concentrates, and iron-oxide coatings can obscure rutile.

Side-by-side guideQuartz vs. calciteTest an inconspicuous fresh surface. Quartz scratches ordinary glass and breaks with curved or irregular fracture; calcite is scratched by a steel point, cleaves into slanted rhombs, and fizzes with dilute acid.Side-by-side guideQuartz vs. feldsparStudy how the grain ends. Quartz usually has curved or irregular broken surfaces with no repeated flat direction; feldspar commonly shows two recurring cleavage planes that meet near 90 degrees.Side-by-side guideMuscovite vs. biotiteFirst confirm mica by its elastic, peelable sheets. Then compare thin flakes rather than a thick book: pale, nearly colorless sheets favor muscovite; brown, green-brown, or black sheets favor biotite.Side-by-side guideHematite vs. magnetiteUse both a magnet and an unglazed streak plate. Strong attraction with a black streak favors magnetite; a red-brown streak with weak or absent attraction favors hematite.Side-by-side guideGypsum vs. calciteBegin with hardness. A fingernail scratch favors gypsum; material that resists a fingernail but scratches under a copper coin favors calcite. A clean calcite surface then fizzes readily with dilute acid.Side-by-side guideFluorite vs. quartzDo not use color. Quartz readily scratches glass and breaks without cleavage; fluorite is scratched by steel and commonly breaks into triangular-faced octahedral fragments along four cleavage directions.Side-by-side guidePyrite vs. goldTest behavior, not sparkle. Pyrite scratches glass and crushes or breaks; a loose gold grain is scratched by copper, flattens rather than shattering, and feels unusually heavy for its size.Side-by-side guidePyrite vs. chalcopyriteUse hardness and form together. Pyrite commonly scratches glass and preserves sharp striated cubes; chalcopyrite is readily scratched by steel and typically occurs as softer irregular grains or masses.Side-by-side guideQuartz vs. diamondDo not use a destructive scratch test on an unknown valuable crystal. Crystal form and geologic context can rule out many quartz specimens, but suspected diamond should be screened with appropriate gemological instruments.Side-by-side guideGypsum vs. talcBoth yield to a fingernail, so compare degree and feel. Talc scratches with almost no effort and often feels greasy; gypsum offers slightly more resistance and shows characteristic bladed, fibrous, or clear cleavage forms.Side-by-side guideCalcite vs. dolomiteUse a controlled acid test on expendable material. A clean calcite surface effervesces immediately; dolomite usually needs powdering to produce an obvious cold-acid reaction.Side-by-side guideGold vs. copperFind a natural fresh surface without damaging the specimen. Gold remains yellow and feels exceptionally heavy; copper is distinctly redder, less dense, and commonly associated with green or blue alteration minerals.Side-by-side guideSilver vs. galenaUse breakage behavior and cleavage, not shine. Cubic steps and brittle fragments favor galena; wirelike or irregular metal that bends or cuts without crumbling favors native silver.Side-by-side guideGalena vs. sphaleriteCompare cleavage geometry and streak. Cubic right-angle fragments with a gray-black streak favor galena; many flashing cleavage faces with a pale yellow to brown streak favor sphalerite.Side-by-side guideQuartz vs. corundumUse crystal form and provenance first. Corundum scratches quartz, but do not perform destructive scratch tests on attractive or potentially valuable crystals; uncertain gem material belongs with a qualified gemologist.Side-by-side guidePyrite vs. galenaA cube alone is not enough. Pyrite scratches glass and may show striated crystal faces; galena is scratched easily, feels unusually heavy, and breaks along smooth right-angle cleavage planes.Side-by-side guideGraphite vs. molybdeniteCompare heft before color. A compact molybdenite piece feels much heavier than equal-volume graphite, while graphite usually makes a blacker mark and is common in carbon-rich metamorphic rock.Side-by-side guideMalachite vs. azuriteUse streak on expendable material and expect mixtures. Green powder favors malachite, blue powder favors azurite, and blue-green zoning may record intergrowth or azurite altering to malachite.Side-by-side guideMalachite vs. native copperLook beneath coatings without damaging the specimen. Green, brittle, green-streaking material favors malachite; copper-red metal that deforms rather than crumbles favors native copper.Side-by-side guideSulfur vs. pyriteCheck luster and hardness, not odor. Soft resinous yellow material favors sulfur; flashing metallic grains that scratch glass and leave a dark streak favor pyrite.Side-by-side guideGraphite vs. galenaHeft and cleavage separate them. Lightweight material that marks readily and splits into flakes favors graphite; a very heavy blocky specimen with right-angle cleavage favors galena.Side-by-side guideApatite vs. fluoriteTest hardness and breakage. Apatite at Mohs 5 can scratch fluorite; fluorite at Mohs 4 develops repeated triangular octahedral cleavage faces.Side-by-side guideTopaz vs. quartzCleavage and crystal form are safer than scratch tests on good specimens. A flat repeated basal cleavage favors topaz; curved fracture and six-sided pyramidal crystals favor quartz.Side-by-side guideBeryl vs. quartzStudy the prism and termination. Flat-ended, longitudinally striated hexagonal prisms favor beryl; pyramidal points and conchoidal fracture favor quartz.Side-by-side guideTourmaline vs. garnetUse crystal shape rather than color. Long grooved prisms favor tourmaline; compact many-faced equant crystals favor garnet.Side-by-side guideKaolinite vs. talcUse feel and relative hardness cautiously. A greasy mass scratched effortlessly by a fingernail favors talc; dull earthy clay near Mohs 2 to 2.5 may be kaolinite but commonly needs X-ray diffraction for confirmation.Side-by-side guideHornblende vs. tourmalineCheck breakage and cross section. Repeated cleavage near 60 and 120 degrees favors hornblende; deep lengthwise grooves and a rounded-triangular section favor tourmaline.Side-by-side guideAugite vs. hornblendeMeasure the intersection of repeated cleavage surfaces. Near-right angles favor augite; distinctly oblique amphibole angles favor hornblende.Side-by-side guideSerpentine vs. malachiteUse streak and texture without generating dust. Green powder and concentric or botryoidal structure favor malachite; white streak and waxy, scaly, or fibrous material favor serpentine.Side-by-side guideChlorite vs. biotiteTest an already loose flake. Green, very soft material that bends without springing back favors chlorite; brown-black elastic sheets favor biotite.Side-by-side guideEpidote vs. olivineLook for cleavage and setting. One repeated flat cleavage in pistachio-green prismatic material favors epidote; rounded or sugary olive-green grains with poor cleavage favor olivine.Side-by-side guideBarite vs. calciteCompare heft, then acid response on expendable material. Exceptional density without fizz favors barite; ordinary heft with immediate effervescence favors calcite.Side-by-side guideCelestite vs. bariteDo not use blue color alone. Measure density carefully: barite is commonly near 4.5, celestite near 4.0, with natural solid solution and attached matrix capable of blurring the result.Side-by-side guideKyanite vs. corundumUse habit and existing breakage. Flat cleavable blades favor kyanite; compact crystals with extreme uniform hardness and no cleavage favor corundum.Side-by-side guideStaurolite vs. garnetUse crystal geometry. Stout prisms or natural cross twins favor staurolite; compact many-faced or rounded crystals favor garnet.Side-by-side guideGoethite vs. hematiteIgnore surface color and use streak. Ocher-yellow to yellow-brown powder favors goethite; distinctly red-brown powder favors hematite.Side-by-side guideIlmenite vs. magnetiteCompare magnetic strength with a known magnet, then streak. Strong attraction and black powder favor magnetite; weak response with black to brownish-red powder may favor ilmenite.Side-by-side guideZircon vs. diamondDo not scratch a possible gem. Examine crystal form and facet doubling, then use refractive index, density, thermal response, and professional testing rather than destructive checks.Side-by-side guideCassiterite vs. sphaleriteUse existing breakage and hardness on expendable material. Very heavy, hard material with poor cleavage favors cassiterite; softer resinous material with repeated cleavage favors sphalerite.Side-by-side guideMonazite vs. zirconDo not use color or a radiation reading alone. Intact tetragonal prisms and hardness near 7.5 favor zircon; softer resinous grains with monazite chemistry require optical or analytical confirmation.
