Short answer: "Lemurian" is a dealer's trade name, not a mineral or a recognized variety. The crystals are ordinary quartz (SiO2, Mohs 7, specific gravity 2.65), usually long clear or frosted points from Minas Gerais, Brazil, chosen for pronounced horizontal grooves across alternating prism faces. Those grooves are normal quartz growth striations. Judge a Lemurian point as you would any natural quartz point: by clarity, termination, striations, damage and an honest locality.
Is Lemurian quartz a real variety of quartz?
Not in the mineralogical sense. Quartz references list dozens of variety names, from rock crystal and smoky quartz to aventurine and phantom quartz, and none of them is "Lemurian". Minerals.net, for example, catalogs varieties down to obscure regional names without one entry for it. The name belongs to the crystal trade, where it entered use in the late twentieth century for a style of Brazilian point and was attached to Lemuria, a sunken continent of nineteenth-century speculation and later occult storytelling. No geological evidence links the crystals to any lost land.
That does not make the crystals fake. A piece sold as Lemurian is real, natural quartz. The label simply describes a look, and the look is worth understanding, because the same features that define a good Lemurian point define a good natural point of any name. The run of trade names like this one is covered in the guide to crystal trade names.
What the mineral itself is
| Property | Value |
|---|---|
| Formula | SiO2 |
| Crystal system | Trigonal (often described as hexagonal) |
| Mohs hardness | 7 |
| Specific gravity | 2.65 |
| Refractive index | about 1.544 to 1.553 |
| Cleavage | None; conchoidal fracture |
Webmineral gives the specific gravity of quartz as 2.65 gm/cc and the crystal system as trigonal. The International Gem Society records the specific gravity as 2.651 (very constant) and the refractive indices as 1.544 and 1.553. Those numbers are identical for a $3 Brazilian point and a $300 one sold under a romantic name. Geology.com lists conchoidal fracture, glassy luster and hardness as the diagnostic properties, which is why chips on a quartz point show curved, shell-like scars.
What are the horizontal lines on a Lemurian crystal?
They are growth striations: fine parallel grooves that run across the prism faces at right angles to the length of the crystal. Minerals.net notes that quartz crystals are usually striated horizontally, and lists striations on crystal faces among the striking features of the species. In other words, striations are the rule in quartz, not a special signature.
What makes a crystal "Lemurian" in the trade is how strong and regular the striations are. On the classic Brazilian points the grooves are deep enough to feel with a fingernail and are spaced like rungs of a ladder, often on alternating faces of the six-sided prism. They form because the crystal does not grow evenly. As a quartz crystal builds outward, its faces advance in steps; the prism faces and the small rhombohedral faces compete, and the record of that competition is a series of tiny alternating ledges. Strong striation simply means that the oscillation was pronounced during growth.
How do striations help identify natural quartz?
Striations are one of the most useful clues that a point is a natural crystal and not a polished shape. A cut and polished "point" has flat, mirror-smooth sides; a natural crystal has striated prism faces and slightly uneven faces at the tip. Run a fingernail across the length of the prism: on a natural point it catches on the ridges. The guide to natural vs cut points explains this check in more detail.
Where does Lemurian quartz come from?
The name grew up around quartz from Minas Gerais in Brazil, and Brazil still supplies most of it. Minas Gerais is one of the world's great quartz provinces. According to Minerals.net, some of the largest and most impressive quartz crystals, weighing many tons and yet still perfectly formed, come from several pegmatite districts in the state of Minas Gerais. The International Gem Society lists Minas Gerais among the principal sources of rock crystal, alongside Hot Springs, Arkansas, Herkimer in New York, the Swiss Alps and Madagascar.
The Lemurian label is now used loosely. Points from other Brazilian quartz districts, and sometimes from other countries, are sold under it whenever they show strong striations. A careful seller will name the state or district; a vague "Lemurian from Lemuria" is marketing, and a buyer should expect nothing more specific than "Brazil".
Why are some Lemurian points pink, orange or frosted?
Color and surface texture come from coatings and inclusions, not from a different kind of quartz. Minerals.net explains that in some localities hematite forms a thin red or brown layer internally in the quartz crystal, giving it a natural bright red to brown coloring. Iron oxide on or just under the surface produces the pink and orange points sold as "pink" or "tangerine" Lemurians. A frosted or matte skin is often natural etching, but tumbled or acid-treated surfaces exist too, so a perfectly even frost over every face is worth a question.
What growth features show up in these points?
Lemurian points are long prismatic quartz, and they share the full range of quartz growth habits. Minerals.net describes several that collectors look for:
- Phantoms: a phantom growth, where one crystal forms over another, leaving a ghosted form inside. A thin hematite or clay film can outline an earlier tip inside a Lemurian point. See phantom quartz.
- Scepters: a scepter growth, where the top of a crystal bulges out from the rest of the crystal.
- Twins: quartz crystals frequently twin, and the Japanese twin joins two crystals at about 90 degrees.
- Double terminations: points that grew free in clay or a pocket can have a tip at both ends.
None of these is unique to Lemurian material, but a striated point that also shows a clean phantom or a sharp twin is a better specimen than a plain one.
How do you judge a Lemurian point?
Use the same scale you would use for any natural quartz point:
- Termination. A complete, sharp tip with all faces intact is the first thing to check. Small chips ("dings") on the tip edges are common and lower the price; a reground or polished tip is not a natural termination.
- Striations. Look for deep, regular, ladder-like grooves along the prism. Faint or patchy lines are ordinary quartz.
- Clarity. Water-clear points cost more than cloudy or milky ones. Internal fractures that flash rainbows are natural but count as flaws.
- Base. Most points broke off a cluster, so the base is a rough break. That is normal; a ground flat base for standing is a modification and should be disclosed.
- Surface. Natural iron staining is fine; heavy, uniform frosting or color that rubs off may indicate treatment.
- Locality. "Minas Gerais, Brazil" or a named district is better than "Lemuria".
In crystal traditions Lemurian points are associated with ancient wisdom and connection, a story attached to the trade name rather than to anything measurable in the crystal.
Shopping the Lemurian and Brazilian quartz we stock
A Lemurian point is a quartz point with a particular surface, so it pays to compare it with other natural points of known origin. Look at the listing photos for the prism faces in raking light, where striations show best, and for chips on the termination.
- Lemurian quartz from Brazil: the trade-name point itself, an affordable way to see the horizontal striations up close and compare them with plain quartz.
- Raw clear quartz points from Brazil: small natural Brazilian points with high clarity; check their prism faces for striations, and you will see that the feature is not exclusive to Lemurian stock.
- Large quartz cluster with an XL point, Minas Gerais: a 10 by 16 by 25 inch museum-scale cluster from the same Brazilian state, showing how the long prismatic points grow together.
- Natural quartz point with stand, Madagascar, about 0.49 lb: a non-Brazilian comparison point at display size, useful for judging termination and clarity side by side.

Frequently asked questions
How can you tell if a crystal is really Lemurian?
There is no test, because Lemurian is a trade name, not a mineral. What can be checked is whether the piece is natural quartz with strong horizontal striations on its prism faces, an intact natural termination, and a stated locality, usually Minas Gerais, Brazil.
Are Lemurian crystals rare?
No. Strongly striated quartz points are produced in quantity in Brazil and sold worldwide. Fine examples with water-clear bodies, deep regular striations, undamaged tips and a phantom or twin are less common and priced accordingly.
Do all quartz points have striations?
Most natural quartz crystals show horizontal striations on their prism faces, though often faint. Lemurian points are selected for unusually deep, regular grooves. Cut and polished points have smooth sides and no striations at all.
Why are some Lemurian crystals pink?
Pink to orange Lemurians owe their color to a thin coating or film of iron oxide such as hematite on or just beneath the surface. The quartz underneath is colorless. Rubbing or acid cleaning can remove some of the color, so clean these gently.
How should a Lemurian point be cleaned?
Quartz is hard and chemically tough, so warm water, mild soap and a soft brush are safe for clear points. Avoid harsh acids on iron-coated pink or orange points, and protect the termination from knocks, since quartz chips along conchoidal fractures.
