Lemurian Seed Quartz Identification Guide
Identify Lemurian seed quartz by its distinctive horizontal striations and clear-quartz properties, versus ordinary quartz points.

What Lemurian Seed Quartz Looks Like
Lemurian seed quartz is a marketing/trade name for clear quartz crystals distinguished by strongly developed horizontal striations (ladder-like grooves) running across the prism faces, alternating with smoother faces. Bodies are usually clear to milky, sometimes with a smoky, pink, or tangerine (iron-stained) tint. They are transparent to translucent with a bright vitreous luster and well-formed six-sided prisms ending in pyramidal terminations. Mineralogically it is ordinary quartz (SiO2); the 'Lemurian' designation refers to the striation pattern and origin, not a distinct species.
Step-by-Step Field ID Checklist
- Look for the ladder striations. Pronounced horizontal grooves on some prism faces (felt with a fingertip) are the signature, often described as 'barcode' lines.
- Confirm quartz form. Six-sided prism with pyramidal termination.
- Check clarity and tint. Clear to milky, sometimes with pink/orange iron staining typical of Brazilian material.
- Run a hardness test to confirm quartz.
- Inspect terminations for natural growth, not cut/polished facets.
Key Diagnostic Tests
- Hardness: Mohs 7; scratches glass and steel.
- Streak: White.
- Fracture: Conchoidal; no cleavage.
- Density: ~2.65 g/cm3.
- Acid: No reaction to HCl.
- Optical: Uniaxial quartz; may show natural inclusions or phantoms.
Common Look-Alikes and How to Tell Them Apart
- Ordinary clear quartz points: Chemically identical; the only difference is the prominence of horizontal striations and trade origin. If striations are weak or absent, it is just standard quartz.
- Glass/synthetic quartz points: Manufactured pieces may show mold seams, rows of round bubbles, or perfect symmetry; natural Lemurian quartz has uneven natural growth and striations.
- Topaz: Harder (Mohs 8) with perfect basal cleavage; quartz has none.
- Danburite/beryl: Different crystal forms and densities; lack the quartz striation pattern.
- Calcite points: Much softer (Mohs 3) and fizz in acid.
Where Lemurian Seed Quartz Is Typically Found
The original and most famous Lemurian quartz comes from Brazil (notably the Serra do Cabral area, Minas Gerais), where it was found in sand. Similar striated quartz is now also sourced from Colombia, Russia, Zambia, and elsewhere. Geologically it is hydrothermal/pegmatitic quartz; the 'seed' striation pattern is a natural growth feature.
Frequently asked questions
How can you tell real Lemurian seed quartz?
Genuine Lemurian quartz is clear quartz (hardness 7, density 2.65, conchoidal fracture) with distinctive horizontal ladder-like striations across some prism faces and natural six-sided crystal form. The striation pattern is the defining trait, not a separate mineral identity.
Is Lemurian quartz different from regular clear quartz?
Mineralogically no, it is ordinary quartz. Lemurian is a trade name for clear quartz crystals that display strong horizontal barcode-like striations and typically come from specific Brazilian deposits.
What are the lines on Lemurian quartz?
They are natural horizontal growth striations on the prism faces, formed during crystal growth. You can feel them as ladder-like ridges, and they are the feature collectors use to recognize Lemurian quartz.
Where does Lemurian seed quartz come from?
The classic source is the Serra do Cabral region of Minas Gerais, Brazil, where the crystals were found in sand. Similar striated quartz now also comes from Colombia, Russia, Zambia, and other localities.
