Mineral Classification & Composition
Labradorite is a feldspar mineral belonging to the plagioclase feldspar group, with a chemical composition typically expressed as (Ca,Na)(Al,Si)₄O₈. It forms within the triclinic crystal system and is widely recognised for its remarkable optical phenomenon known as labradorescence.
Key mineral information:
-
Mineral Species: Labradorite (Plagioclase Feldspar)
-
Mineral Group: Feldspar
-
Crystal System: Triclinic
-
Hardness: 6–6.5 on the Mohs scale
-
Lustre: Vitreous to pearly
-
Transparency: Translucent to opaque
Its internal lamellar structure causes light interference, producing flashes of metallic colour across the surface when viewed from different angles.
Optical Effect – Labradorescence
The most distinctive feature of Labradorite is labradorescence, an optical effect caused by light reflecting within microscopic twin layers inside the crystal. This produces vibrant flashes of colour that can include:
-
Electric blue
-
Green
-
Gold
-
Copper
-
Orange
-
Multicolour iridescence
The base colour of the stone is typically grey to dark grey, with colour flashes appearing as the stone is moved under light. Each specimen displays unique colour patterns, making every piece visually distinctive.
Geological Formation & Madagascar Origin
Labradorite forms in igneous rocks such as basalt, gabbro, and anorthosite. It crystallises from cooling magma, often within large intrusive bodies or volcanic formations. Madagascar is internationally known for producing high-quality Labradorite with strong colour flashes and attractive surface polish.
Madagascan Labradorite is particularly valued for:
-
Intense blue and multicolour flashes
-
Stable, solid material suitable for shaping
-
Attractive natural patterns
Associated minerals in its geological environment may include pyroxene, olivine, and other feldspar varieties.
Form, Finish & Display Appeal
This specimen has been shaped and polished to enhance its natural labradorescence while maintaining its authenticity as a natural feldspar mineral. The polished surface allows light to enter and reflect internally, maximising the visible colour play.
At approximately 40–80mm, this piece is ideal for:
-
Mineral and crystal collections
-
Display cabinets and shelves
-
Decorative interior accents
-
Educational geological samples
-
Unique gifts for collectors
Each stone is natural and untreated beyond standard cutting and polishing to reveal its internal structure.
Collecting & Traditional Associations
Labradorite is highly regarded among mineral collectors for its optical properties and geological significance. Its colour play makes it a standout addition to any collection of feldspars or iridescent minerals.
In spiritual traditions, Labradorite is traditionally associated with transformation and protection; however, this listing presents the stone purely as a natural mineral specimen without any claims beyond its collectible and decorative value.
