40mm Labradorite Sphere Polished Feldspar Crystal Orb Specimen From Alice Purnell Collection with Certificate of Authenticity

Polished Labradorite Sphere – 40mm Natural Feldspar Crystal

This stunning 40mm Labradorite Sphere is a genuine natural mineral specimen, carefully selected for its attractive colour play and smooth polished finish. Offered from the Alice Purnell Collection, this piece includes a Certificate of Authenticity lifetime guarantee generic card. The photographs show the exact sphere you will receive, and full sizing details can be seen clearly in the listing images.

Labradorite spheres are highly valued for their decorative appeal, collectible mineral significance, and the unique optical effect known as labradorescence, which creates flashes of blue, green, gold, or grey depending on the light angle.

Mineral Information – Labradorite Feldspar

Labradorite is a calcium-sodium feldspar mineral belonging to the plagioclase feldspar series. Its chemical composition falls between albite and anorthite, and it crystallises in the triclinic crystal system.

Labradorite is best known for its shimmering iridescent effect, caused by light interference within microscopic lamellar structures inside the stone. This phenomenon, called labradorescence, gives the mineral its distinctive glowing flashes that make each piece unique.

The base colour of labradorite is typically grey to dark charcoal, often with reflective internal colour zones that appear when the surface catches the light.

With a Mohs hardness of around 6 to 6.5, labradorite is durable enough for display and handling, while still requiring care to avoid scratches from harder minerals.

Geological Formation and Origin

Labradorite forms in igneous rocks such as basalt, gabbro, and anorthosite, where slow cooling magma allows feldspar crystals to develop. It is commonly found in large crystalline masses within intrusive rock bodies.

Notable labradorite deposits occur in regions such as Madagascar, Canada, Finland, and Russia, with Madagascar being especially well known for producing vivid labradorescent material often carved into spheres and decorative forms.

The sphere shape highlights labradorite’s internal optical features beautifully, allowing flashes of colour to appear across the curved surface from multiple viewing angles.

Sphere Craftsmanship and Display Appeal

This 40mm sphere has been carefully polished to a smooth, reflective finish, enhancing the natural labradorescence and colour depth of the stone. Crystal spheres are popular among collectors because they provide a balanced, elegant way to display mineral beauty.

This specimen is ideal for:

• Mineral and crystal collectors

• Feldspar and labradorite enthusiasts

• Decorative display in home or office settings

• Photography and styling pieces

• Unique gifts for geology and natural history lovers

Labradorite has also been traditionally associated with spiritual symbolism in various cultures, though it is most widely appreciated today for its remarkable optical properties and geological origin.
