Labradorite sphere

Labradorite Sphere — Blue, Gold & Rainbow Flash Feldspar

This labradorite sphere displays intense multicolour labradorescence with electric blue, aqua, gold and subtle rainbow flashes appearing across multiple crystal planes.

The darker feldspar body contrasts beautifully against the illuminated flash zones, giving the sphere exceptional depth and movement under light. Several areas also show internal reflective fracture rainbows and strong structural layering typical of high-grade labradorite.

Overview

Labradorite is a feldspar mineral famous for its optical phenomenon known as labradorescence — the bright flashes of colour produced when light refracts and interferes within microscopic layered structures inside the crystal.

This sphere shows strong directional flash with vivid blue and golden tones visible from multiple viewing angles. Internal fractures and crystal boundaries create additional reflective effects and natural rainbow scattering.

Geological & Scientific Notes

Labradorite forms in igneous rocks during the slow cooling of magma.

The vibrant flashes seen in this sphere are caused by microscopic lamellar structures formed during crystal growth. When light enters the stone, it reflects between these internal layers, producing interference colours that shift depending on viewing angle.

This sphere displays several desirable collector features:

• Strong blue and gold labradorescence

• Multiple illuminated flash zones

• Structural crystal layering

• Internal fracture rainbows

• Dark contrasting feldspar matrix

• Directional reflective depth

The darker black inclusions and shadowed zones are likely areas richer in mafic minerals or denser feldspar layering, helping intensify the visible flash.

The rainbow-like bands visible in some illuminated sections are caused by light diffraction along internal fractures and cleavage planes.

Why This Piece Stands Out

• Intense blue and gold flash

• Multiple active flash windows

• Excellent polish enhancing reflectivity

• Strong contrast between dark body and bright colour

• Natural rainbow fracture effects

• High visual depth and movement

• Collector-grade optical display

Care & Handling

Labradorite is durable but contains natural cleavage planes that can fracture under heavy impact.

• Clean with soft cloth and lukewarm water

• Avoid ultrasonic cleaners

• Avoid dropping or hard knocks

• Store separately from harder minerals like quartz
