Flash Blue Granite.
Flash Blue Granite is a deep blue-grey stone from Andhra Pradesh distinguished by a striking flash iridescence across its dark surface — a refined, less dramatic alternative to full labradorescent Blue Pearl that suits contemporary luxury interiors.
About Blue
Flash Blue Granite is quarried in Andhra Pradesh's granite belt, within the Eastern Ghats geological zone, where mafic intrusives produce the dark blue-grey matrix and characteristic iridescent flash of the stone. Block selection prioritises consistent shimmer character and colour depth before processing to gangsaw slabs and calibrated tiles for export. FOB Mundra / Nhava Sheva. Origin and specifications verified by Gemarix.
Geological Profile
Flash Blue is a medium-to-coarse grained mafic granitoid dominated by plagioclase feldspar with secondary hornblende, pyroxene, and ilmenite. The blue-grey matrix results from the combination of dark hornblende-pyroxene and lighter plagioclase phases, while the flash iridescence originates from oriented feldspar cleavage planes that reflect light at specific angles. The effect is less pervasive than full labradorescence but appears as vivid flashes of blue-grey light across the stone surface when the viewing angle changes. The low porosity gives the stone good stain resistance.
Color & Character
Flash Blue Granite presents a deep blue-grey to charcoal matrix with a distributed iridescent flash that appears as sudden, planar blue-grey light reflections across the stone surface when the viewing angle shifts. Unlike fully labradorescent stones where the shimmer is omnipresent, the flash in Flash Blue appears and disappears with movement — creating a more subtle, animated quality. The dark ground gives depth and sophistication, while the iridescent flashes add visual interest without overwhelming the space. The stone has a composed, contemporary character.
Best Applications
Kitchen Countertops
Flash Blue's deep blue-grey tone and subtle iridescence make it a sophisticated kitchen worktop material for contemporary interiors where a dark, restrained stone is preferred over a high-drama labradorescent alternative.
Feature Walls
Polished Flash Blue slab feature walls in contemporary residential and hospitality interiors create a dark, moody backdrop with animated iridescent detail.
Bathroom Surfaces
Vanity tops and shower walls in Flash Blue create dark, refined bathroom environments with the added depth of the stone's iridescent flash.
Flooring
Large-format polished Flash Blue tiles create dark, sophisticated floor surfaces in luxury residential and commercial spaces.
Reception Desks
The stone's combination of dark depth and controlled iridescence makes it a refined specification for reception counters in contemporary commercial buildings.
Exterior Facades
The stone's density and low porosity make it suitable for sheltered exterior cladding and entrance feature applications.

Care & Maintenance
Flash Blue Granite should be sealed with an impregnating sealer at installation and re-sealed every 18 months in kitchen and bathroom applications. The dark surface can show water marks on polished finishes; dry promptly after cleaning. Use pH-neutral stone cleaner and avoid abrasive products that could micro-scratch the polished feldspar surface and reduce the iridescent flash. The stone's shimmer character is stable and does not diminish with normal use.
