Description: Vizag Blue granite is a fine-grained, blue-grey gneiss of the Precambrian period with small red garnets. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as a gneiss. The veining and colour varies considerably and a small sample of Vizag Blue granite may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. During the polishing process a clear epoxy resin filler may be used to fill any micro fissures or tiny pitting however this does not affect the integrity of the stone, it merely provides an even smoother surface finish. Vizag Blue granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.

Surface Finish: Vizag Blue granite looks best with a gloss polished surface but is also available as honed, leather/satin, river-washed/antique, thermal/flamed, brushed and sandblast finish. We never use colour enhancers.
Sealing: Test with a small sample. It is possible that a sealant can be used on Vizag Blue granite however excessive attempts at sealing it could actually create a residue film build-up.
Block Sizes: There are many granite quarries yielding several, selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized and monument blocks. Extraction commenced in the late 1980s. For commercial projects it is important to ensure that blocks are selected from the same quarry face.
Rough blocks are usually exported by Break Bulk however intermodal containerisation is available at extra cost. Finished products are packed into sea-worthy wooden crates and loaded into containers.
Quarry Location: Vizag Blue granite is quarried at Tekkali, Vizag, Srikakulam, Vishakhapatnam, Andhra Pradesh, India. There are more than 40 quarries with varying shades from light to dark. The veining and colour varies considerably.
Synonyms: Andhra Blue, Azul Magnetic, Azul Vizag, Blue Vizag, Blue Vizag India, Brindel Blue, Ganga Blue, Gangablue, Vaizag Blue, Visag Blue, Vizac Blue, Vizag, Vizag Bleu, Vizag Blu, Vizak Blue, Vizaq Blue, Vizga Blue
Gneiss: A high grade metamorphic rock. Gneiss is medium to coarse-grained and may contain abundant quartz and feldspar, which some petrographers regard as essential components. The banding is usually due to the presence of differing proportions of minerals in the various bands; dark and light bands may alternate because of the separation of mafic (dark) and felsic (light) minerals. Banding can also be caused by differing grain sizes of the same minerals. The mineralogy of a particular gneiss is a result of the complex interaction of original rock composition, pressure and temperature of metamorphism, and the addition or loss of components.
