Vizag Blue Granite, Azul Vizag Granite
Please note that these are average samples only. Due to Vizag Blue Granite being a natural material, rough block, slabs, tiles, and monuments are all liable to vary in colour and veining, therefore absolute resemblance cannot be guaranteed. Swatch samples must be approved for large projects since there are more than 40 quarries all with their own unique colour and veining variations.

Description: Vizag Blue Granite is a fine-grained, purple-blue-grey, charnockitized gneiss also considered to be a garnetiferous migmatite, of the Precambrian period usually with many small red garnets. This stone internationally may be nominated as a granite. For the US and Chinese market this is correct but in the area of application of the European Standard this stone must be nominated as gneiss.
Charnockite: A hypersthene granite typical of Precambrian assemblages that contain migmatites. Charnockite is composed of orthoclase, oligoclase, quartz, and hypersthene; it also often includes the garnets almandine and pyrope, as well as biotite, magnetite, and other minerals. Two types of charnockites are distinguished: ferrohypersthene charnockite and garnet charnockite.
Gneiss: A common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. Gneissic rocks are usually medium to coarse-foliated and largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, etc.
Migmatite: A rock at the frontier between igneous and metamorphic rocks. They can also be known as diatexite. In many cases the darker part of the rock, consisting of biotite mica and hornblende, has been intruded by veins of lighter rock consisting of quartz and feldspar. A rock composed of a metamorphic (altered) host material that is streaked or veined with granite rock; the name means "mixed rock". Such rocks are usually gneissic (banded) and felsic rather than mafic in composition.
Vizag Blue Granite : Technical Specifications
| Description |
Vizag Blue Granite has a dark grey to blue background with small red garnets plus grey and/or light to dark blue heavy veining extremely common. There are more than 40 different quarries of Vizag Blue granite therefore the colour and veining can vary considerably. For large projects ensure that the blocks are all extracted from the same quarry for matching purposes.
Even First Choice material will have lines and veins. It is quite common to use a resin filler in Vizag Blue Granite to give a more smooth feel to the surface. Vizag Blue granite may absorb liquid therefore a good quality sealer should be tested before using as a work surface. |
| General Usage |
It is mainly used for flooring, cladding, kitchen counters and table tops. Vizag Blue Granite looks good with a gloss polish however it is also available flamed, river-washed and honed. Available in both slabs and tiles. |
