Description: Colonial Gold granite is a medium to coarse-grained, grey-yellow granulite of the Precambrian period with some deep 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 granulite. The veining and colour varies considerably and a small sample of Colonial Gold 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. Colonial Gold 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: Colonial Gold 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.
Sealing: Test with a small sample. It is possible that a sealant can be used on Colonial Gold granite however excessive attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is a quarry yielding selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized blocks. 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: Colonial Gold Granite is quarried near Melur, Madurai, Tamil Nadu, India. There are several quarries of Colonial Gold and the veining and colour varies considerably.
Granulite: A class of high grade metamorphic rocks of the granulite-facies that have experienced high-temperature and moderate pressure metamorphism. They are medium to coarse-grained and mainly composed of feldspars sometimes associated with quartz and anhydrous ferromagnesian minerals, with granoblastic texture and gneissose to massive structure. The granulites are very closely allied to the gneisses, as they consist of nearly the same minerals, but they are finer-grained, have usually less perfect foliation, are more frequently garnetiferous, and have some special features of microscopic structure.
