Description: G654 Granite is a fine-grained, dark grey Quartz Diorite of the Precambrian period. 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 Quartz Diorite. A small sample of G654 granite is usually representative not having a wide variation in colour and veining however 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. G654 Granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
There are principally three selections of G654 granite as shown here, left to right, fine, medium and coarse. This is an extremely economical granite and very popular for covering large paved areas.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: G654 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: It is most unlikely that a sealant can be used on G654 granite due to the very tight grain formation, 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: G654 Granite is quarried near Changle, Fujian province, China. There are many different quarries all producing slightly different shades and graining.

Quartz Diorite: A medium to dark grey, medium to coarse-grained intrusive rock. It consists mainly of plagioclase feldspar, some quartz, and abundant dark minerals (roughly a third). The dark crystals are usually hornblende and biotite, with minor pyroxene.
