Location: Padang Dark granite is quarried near Changle, Fujian province, China. There are many different quarries all producing slightly different shades and graining.
Description: Padang Dark granite is a fine-grained, dark grey Quartz Diorite of the Precambrian period. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a Quartz Diorite.
The veining and colour varies from quarry to quarry and a small sample of Padang Dark 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. Ideal for both interior and exterior use, Padang Dark granite is frost free and polish constant.

Quartz Diorite: Quartz Diorite is 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.
