This stone internationally may be nominated as a granite. For the US- and Chinese market this is correct according to ASTM C 119 resp. GB/T 17670. But in the area of application of the European Standard (EN) this stone must be nominated as quartz syenite because the EN 12440 demands a scientific terminology for the denomination of natural stones, determined with a petrografic examination according to EN 12407 and 4.2 of prEN 12670. In case of doubt please ask your supplier.
