Galaxy Granite is mined in various places in India such as Chimakurthi. Though it is marketed under the term 'granite' because it is hard and dark it is actually Gabbro. Light coloured and soft rocks are almost always marketed under the term Marble. The Galaxy Granite is unusual because it contains small crystals of bronzite which give it a bright sparkly effect and as such is occasionally marketed as Star Granite. Massive shout out to Wendy Kirt and David Cook who published Graveyard Geology. It isn't amazing in a photograph but would like great as a counter or some other decorative stone.
