help with Bianco Romano/White Springs Granite (http://tanbrown.org)

Hi guys! I am hoping to get some general info about my Granite (http://tanbrown.org) . The Stone (http://g603.net) yards and (http://maplered.com) fabricator gave only generic Granite (http://tanbrown.org) info. I have Bianco Romano/White Springs Granite (http://tanbrown.org) that appears to be resined (clear amber filling in obvious cracks and (http://maplered.com) fissures?) The areas that are heavily resined appear dull instead of shiny, is that normal and (http://maplered.com) expected? Also, do I need to seal this Granite (http://tanbrown.org) ? I poured a little water on it and (http://maplered.com) it beaded up and (http://maplered.com) did not appear to soak into the Stone (http://g603.net) ...but the Colors (http://www.g640.net) of the Stone (http://g603.net) would obscure that sort of mark, so it is hard to tell. Is there anything else I could do to "test" the Stone (http://g603.net) ? The fabricator hasn't given me scraps, so I can't test for staining etc.
Thanks for your advice!
