My step-son and grand-daughter brought these back from Emerald Island NC. We think that they're quartzite, but that seems an odd find for an Atlantic Coast beach, though.

Interesting... Not sure where they disappeared to. I'll repost them later today. (Not at home right now.) Yes it did!  I can't help with the ID...I just couldn't see the pictures.  |

Greetings from Scotland, Could be Quartz (a pen knife leaves a metallic streak instead of a scratch), however color suggests Calcite
(fizzles with table vinegar).

Looks like quartz to me too. There is a lot of rock that is hauled in from inland quarries that is used to help stop the erosion along the North and South Carolina coast. It's also used to build the jetties. Usually it is mostly granite with some quartz mixed in.

Halò! Could be Quartz (a pen knife leaves a metallic streak instead of a scratch...(fizzles with table vinegar).
Nope. No streak, just a slight scratch. ...color suggests Calcite (fizzles with table vinegar). Nope. No fizzle. The rocks merely got wet.

Could be quartz. It's not quartzite. If the quartz crystals are not super solid, it might appear as through you are scratching the rock, when in fact, you are breaking up the loose crystals.
My guess is its something in the feldspar family. The horizontal fractures shown in your last photos are typical of a lot of feldspar rocks. Quartz does not usually fracture that way.
