Is this a crack or a vein in my granite

[Ridingthegravytrain]

I had new granite fitted yesterday. Upon inspection I noticed this. I can feel it all the way along with my nail so I believe it is a crack

The supplier are telling me it is a sugar vein

I thought veins were within the granite and therefore shouldn't be felt on the surface, especially once it was polished and sealed

Help!

Looks like a crack to me. I think it's similar to my cosmic white and I can't think of any similar lines on mine like that. It's definitely 100% smooth.

If you can feel it with your nail on the surface then it’s a crack, the surface should be smooth.

Get the gutters back and stick to your guns about not being happy with what they have provided.

Not gutters, fitters ffs!

Thank you for your replies. I have emailed them back and will wait to see what they say

to clarify a vein shouldn't be felt as an imperfection on the surface should it?
