As you can see, it's definitely brown and not a dark gray or similar.

I would be disappointed with that. I would send pics to the mfr/installer. It may be possible for them to chip that out and replace it with some resin.

Well yeah, sometimes stone and fabricated stone can have some variations in it- one fleck isn't out of the question. Did you pick the slab that the countertop was cut from?

There's disclaimers for this reason that read like this:

"Buyer/Owner must determine slip resistance suitability and maintainability.

These products inherently lack uniformity and are subject to variation in aesthetics, color, shade, finish, tint, hardness, strength, resistance, density, etc. Some products may be characterized by dry seams, pits, and fossils. In polished and honed stones, these pits are often filled during the manufacturing process or at the time of installation. These fills can occasionally pop out from normal wear and use. In these instances, it may be necessary to refill these voids as part of a normal maintenance procedure.

Do not use abrasive sponges or cleaning agents with strong chemicals as this may harm the metal mosaics."

Is there no way to tag a Houzz user to bring this post to their attention? I'm ***really*** hoping Joseph Corlett sees this as I've been browsing quartz issues and from his comments he's clearly an expert. Someone please help me get this to Joseph?!?

He will be along if not tonite, tomorrow am for sure.

It's an easy fix.

Really? The fabricators are saying there's nothing they are willing to do. I'm so upset. I know it sounds dramatic, but we saved 11 years for this bath reno and this is already the second top they've brought. The first was cut so badly there was room for an entire shim along the wall line. They took that piece (which didn't have a brown fleck) back and sent this, and it really stands out to me. They're insisting these flecks are "all over" the color I chose, so I called and emailed the supplier and even visited the supplier - who I happen to be using in my granite search for my kitchen - and the supplier said it's not the case and they don't understand why the fabricator didn't plan to adjust and cut it out. The fabricator has a terrible attitude and I'm assuming since this is a "small potato" job for them just doesn't care. If there's an easy fix, can you possibly recommend someone you know and trust in NJ?

Should I push back and demand a new piece or for them to fix it? I'm just so annoyed because if they didn't botch piece 1 this piece wouldn't even be here. Btw, botched piece 1 was a drama to get out, even with me standing there with a shim in the jagged cut along the wall. They were telling me my wall is crooked. Second template they somehow realized my wall isn't crooked. I just don't see these people as helping without a fight. Thank you for any of your valuable insight!!!

Resin pooling. Not considered a flaw by any manufacturer, so not actionable. Yes, it can be drilled and filled. Probably for a fee, since there’s not a lot of goodwill there.
