The more round the profile, the less the chance of chipping. I would not own a countertop with a "pencil" or "eased" edge, no matter how loudly my designer screamed. 1/8" minimum, and more at sinks.

You'll have to ask Enigma if Giza can be book matched, however, the movement seems to be fairly light so I doubt an un-book matched seam would be too objectionable. Better to redesign your island so a seam is unnecessary if it's that big a deal; you can get Giza as a jumbo slab.

Seams in light and white colored engnieered stone eventually get contaminated depending upon usage. Another reason for a smaller island and seam elimination.

Do not whine about the movement match in your seam please. Your fabricator is not a magician.

I would not "round" at all, but you only asked Joe.

Counter edges should suggest the REST of the kitchen. Shaker is crisp, and a square ease/polish looks best with it.

I've done this for years, nobody has chips, dings, nobody has gone to the hospital walking past an island corner.

As to book match? This is a gift from earth, not man, in consecutive slabs cut from that earth.

You have a quartz, faintly veined. MAN made. Cake batter. Show your layout, and where the concern for a veining match would be located.

Here below, photo barely visible.

I would not want a seam in this material in any island, even at the sink which is the shortest seam you can get..

Veins?

That issue is something you discuss at slab purchase with your layout, @ template in your home, and again at the fabricator. ........and know that even the best seam is not invisible, and a perfect alignment in veins usually impossible, though care can be given to a good look via cut at the fabricator.

Show your layout with the island that apparently exceeds ten feet.

The next time you get a chance, run your hand along the bottom of a pencil/eased edge at the dishwasher please.

Thanks for the replies! The kitchen is not mine, the question is on behalf of someone building a semi-custom home. I walked through a model with them, and noticed the seam on the island.

I agree that eased edge would look best. I have eased edge on my quartzite, having missed Joe's comments prior to my selections. I have chips, which is why I wanted to confirm before passing on the info about the profile.

It's good to know the giza seam shouldn't be too bad if there's too steep of an upcharge for the jumbo slab. Thanks for letting me know jumbo slab is a thing, @Joseph Corlett, LLC.

@JAN MOYER, the kitchen layout is set, they already signed off on it. They are excited about it, so I don't want to put a damper on it. I'm a little out on limb regarding the profile and seam. Do builders typically allow purchasers to work with the fabricators?

"Do builders typically allow purchasers to work with the fabricators?"

No. That's like you toddling into the Ford plant and asking for different wheels on your car.

Like the auto manufacturers, builders want as much repeatability as possible because it lowers risk. Lowering risk raises profits.

The builder "depends". Your own builder, as in a very custom home? Yes. A local to you semi custom is a maybe , and a production builder, in a setup such as you are just one in a series of a hundred homes ? Nope.
