Marble.

It scratches glass. I have not been able to get a sample yet.

White Macaubus, or mustang, Or Giotto

All quartzite's

Looks similar to these slabs that I saw last week at a stone place. They called it Macubus Giotto.
For pricing comparison, the fabricator I was at had this priced in price group 6.

Other stones in the same price group included Tajj Mahal, Blu Venatu, Shadow White, Shadow Storm, and Perla Venata.

I have heard some people say that Shadow Storm is not a quartzite. When I looked online, some companies have it listed as marble and some as quartzite, so it is probably softer like a marble.

It is very close to Giotto Macaubus, except it is more white than gray. Still no sample. They will not cut a sample until their work orders are done. They keep getting more orders though.

Calacatta quartzite. This might be my stone.

I have not had a discoloration problem on my Sea Pearl, thank goodness. That would drive me nuts to spend that much money and have it discolored. I am trying to learn everything I can about stone.

It looks just like mine. Mine was called Opus White. I’ve lived with it for a year and absolutely love it, totally bulletproof, definitely not marble!

Mine has grey-green veining too.

ILoveRed, you are right. Your Gioia is very close.

I just found a post about Calacatta quartzite and Macaubus quartzite.

"Many people here have calacatta quartzite and macabaus quartzite- which is the same stone, depending on how you cut the stone you will see different veining. The calacatta version has random veining and the macabus shows more parallel stripes."

I never thought about that. I am trying to talk the owner into going back in their records to see exactly what that remnant's name is. I can talk to the fabricator or the office staff, but that is it. No one calls me back or returns my emails. I can't even get them to tell me the thickness of the stone.

Thanks, Ephma. I will look for it.

I have been looking in the past few weeks for quartzite and I saw this at a few locations. In my opinion, it is Calacatta quartzite. It was one I was considering so I looked at it many times.

Thanks. That looks like it is the one.

Still no sample of the stone. I call every week, and they say they are too busy. I found a scrap piece that would not work for a countertop, but I can't get them to cut a piece off. It is about 12" deep. I can't get my floor tile done until I have a sample of the countertop. I guess I will have to find another stone yard. Next closest one is an hour away.

A better picture...top part is the floor tile I was considering since I couldn't get a sample to match the dark gray-green grain.

I finally have a sample. I tested it again on a glass tile, and it scratched the tile again.

Lemon juice test is tomorrow.

Karen, what are the black specks? I think this is an Intermediate quartzite, but it does have some crystals. It also absorbs up to the waterline, but dries out quickly.

I used different edges of the stone to scratch glass, and it passed every time. No etching from lemon juice or vinegar.

Bathroom stain test. Left to dry overnight. Clockwise starting with black spot: Mascara, liquid makeup, tinted moisturizer, water (below black), red wine vinegar, mustard, and lemon juice (top right). I left the puddles on pretty thick. I will never have mustard, etc in the bathroom, but I tested them just for giggles.

The red wine stain is on the far left and barely visible. The mascara and makeup stains are probably because of the oils.

After washed with Dawn.

Water absorption test after 15 minutes. The watermark only goes up to the water level. It dried after 15 minutes. I circled tiny black specks that look the same as the veins.

Peke, did you end up installing this stone? If so, how do you like it? What did the fabricator use on it? Do you have any finished photos? Thank you!

I found the stone January 2020, so 17 months ago.

I still can't get a plumber to show up. The newest plumber said he would be here this week, but he just canceled. They find bigger jobs.

So, until I get a plumbed out, I am stuck.
