I don't have pics, but we'll be installing a DIY slab of Piracema in our
Master Bath. The slab we reserved is gorgeous, with light green and
beigey/white veins. The heavy veining is just why we like it!

Barroca, which used to be called Black Venata, has lovely white veining.
It too is gorgeous!

Greetings fr RI. Sorry but i dont have access to fotos right now as i am actually writing from NY
In our 1900's cape style cottage, we have used Piracema 12x12 tiles and Piracema slabs for some counters. However, NONE are in the kitchen so they are not oiled (eg not black). Chose Piracema for the grey blue-green shades and liked for these small applications (explained below) the interest of the speckles etc. The color has worked beautifully in brite day lite, nite time electric lighting and on cloudy days,...obviously more blue in some situations, but never dull
The floor tiles are used in an indoor entryway to a stone patio, and that entry way is part of a large dining area...as the transition drip-stop before walking on the wood floor or oriental carpet. While there was concern that soapstone in general,and Piracema in particular, are 'soft' and show Talc scratching, after 4 years, this is not the case. Of course we are not dragging our cleats, or Yaktrax over it! Not far and off of this same room, is a powder room bathroom, tiled the same. The room has, BTW, a Toto pale gray (almost a gray blue) commode, and sage green tile on part of the walls...the colors work well together. We chose the tiles after reading that they are not slippery, and this has proven true. HOWEVER, soapstone tiles dont dry out as fast and that is particularly so on humid days.
The counters are in the same dining room and flank each side of the that exit door, serving as a bar and storage area. Again, these are not oiled and one has an undermount large st steel sink, and there are walnut simple shaker style base cabs, and glass doored walnut cabs above. The colors work very well together, as the gray is not too gray for the walnut and light enuf to show nicely. The edges are finished with a soft qtr round at the top and bottom so that they are not knife edges but softer to the touch. In the four years using the sink alot for water and to prep beverages or wash hands, the counters have not stained or darkened.
As for use in the kitchen, one would like end up over time or at the outset oiling the counters to a dark finish and yes, with the Piracema, more veining and elements are likely to be part of that (vs the matte black even look)
Best of luck Hope this helps. Sorry i cant send fotos now but if you want, i can at beginning of March
