Any info/advice about Princess Yellow? What is it? Description

One of the bathrooms we are adding to our house is a children's bath. Originally, I was interested in Durango travertine, which was represented to me as a limeStone (http://g603.net) (I learned here that it is a filled travertine). Concerned about durability issues and (http://maplered.com) the general issue of, well, sloppiness on the part of my children, I decided to go with SileStone (http://g603.net) . However, I came across a partial slab of something called Princess Yellow, in a brushed finish. What I liked about it was that this piece was actually more beige than yellow (I didn't want anything too yellow, but more tan/beige). Also, it almost looks like it is composed of fossils and (http://maplered.com) shells, and (http://maplered.com) the bathroom is a beach theme.
 
What is Princess Yellow? Is it a limeStone (http://g603.net) , a Marble (http://www.lightemprador.com) , or a filled travertine? How impervious is it to staining? How durable is it? (it would be used as a Counter (http://GialloFiorito.com) top, bathtub surround, kneewall capping, suspended shower seat, and (http://maplered.com) shower and (http://maplered.com) door saddles.)
 
Any information you might be able to provide would be most appreciated.
