Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

All about Diatomite and Travertine Properties
Know all about Diatomite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite and Travertine belong to Sedimentary Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Travertine is Banded. Diatomite appears Soft and Travertine appears Fibrous. The luster of Diatomite is dull while that of Travertine is dull to pearly. Diatomite is available in grey, white, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
