Howlite is commonly found as carvings, or in jewelry. It is a porous mineral, easily dyed to look like turquoise because of the similar look of the veining patterns. Dyed howlite (or magnesite) is marketed as turquenite. Howlite is also sold in its natural state, sometimes under the names "white turquoise" or "white buffalo turquoise," or "white buffalo stone" (none of which are true turquoise).
Honey Onyx is a delicate, soft stone often used as a decorative and architectural stone for kitchen countertops, bathroom sinks, and as stone sheets and tiles. It is particularly beautiful when back lit.
Travertine is a sedimentary limestone deposited by hot mineral springs or in limestone caves ("flowstone"). It is sometimes marketed as travertine limestone or travertine marble (it is not a marble). Travertine is often formed in creeks or rivers, or in caves as stalagmites and stalactites. Sometimes flowstone cave structures are deposited into thin sheets called "draperies" or "curtains" with brown and beige layers that look like bacon--often called "cave bacon."
