Musse4936, you're posting objects that one would find in most all the tourist shops in a Chinatown. Trinkets a tourist might bring home as a souvenir from their vacation. Usually costing only a few dollars and often misrepresented....
If that is the market you are in, I'm sure there are many other shops in the Philippines with similar wares. Do your homework. Research what others are selling and how it is being represented and the prices it is being sold for and how negotiable those prices are.
That's YOUR job, not ours.
l have never seen a vase like this in manila, the vase comes from japan. l know the women who import it...
to get marble rule out drop a little hydroelectric acid (use Gloves and Goggles and take safety measures) if you see chemical reaction ( you will see bubbles) marble is composed of calcite (metamorphic) so it reacts with cold, dilute, hydroelectric acid.
Thanks for your help, here are pic. of the test l just did.... and some more close up pictures, hope this help... the bobles where there for a while 5 min. then clear like water... l used Hydrochloric acid...for the test.

It is aragonite, which some call marble onyx. It is relatively soft and easily carvable. Availabvle in Gift Shops all over the world.
Data: Cleavage: {010} Distinct Color: Colorless, White, Gray, Yellowish white, Reddish white. Density: 2.93 Diaphaneity: Transparent to translucent Fracture: Sub Conchoidal - Fractures developed in brittle materials characterized by semi-curving surfaces. Habit: Fibrous - Crystals made up of fibers. Hardness: 3.5-4 - Copper Penny-Fluorite Luminescence: Fluorescent and phosphorescent, Short UV=green,yellow white, Long UV=green, yellow pink. Luster: Vitreous (Glassy) Streak: white
So, in the future, how would you go about positively identifying this material and separating it from jade or quartz, musse?

i am glad that you performed the test and specially used safety measures with Acid, washing with Water was great idea for Neutralizing the acid.
now you know what you have and you learned a very effective way to separate marble onyx from Jade or quartz rocks

a simple soft polish would make it disappear

YES, Banded aragonite can be referred to as travertine. Or banded aragonite, you smartie pants!
True & True, both Barbras are right and smart, as you said people are more familiar with marble onyx.
