I think the marble naysayers have jumped on the bandwagon without really living with the stone. I have statuary in my bathrooms and love it. Most stains can be removed with a simple baking soda and water poultice. Acid etching is harder to deal with since it removes the polished surface, but its part of having a living stone in your home. If it becomes too bad, you can have it repolished. With a darker stone, you won't have as many issues as a white marble. In order to really know if you can live with it, I suggest you get a small sample of the stone and do some tests. Here is an example. http://www.dohiy.com/2013/04/21/marble-countertops-the-post-acid-test/ Please note that she used bleach and oxyclean to clean the stone after her test. Stay away from both since they can etch the stone just as much as an acidic food. Instead, clean with a ph neutral cleaner like isopropyl alcohol (rubbing alcohol), and for heavy stains, the baking soda poultice mentioned above. You have to remember that marble has been used for centuries as flooring, table tops, countertops, etc. throughout the world and most of these installations are still here and aren't stained and etched to the point that it has been ripped out and replaced. Just think about all of he luxury hotels in Europe and how many times they have been exposed to Hangover type guests without any damage.

Hi,  Go for Jet black granite for counter top. It would look classy with your white ceramic wash basin and beige wall tiles. And go for above counter wash basin.

quartz corean white synthetic marble any one as per your budget

It all depends on the budget you are looking at. As an architect i would give preference to granite over quartz any day. If your budget is INR 150-300 per sqft then go for south indian granites and if your budget is INR 500-1200 per sqft then go for Imported granite (Suggestions : Bianco Antico (in white), Blue Pearl (in dark blue-dark grey tone), Baltic brown : light+dark brown combination). As far as Kalinga quartz or any other brand quartz is concerned i find it not at all value for money, you'd end up spending INR 500+ sqft on something which is still in its experiment stage in India. The company is spending money on marketing and PR thats why new architects would promptly suggest quartz. I have heard enough complaints from home owners about quartz discoloration and bending. Fun fact : there is no warranty on any defects arising in quartz due to usage, which explains even the manufacturer of quartz dont want to take the responsibility of there own product. Reach me out if you need color advice for countertops. Thanks :)
