Marble counters, being porous, stains easily. But, if you use a commercial grade sealant and be careful about the spills (anything acidic) and can cleanup as soon as it happens, it looks good on the island against the black granite you have.
Chandelier over island will look good, but 2 might be an overkill, then again depends on the size of the fixtures...

Search on quartzite contertops on Houzz. You'll see some beautiful examples that look a lot like marble, but quartzite is about the hardest, most durable countertop you can buy. I just had my island done in a dark quartzite and it's amazing. Light quartzite is more common and it sounds like that's what you are after. It's pricey, but well worth it.

Marble with a honed or leather finish (not polished) that has been sealed will perform beautifully in a kitchen. You will need to reapply a sealer 2-3 times a year and as mentioned above, you will want to be mindful of things that can stain and wiping in a timely manner. As long as you are aware of the proper care and maintenance which sounds much worse than it is, you shouldn't be afraid to use it.

Love Quartzite/quartz but its way to $$$ for my kitchen. When I retire then ill do all the things I couldn't do with kids! But having two kids eating and doing homework at the island I don't want to be stressed out that they've got some mustard we didn't see on the marble until 4 hrs later. I love the look, has anyone done marble on 3/4 leaving the last 1/4 for a butcher block? What kind of wood would be great for a butcher block and is it sealed to the marble or is the wood layed on top? Almost "fitted" onto the marble. Think removable cutting board. Hmmmm actually I like that idea. Best of both worlds. Make the wood moveable up and down the island.??? Thinking out loud.

Marble stains granite that looks like marble dose not ! So go with the look you like with out the problems I say ! Look at everything that has the feel you want but easy care. Normally people don't know what real marble is any way and other materials have the look of real marble with easy care. I like no added patina from the day I put in a kitchen. I would also go with one big chandelier for a lux look unless your island is over 8 feet long. It's not. Possibly 2 smaller ones. I would hate having red wine stains on a new kitchen counter. Even sealers are a pain to keep up with. For a country french look a wood counter that is dark wood and beefy 6" thick top would look great with a crystal Chandelier. I would want all the same surface on the island to use as a buffet when I had company. If the dining area is in the same room I would get a even bigger chandelier matching over that table. Of course pics would really help out in these questions. I would also not get a solid black counters for the rest of the kitchen, but something with a speck of white or gray. I have had black counter tops and they showed every speck of salt, flower, sugar etc. I'm a bit OCD in a Kitchen and bath wanting them to always look spotless. Who am I kidding I like everything spotless. lol And always have even with kids in the house & their friends.

If you like the patterns of marble and granite and do not want to deal with care and maintenance of natural stone, quartz counter top is probably a better choice. There are many quartz manufacturers and many patterns available. Cambria makes beautiful marble like quartz counter tops which are much easier to maintain than marble (cambriausa.com). Good luck with your kitchen project!
