Quartzite is a naturally occurring metamorphic rock. It is harder than granite. It makes a great countertop. "Quartz" countertops as they are often referred to - are a manmade product - consisting of about 93% natrual quartz stone that is ground up, color added and a resin binder added to hold it all together and make it nonporous. Quartz countertops are manufactured under a variety of names such as Cambria, Caesarstone, Hanstone, Silestone, Zodiac and more. They also make great countertops. These two products are completely different!

Under cabinet lighting is a great addition and if you have an island some great hanging lights over this all help to highlight the counter. With kitchen lighting the more the better so pot lights to give overall lighting, you don't want shadows in the space. A good lighting designer can be very helpful, most lighting stores have one on staff.

Take a look at Caesarstone in the London Gray color. It resembles marble but never has to be sealed and has a lifetime warranty. I have it in my kitchen & love it.

Interesting, do you find that the shine on the quartz dulls after time?
