I'm curious as to why you are choosing a black mosaic without having a plan for the rest of the space, or have you moved into a space with an existing black floor? I think it would be hard to keep clean, since with mosaics there is a lot of grout. For a jewellery store, it's important the goods for sale are presented in an elegant way. You really must consult an interior designer to put a plan together for you which will also include a lighting plan to highlight everything.

you can go for vitrified Italian tiles

Hi Saranyam, You can use tiles/granite for kitchen and bathroom, while for the living room and other rooms you can select marble flooring. Marble is more durable than tiles as they long for some 25 years while tiles stay for 10-15 years. Also, Marble is stronger than tiles. But for areas such as kitchen and bathroom tiles are used because in case of stains the floor can be easily cleaned whereas marble absorbs the stains which becomes difficult to clean afterwards.
