Agglomerates (see also Terrazzo further down.). Shiny Looks like Terrazzo, but the marble/quartz chips are in a polymer resin marble dust binder. Also known as "composite engineered stone" Silestone and Ceasarstone are in this agglomerate category because they are over 90% quartz chips and dust with a polymer resin binder.. Terrazzo tile is a cement binder, not polymer resin see below
