Advantages Include: unique appearance, ability to be backlit for dramatic effects, and a seamless aesthetic when installed as large panels or slab surrounds.
Trade-Offs: Onyx Is Softer And More Porous Than Granite Or Quartz, Demanding Proper Substrate Support, Sealing, And Care To Avoid Scratches And Staining.
