Engineered stone, made almost wholly from quartz crystals (and often simply referred to as quartz), has the advantages of natural stone and a few others.

For example, quartz does not need sealing, polishing, or reconditioning and is stain- and heat-resistant. It is a natural product, but unlike wood, it does not absorb moisture, which can foster the growth of bacteria. It is so hard that only a diamond or other quartz crystals can scratch it. It is also so strong that it can span 36 inches or overhang 12 inches without support. And because it is made up of many tiny crystals, its surface is reflective, adding an elegant touch to any room.

Available in a range of colors, from neutrals to brights, quartz works well with a number of materials including glass, metal, and wood. However, its price usually limits it to high-use installations such as kitchens and baths.

Quartz is manufactured in sheets 52 by 118 inches—large enough for a generously sized L-shaped counter. Countertops are cut to exact specifications and often come with pieces for a backsplash. If your installation requires more than one sheet, plan to put the seam in an inconspicuous area because it will show.

A lesser-known type of engineered stone is synthetic slate, a fiber cement–based product. Like quartz, it is harder and stronger than natural stone, is heat-resistant, and can be repaired. However, it absorbs moisture and therefore requires regular sealing. It comes in four colors.
