Quartz resists cracks and chips, but they are possible if something heavy and sharp falls onto it. Minor damage can be repaired very acceptably.

Cracks Caused by Stress
If your countertop is fastened too tightly or in a way that causes torque on part of it, this might cause it to crack. The first thing to do to repair a stress crack is to relieve the pressure. Find the fasteners underneath that are the closest to the crack. Loosen then slightly. The countertop fasteners and brackets should be snug without being loose or too tight.
Your local home improvement store should have a chip repair kit for quartz. Most of them are two-part epoxy kits that can be tinted to match your countertop. Follow the directions carefully to adequately prepare and fill the chip and remove excess chip filler before it hardens. With care, a chip or small crack repair can be done properly and be hard to see.
Step 1: Read the directions completely to get an overview of the project.
Step 2: Prepare the damaged area as indicated. It must be very clean to allow for good adhesion.
Step 3: Pour out some of the epoxy and mix in tint to match your countertop color.
Step 4: Use the included applicator to apply the repair material to the chip or crack.
Step 5: Use the hardening agent, if one is included in the quartz chip repair kit.
Has a corner broken off your quartz counter? You’ll probably be able to glue it back on with the same epoxy material used to repair chips or something similar. Clean the surfaces that will bond together, apply the glue and press the piece into place. It is important to remove excess glue pretty quickly
This is something to keep in mind as you consider quartz. Because it is an engineered material containing resin in addition to quartz crystals, it is notoriously hard to polish if the factory finish is marred. In fact, many countertop repair contractors won’t take the job or will ask you to sign something stating that you know that a finish that looks factory-fresh cannot be achieved.
The problem is that the resin begins to melt at high temperatures – the kind of temperatures required to polish stone properly. So, for example, if something extremely hot scorches the surface, trying to polish it will result in a cloudy finish.
Keep in mind that quartz offers decent heat resistance, but is not as good as natural stone in this regard. Use hot pads and trivets, and keep your hot hair tools away from the kitchen counter!
