crassulaceae is the family name for all sedum, echeveria, crassula, aeonium, graptoveria etc. That image is actually x Graptoveria amethorum, described as "One of the more delicate Graptoveria hybrids, This plant is slow growing and has moderate watering needs."

I am leaning toward a Graptosedum hybrid because of the thick rounded leaves but still not sure.
