Rocks, Cabs, Slabs...What is the difference?


Here is a great photo of all the different "rocks" that I describe when I'm talking about making jewelry. From the left going clockwise are Slabs and this photo includes Mookaite, Dinosaur Bone and some small pieces of Lapis. Larger rocks are cut up into more manageable pieces called "Slabs". They range from 1/4 - 1/2 in thickness and are in various sizes depending on the rock they were cut from. Top is a Dinosaur Bone and a Turquoise rock that slabs have been cut from. Rocks vary in sizes and have to be cut into something more manageable for cabs. Cabs are short for cabochons. The box has various cabochons and they are made directly into jewelry. They have been shaped, ground and polished and are ready to set. This shows some Turquoise, Dinosaur Bone, and Variscite cabs. It's definitely a process to select stones and cut them into various sizes to be eventually set into jewelry.
