CBD crystals, or isolate, is the pure form of CBD. Other types of CBD include broad-spectrum CBD and full-spectrum CBD. These forms contain low levels of various other cannabinoids, such as THC. They may also contain terpenes, which give many plants their scent.

CBD crystals only contain CBD.

There are multiple ways of extracting CBD from the cannabis plant, including steam distillation, carbon dioxide extraction, and solvent extraction.

The resulting product often contains various compounds from cannabis plant, including low levels of THC, but this depends on the plant source. At this stage, the extracted CBD is either full-spectrum or low-spectrum.

Manufacturers then refine the product further to obtain CBD isolate, or crystals.

The refining process removes all non-CBD compounds from the product, leaving behind pure CBD in a crystalline solid form. Usually, producers grind up the crystals for sale or use them in other CBD products.
