Assembled gem
An assembled gem is a gemstone made up of other smaller gems. An assembled gem can often be a fake gem with a desirable piece of gemstone attached to pieces of inexpensive imitation gemstones. For example, a combination of a thin layer of green glass and a colorless piece of quartz would be a composite gem.Types
