Sapphire is not an insulator, as it is a type of corundum crystal that exhibits good electrical conductivity due to the presence of impurities. Sapphires are commonly used as semiconductors in electronic devices and have applications in optoelectronics due to their transparency and durability.
Both sapphire and ruby are a crystallized form of the compound aluminium oxide which is a good insulator.
A ruler is typically made of plastic, which is an insulator. This means it does not conduct electricity well.
Velcro is an insulator, meaning it does not conduct electricity. It is made up of nylon or polyester fibers which do not allow electricity to flow through them.
A magic one is an insulator.
