“Advanced dentistry techniques allowed Native Americans to inset gemstones to their teeth as far back as 2,500 years ago. The early dentists used a drill-like device with a hard stone such as obsidian, which is capable of puncturing bone. The ornamental stones—including jade—were attached with an adhesive made out of natural resins, such as plant sap, which was mixed with other chemicals and crushed bones.”

Awesome.
