Can carbon dating used diamonds

We’ve traveled to the Carnegie Institution of Washington—more specifically the Institution’s Department of Terrestrial Magnetism—to document Dr.Shirey’s work on determining the age of diamonds from many mines around the world by analyzing the tiny mineral inclusions preserved within them. Steven Shirey, a senior scientist at the Carnegie Institution of Washington’s Department of Terrestrial Magnetism, has a special interest in diamond—it’s his best method of glimpsing the unimaginable pressures and temperatures of the deep earth’s interior.Willard Libby discovered radiocarbon dating in the late 1940s.He received the Nobel Prize in Chemistry for this discovery in 1960.

For example, when the Dead Sea Scrolls were dated, three methods could be used: 1) Dates written in the documents themselves (like the date at the start of a letter) 2) Paleography, which uses the style of script used to write documents to date them, and 3) Carbon-14.Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure.It is sometimes thought possible to extend the dating range a few half-lives, so one occasionally sees dates as old as 70,000 years or more.This can be done very accurately, although some samples may be difficult to work with.Beyond this, the accuracy of the date depends on the reliability of the assumptions used in interpreting the measurements (see below).

C14 has a half life of 5730 years and is only good to date objects to 50,000 years or so.
