Shirey explains the study of radiogenic isotopes hidden inside individual diamond inclusions to determine their age and hence the age of the diamonds themselves. This slideshow takes you through the processes Dr.
Shirey uses to select natural diamonds for research and extract the sulfide inclusions from them to obtain accurate ages—often in the range of billions of years. It involves ingenious solutions to fashion the tiny diamonds into plates for study, cleave out the sulfides, separate the isotopes of rhenium and osmium by chemistry, and count the various isotopes with sophisticated laboratory instrumentation for the final age determination.
Preparing the Diamond for Research
These diamond crystals, which bear sulfide inclusions decorated by rosette fracture systems, are suitable candidates for dating using the rhenium-osmium decay system. Shirey designed this jig for laser cutting the diamond crystals.

Preparing Diamonds for Study. I mentioned diamonds having detectable C14 as well as coal —I think I got that from creation. An evolutionist said you can easily find diamonds that have no C14, which is then evidence against a year old earth. The question is, how do I explain that? He takes C14 in diamonds as contamination and lack of C14 in diamonds as evidence against a young earth. How would you explain that?
What's the truth about carbon-dating
For all I know they all have C14 in them. Why would evolutionists ever look for C14 anyway? Please help if you can! These days, carbon 14 is continuously created as cosmic radiation converts nitrogen 14 into carbon 14 in the atmosphere.
Answers to Creationist Attacks on Carbon-14 Dating
Thank you again my brother, for using their own POOR understanding of knowledge and science against them. Posted by Claire in Scheepers Posted by NellyFrizzle The major problem with carbon dating is that its based on an assumption. Assuming that the amount of C14 and C12 in the atmosphere to be in equilibrium during the time the fossil in question was alive.
Now, like summer has kindly noted, you need to know how much C14 you are starting off with in order to make any calculations on its continuing half-life count down. The only way to do this is to take into account the ratio between the stable C12 and C14 and work your way down from there.
And we all know now that C12 and C14 are not in equilibrium stats And diamonds being pure carbon dated at the hundred of millions of years should not contain C The point is that all C14 should have expired and leave no trace, unless of course they are not in the millions of years age group. The "get into" impossibility means that it can't be contaminated or injected externally with C The only C14 in it are the ones present the day the diamond was formed.
Which apparently wasn't that long ago As for potassium, uranium and others of the same family of unstable elements for dating, they are all built on the shoulders of assumptions.
No. Carbon dating is a technique used to determine the age of organic material. As living organisms respire they take in carbon dioxide from. Can carbon 14 dating of diamonds prove a young Earth? I'm busy arguing on cellotonica.com about the age of the earth. The short answer is, “Carbon 14 can't be used to date diamonds because carbon 14 No matter how you look at it, you can't tell the age of a diamond by examining how much carbon 14 there is in it.
Do some research, all dating techniques spring not from a given fact, but an assumption. For example in potassium 40, it is assumed that no calcium or Argon were initially present Reply by Greg in NZ Have ALL diamonds that have been examined show significant C14 residues?

Or are they the exception to the rule? So far I have only found 1 reference to six diamonds tested from a Namibian mine, tested and funded by a creationist group, which whilst I respect their findings is not exactly unbiased sourcing. Put another way, if examining data on drug effects in the research base, you wouldn't include research funded by a pharmaceutical group for a product they sell.
Reply by Jason Wreight in Melbourne Carbon exists in a number of different types, called isotopes, which have different masses, depending on the number of neutrons in the nucleus. It has not been decaying exponentially as Barnes maintains. This idea [that the fluctuating magnetic field affects influx of cosmic rays, which in turn affects C formation rates] has been taken up by the Czech geophysicist, V. See Renfrew for more details. The archaeological ring sequence had been worked out back to 59 BC.
As for the other isotopic dating techniques, maybe you would care to share the links or state the articles which you feel make them suspect. That way we could all learn a bit more about it, as despite what you say, finding the credible scientific data for either side of the debate is tricky and not well laid out on either creationist or evolutionary sites.
