Remarkable facts: All diamonds are at least , years old. Many are 3, years old 3. How do we know this? Age: from Carbon dating? C-dating only works for very young carbon.
Larger pink diamonds are quite rare and currently very expensive. Natural blue diamonds contain the element boron Band this changes the conductivity of the diamonds. Natural yellow diamonds contain the element nitrogen N.
Clarity is decreased by the presence of blemishes or flaws, scratches, nicks, 'naturals' the original surface of an uncut stone. There are many systems of nomenclature.
Remember that in the first lecture we talked about how the proportions of a faceted gemstone are determined based on the refractive index?
It follows that carbon-dating cannot be used for anything that might have died more than about years ago. This clearly gives the lie to the statement that a supposed million-year-old fossil were dated by carbon-dating. Interestingly, some diamonds have been tested for carbon-dating. The diamonds are supposedly more than a billion years old. C-dating only works for very young carbon. You need to use other radioactive decay schemes (e.g., uranium-lead) to date inclusions in diamonds. Inclusions used for dating are around microns in diameter ( mm). "Carbon dating" properly called, no, for two reasons: The half life of C (which is the radioactive isotope of carbon used in carbon dating) is about years. This means that after years half of a given quantity of C has turned into other elements (specifically, nitrogen). In the next years, another half will be gone and so on.
Review the basic concepts: Refraction is dependent upon the wavelength. Fire ,which is seen as rainbows and glints of color, is due to dispersion a consequence of the placement of faces on the crown to take advantage of the prism effect. The brilliant cut modern round brilliant cut or Tolkowsky cut is a typical cut chosen for diamonds.
There are many alternative diamond cuts.

A poorly cut stone is characterized by poorly chosen proportions poor optimization of brilliance and fire or, worse still, leakage of light from the pavillion. Misplaced facets, extra facets, and problems at facet junctions are also characteristics that reduce the quality of "cut".
Review the light path in a correctly cut gem! Other issues: Treatment, simulants, synthetics Treatments: filling of cracks Surface cracks and cleavages reaching the surface are often filled with a glass-like material.
Solutions can be poured into the resulting "hair-width" diameter hole to bleach colored inclusions. This is comparaed to getting a filling in your tooth. A common color produced by irradiation is green. Early attempts: beginning of 20th Century: diamonds exposed to radium - the problem was that the diamonds remained radioactive! However, modern irradiation treatments do not produce radioctive stones.
Irradiation involves the use of devices such as: linear accelerators gamma ray facilities nuclear reactors Detection of irradiation treatment: Electron irradiation only changes the surface of the stone.
Thus, it produces a concentration of color where the gemstone is thin.

Nov 07, Eight of the diamonds yielded radiocarbon "ages" of 64, years to 80, years. The ninth diamond was cut into six equal fragments, which were each analyzed. They yield essentially identical radiocarbon "ages" ranging from 69, years to 70, years. Carbon dating has a certain dating of error, diamonds depending on the age diamond material of the sample used. Carbon diamonds a half-life of about years, so researchers use the process to date biological samples up to about 60, years in the past.

Dating the rate carbon decays has been consistent, any carbon older thanyears is undetectable by current measuring techniques. But carbon has been measured within natural diamonds. Either the decay rate of carbon is not uniform, the diamonds are younger than believed, or both.

C-14 in Diamonds: Carbon Dating Disproves Evolution?
Thank you again my brother, for using their own POOR understanding of knowledge and science against them. 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.
Seems excellent carbon dating diamond consider, that
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. 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 Have ALL diamonds that have been examined show significant C14 residues? Or are they the exception to the rule?
