Diamonds have been found all through the ages, dating back to the Pharaohs. Basic diamond cutting was available even earlier then the 16th century, just not the many facets you see today.
I apologize-I do not have my books handy, or I could give you a clearer history.

THLord Stefan li Rous asked:
>What do concentrations of chromium diopside and pyrope garnets have to do with
probability of an area containing diamonds? Are these simply a common
side-effect of the processes that also create diamonds?
Everywhere that diamonds are found, chromium diopside and pyrope garnet are also
found. That doesn't mean that the presence of diopside and garnet mean there
are also diamonds, only that the three are frequently found in the same
location. Locating the heaviest concentration of the red and green rocks means
it is more likely that the pretty clear ones are near by.
>Were you using "ant-hill" sized samples or were you specifically choosing
samples from ant-hills?
The ants, dear little workers that they are, are capable of much . but there is
a limit to the weight such a small body can pack. The bigger rocks must be
worked around but the rocks in the ant hills that are small enough to move, they
pitch over the edge of the hole. Wind winnows out the fines at the surface.
The ant hill is therefore a collection of whatever smallish pebbles that
comprise the surface layer of the ground and a good sample of what sort of
material is in the area. The sample, therefore, was a selection of rocks found
in the ant hills.
Do we know what areas diamonds were found in, in period? Since faceting of
jewels was a late period invention, did diamonds even rank high on the scale of
precious gems in period?
As to where Diamonds were found in period, my research was concentrated on an
eight 64 mile square of Otherhill Artemisia . mundanely southwest Wyoming. The
grant was to search an area of known to have kimberlite. Kimberlite is the
matrix material that produces diamonds. The stones found in the research
project are all about the same size as one might find in ant hills. They are as
nature sends them. They are rather pretty tied in with silver wire.
