Diamond hunting.

I am currently into hunting gemstones and diamonds.  I have concluded that diamonds may be easier to find than gold.  With gold the source of the gold is always looked for.  With diamonds the source is know first.  Gold settles clear to bedrock.  Diamonds don't go clear to bedrock.  Diamonds are found in pea gravel.  Finally, gold is small.  Usually gold is the size of grains for even flour gold.  Diamonds can be much larger.  That makes three reason why I fell that diamonds are easier to find than gold.  They are the source, location in the placer or lode and the size.
