Actually laser inscripton on high quality genuine diamonds is not noticible. It iis so small that you are unable to see it with out a loupe. Even then it is difficult to read. It would come in handy if your diamond was stolen.
No, diamonds in general are not as rare as some retailers would have you believe. However perfect fiamonds are.

synthetic diamonds are the reason why proper certification has become more & more important for the industry. people who spend money on gems don't want man-made ones, they want the real stuff. By the way, natural diamonds come in many colours (pink, green, yellow, whatever). Yellow diamonds are indeed a result of nitrogen.
Because these "fancy color" diamonds became so popular, tricks were developed to color gems artificially (they're much less valuable though, expert know tricks to see the diff). Synthetics are widely used in many industries (medical to aerospace), due to their extreme purity and their optical and thermal qualities - they're actually much more perfect than natural ones. But they're very unlikely to become competition for the jewellery business...
