There are a lot of man made industrial diamonds, for diamond paste on drills and such, it is pretty easy to make sub millimeter sized diamonds on an industrial scale.
If large diamonds could be made cheaply enough, someone would try to get away with selling them as natural, you can take that to the bank, detectable or not. If they sold some of those diamonds to a diamond merchant for cash, how long do you think they would hang around town?

I would gladly buy an artificial manufactured diamond for a fraction of the normal price if not even I can see the difference, nor my girlfriend.

Take a look at this link, monster sized diamond engagement rings for 500 bucks and under. It looks like a 10,000 dollar diamond, but they are real diamonds, only man made.

your girlfriend can take it into any jeweler, and they'll appraise it for her at $500 bucks, instead of $10K.

the fine print says they're selling "diamond simulants", not synthetic diamond.

http://en.wikipedia.org/wiki/Diamond_simulant

The high price of gem-grade diamonds has created a large demand for materials with similar gemological characteristics, known as diamond simulants or imitations. Simulants are distinct from synthetic diamond, which unlike simulants is actual diamond, and therefore has the same material properties as natural diamond. Enhanced diamonds are also excluded from this definition. A diamond simulant may be artificial, natural, or in some cases a combination thereof. While their material properties depart markedly from those of diamond, simulants have certain desired characteristics—such as dispersion and hardness—which lend themselves to imitation. Trained gemologists with appropriate equipment are able to distinguish natural and synthetic diamonds from all diamond simulants, primarily by visual inspection.

The most common diamond simulants are high-leaded glass (i.e., rhinestones) and cubic zirconia (CZ), both artificial materials. A number of other artificial materials, such as strontium titanate and synthetic rutile have been developed since the mid 1950s, but these are no longer in common use. Introduced at the end of the 20th century, the lab grown product moissanite has gained popularity as an alternative to diamond.
