Unlimited, out of controll, mass production, realized in a few days or weeks, depending on size.

Lab created replica that simply attempt to “lookalike" a natural diamond !

Synthetic diamonds are mostly used to sell as real natural diamonds, usually with the intent to defraud!

Psychological fact: 

The difference between offering a real natural diamond and a synthetic replica:
Offering a natural diamond is a real festive experience!

Negative is the unromantic notion that synthetic diamonds are unlimited produced in some days or weeks, depending of the size.

View the reaction of the person who will receive a man-made, artificial  surrogate diamond, as a precious gift, whithout value.
What a disillusion. 
Not a real diamond, No investment value! 

Cheap! an imitation, usually without the intent to deceive but it will!

Try to resell it!
Comparable to buying a Rolex replica at $ 100. 
The quality is never the same and you will probably never be able to resell it.

Try to resell your replica at auctions by Sotheby's or Christie’s! No way!

Be aware, 
The actual price / value of man made diamonds: 
Prices are falling to zero value!

I have 2 large diamonds (over 5 carats) grown in a laboratory, of high purity (VVS1) and color D and E 
at a price off 80% of the cost of natural ones of the same parameters.

I want only 20% of the value of natural, 
even this is not the final price and is subject to negotiations!
