Gem Diamonds was created in 2005.
Brown diamonds are the most common colour of diamonds mined, of gem-quality. Only about 20% of all diamonds mined are of gem quality.
There are several reasons why a natural, gem-quality diamond is costly, the foremost being it's rarity. Only about 20% of all diamonds mined are gem-quality. Also, lab-created diamonds are less costly that natural diamonds. Industrial quality diamonds are not costly.

Generally, a gemologist is trained to identify the differences if the diamond is promoted as a gemstone. But basically, natural diamonds possess unique colour and clarity features generally not found in lab-created diamonds. Lab-created, gem-quality diamonds are limited in the colour and general maximum carat size that can be produced. You can read more, below. Most lab-created diamonds -- as is true with natural diamonds -- focus on industrial quality production, not gem quality production.
Diamonds come in all sizes: 20% of which are gem-stone quality, the remainder are industrial diamonds. Most diamonds are tiny: gem-stone quality diamonds must be larger than most diamonds found, because of their use. Gem-quality diamonds must be visible, which is not true for industrial diamonds. Your answer, then, by logic, dictates that most diamonds an average diamond is much smaller than a pea.
Diamonds are best identified by a probe that tests the conductivity of the gem.
