What are geographical conditions where diamonds can be found?
The conditions are not so much geographical as they are geological. Since diamonds are erupted to the earth's surface by a specific type of volcanism with other trace minerals, geologists look for these trace minerals. Kimberlite is a rock produced by this type of volcanism, and is where diamonds are found in, or eroded from. Only about one in 200 kimberlite-trace-mineral sites include diamonds.

Diamonds that are made in a laboratory are known as lab-grown diamonds . These diamonds are considered minerals since they are optically and chemically similar to mined diamonds, formed by the same mineral known as carbon. The only difference between mined and lab-grown diamonds is where carbon is crystallized- the earth's crust or the lab. CVD diamonds look exactly like mined diamonds and sparkle like natural diamonds, which is why they are known as minerals. There is no chemical or visual difference between lab-created and mined diamonds.
