Then, are real diamonds real diamonds?

Synthetic diamonds are made by humans in a lab. However, genuine diamonds are mined from the ground and created by nature. If the lab creation is good enough, it can be difficult to tell the difference without expert knowledge and testing methods.

Secondly, how can you tell if a diamond is real or fake? A fake diamond will let the black shine through, and you may even be able to read a word depending on the size of the fake stone.

2. Rub sandpaper against the stone.
3. Do the fog test.
4. Hold it in the light to see how it sparkles.
5. Look at the stone's refractivity.

Beside this, what is the difference between CTW and CTTW?

CTW refers to the carat weight of a single diamond: just the individual weight in carats of one, single gem. CTTW refers to the total carat weight of multiple diamonds. The carat total weight of these pieces will tell you the total carat value of all of their stones put together.

What are fake diamonds made of?

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.
