Lab diamonds are man-made diamonds which are created in a laboratory. They have some of the same properties as natural diamonds, such as purity, lustre and thermal conductivity, but they don’t undergo any natural formation processes during the formation of these crystals. Though lab diamond prices are usually very high compared to real ones just because it is also purer and has better clarity. The process to make man-made diamonds is a long and expensive one with several steps that involve dozens of steps each.

What is a lab diamond vs a real diamond?

Below is some information to help you understand the lab diamond vs the real diamond.

1. Lab Diamonds will Cost Much More.

Lab diamonds usually cost more than their natural counterparts because they are considered to be purer and better quality. While natural diamonds go through processes that allow them to be formed millions of years ago, lab-created ones are created in a laboratory under controlled conditions.

2. Lab Diamonds have a Higher Refractive Index.

The refractive index of lab diamonds is usually higher than that of real ones. It measures the way that light bends in the diamond which gives them the brilliance for which diamonds are famous for.

3. Lab Diamond won’t Last as Long.

Because lab diamonds are made in a laboratory, they don’t last as long compared to real ones. If you compare the 100 years of life that a natural diamond can have and the 20-30 years you get from lab diamonds (this is normally the exception), it’s easy to see why their price is high.
