Characteristics Of Fancy Cut Lab Diamonds
The process for cutting and polishing lab-grown diamonds is the
same as for mined diamonds. Similarly, the testing and grading
process is the same and carried out by the same laboratories. As
such, they are indistinguishable on both an aesthetic and molecular
level.
Diamond mining and laboratory breeding way is the only difference
between diamond source, mining diamonds are created by billions of
years ago, need a large number of mining operations from the earth
to dig out, but the laboratory breeding diamond can be built
through controlled process in the lab, reducing cost and energy
consumption, eliminate the negative effect on the local environment
and society.

Prospects And Advantages Of Lab Grown Diamonds
Thanks to recent technological advances, lab-grown diamonds are now cheaper to manufacture and buy than mined diamonds. In addition, they are not only more affordable, but also have clear and documented environmental benefits.
While in the past the diamond industry has tried to convince us that mined diamonds are better than lab-grown ones, they are investing in lab diamond production themselves. To avoid hurting their existing brands and fat profits, they created separate lab-grown diamond brands, often aimed at younger, less affluent audiences.
So far, more and more jewelers have entered the lab grown diamond market, and consumers have gradually learned about lab grown diamonds from ignorance. Through the initial difficult attempt, we believe that lab grown diamonds will definitely shine in the jewelry market.
