Lab grown diamonds

As awareness of the SDGs has increased in recent years, Lab Grown Diamonds have been attracting attention as an ethical alternative to conventional natural diamonds.

A lab grown diamond is a synthetic diamond composed of the same components as a natural diamond. The composition, purity, and brilliance of a lab grown diamond are exactly the same as those of a natural diamond, and even professional appraisers are unable to identify them.

The GIA (Gemological Institute of America) and other diamond grading organizations can issue an official certificate of authenticity.

Because they are produced in a laboratory (factory), they do not create environmental and social problems like natural diamonds, and can be supplied ethically and sustainably. It has been attracting attention overseas, with celebrities such as DiCaprio, Penelope Cruz, Meghan Markle, Lady Gaga, and Emma Watson expressing their support. The price of the stone is 30-40% cheaper than the natural one, despite the fact that it has exactly the same ingredients and shine.

As the market demand for lab grown diamond jewelry continues to grow year after year, it is predicted that total sales will reach $15 billion by 2035.
