Lab grown diamonds have grown in popularity as many retailers have experienced in 2022. Some retailers tend to sell only natural, mined diamonds while others see the growth of the lab market as a means to enable them to cater to customers with a variety of budgets. Many end consumers have a certain size diamond they would like to purchase and lab created diamonds enable them to afford this desire.
GN Diamond has reported a tremendous growth in finished jewelry featuring lab created diamonds, especially with classic diamond studs and tennis bracelets. In 2022, GN also reported a steady market for natural diamonds, especially for engagement and bridal sales. Natural diamonds of all sizes were sold over the holiday season in a variety of shapes – not only rounds and ovals, but also marquise, emerald and radiant cuts.
“No matter what the retailer’s preference, there is plenty of business for the coexistence of both natural and lab grown diamonds,” says Asaf Herskovitz, CEO of GN Diamond. “Both types have many advantages.”
Some of the benefits of purchasing lab grown diamonds include they are made in America and are being certed by GIA and IGI. This has created an even greater demand.
Lab Made Diamonds – Two Popular Methods
There are two processes used to create lab grown diamonds:
1. Chemical Vapor Deposition Diamonds
The first process is called Chemical Vapor Deposition (CVD). A seed crystal, which is a very small diamond seed, is placed in a small chamber. The chamber is then filled with gases that are heated. Once the gases reach the right temperature, layers of carbon begin to form on the seed crystal. This causes the seed to grow and create a square-shaped diamond crystal.
2. High Pressure High Temperature Diamonds
The second process is called High Pressure High Temperature (HPHT). This is meant to replicate the earth’s process of forming natural diamonds. In this process, natural graphite is placed in a large machine that crushes it with extreme pressure and temperatures. Under these conditions, the graphite turns into a diamond.
What is the Difference Between CVD and HPHT Diamonds?
You cannot tell the difference between a CVD and HPHT diamonds with the naked eye. Both methods create a real diamond with the same physical and chemical properties as natural diamonds. When it comes to grading lab grown diamonds, the same 4 Cs: Color, Cut, Clarity and Carat are applied. Lab grown diamonds have the exact same durability and hardness level. Both come with diamond certifications. They are so visually alike that the differences cannot be seen to the naked eye.
“With over 7,000 lab created diamonds and over 9,000 natural diamonds, GN will certainly help you create more sales,” says Herskovitz. “We offer free overnight shipping as well.”
