World’s Largest Laboratory-Made Diamond
The diamond pictured above is a whopping 3.04 carats. Its price tag may shock you, not because it’s so expensive but because it’s surprisingly less expensive.
That’s because it’s the world’s largest laboratory-cultivated diamond, revealed for the first time by Lisa Bissell, president and CEO of Pure Grown Diamonds, yesterday at Pure Grown Diamonds Subterranean Diamond Vault Showroom in New York.
Thanks to scientific and technological advancements, the diamond (near colorless 3.04 carat, round stone, I color, SI1 clarity, excellent cut) is indistinguishable from mined diamonds, even under a microscope, according to the International Gemological Institute, who certified the gemstone.
The U.S. Federal Trade Commission said that Pure Grown Diamonds are composed of the exact same chemical, physical and optical properties as mined diamonds.
“Pure Grown Diamonds are not artificial; not synthetic; not cubic zirconium; not costume jewelry. They are diamonds,” Bissell said in a press release.
In fact, the difference between a diamond from the earth’s crust and one grown in a lab can only be detected by highly sophisticated spectroscopic equipment — and from Pure Grown Diamonds’ laser-inscribed print that reads, “Laboratory Grown” on the stones’ girdles.
Lab-made diamonds cost 30 to 40 percent less; an identical earth-mined diamond is priced at approximately $40,000 at jewelry retailers nationwide, compared to $23,012 for the lab-grown version which, by the way, is available for purchase at PureGrownDiamonds.com.
How Diamonds are Grown in a Lab
- Lab Cultivated Patented Process: Microwave Plasma Chemical Vapor Deposition
- Diamond seed placed in chamber
- Methane & hydrogen gases introduced
- Microwave energy pumped in
- Plasma ball ignites
- Carbon molecules rain on seed
- Crystallization occurs in 6-10 weeks
- The diamond is cut with a laser, polished and then certified by the International Gemological Institute
