Pure Grown Diamonds announces scientific breakthrough with unveiling of world's largest laboratory-cultivated pure white diamond, indistinguishable from mined diamond, even under microscope, yet costs 30 to 40 percent less -- just in time for holidays. First-ever, largest lab-grown diamond is 3.04 carats shown here in comparison to 1.0 carat stone at showroom on Manhattan's Jewelry Row.

The first-ever, largest lab-grown diamond is 3.04 carats.

Pure Grown Diamonds have the exact same chemical composition, physical properties and optical features as earth-mined diamonds, according to the International Gemological Institute.

Pure Grown Diamonds mature within six to 10 weeks. They are eco-friendly and "conflict free," unlike mined diamonds.

Holiday Diamond Shopping Sticker Shock Due to Shrinking Natural Resources

"This 21st Century technological achievement comes during the holiday season when 26 percent of all American couples get engaged; when most men spend 25 percent of their annual salaries on a diamond ring and when rough diamond prices are at an all-time high," explains Pure Grown Diamonds President and Chief Executive Officer Lisa Bissell. She is one of the few women CEOs in the diamond industry.

She continues, "Most guys shopping for diamonds in December will suffer sticker shock because rough diamond prices are up 75 percent from five years ago, due to depletion of natural resources and increased global consumer demand."

Bissell adds, "Many have tried and failed; no one, no company has achieved what Pure Grown Diamonds has accomplished -- culturing thousands of alluring diamonds, including the largest, which is more than three carats."

World's Largest Pure Grown Diamond

The world's largest laboratory Pure Grown Diamond was cultivated in late November. It is certified by the International Gemological Institute. It is a near colorless 3.04 carat, round stone, I color, SI1 clarity, very good cut. It sells for $23,012 on

Mined diamonds of near identical characteristics sell from between $38,000 and $46,000 on some of the best-known jewelry websites in America.

Pure Grown Diamonds quality one carat stones are priced from $1,000 to $4,000. A one carat mined diamond starts at $5,000. One carat round diamonds are the most popular for engagement rings in the U.S. Starting price for diamond jewelry is about $300.

Most Pure Grown Diamonds are E-H color and VVS1-VS2 clarity certified. The highest colorless rating is D. The highest clarity rating is VVS1.

The company has been quietly growing and harvesting thousands of white, yellow and pink diamonds and making earrings, bracelets, necklaces and rings for this month's launch of its global e-commerce website:

Diamonds Are a Girl's Best Friend But at Huge Expense to Mother Nature

"Pure Grown Diamonds is the new affordable option for shoppers seeking value; for consumers concerned about the environmental impact of mining; for people troubled with the history of human rights violations in the mining industry and the deadly armed conflicts ignited by greed," says Bissell.

She emphasizes that incidents of violence and violations have tapered-off in recent years because of global news coverage that exposed these once commonplace incidents.

The Inventor

"Pure Grown Diamonds is about to change the landscape of the mining and jewelry industries," says Pure Grown Diamonds Chief Technical Officer Dr. Devi Shanker Misra, Ph.D.

"Mining dramatically alters eco-systems and wild habitats, unlike Pure Grown Diamonds, which are marvels of technology that do not undermine the sustainability of the environment."

Misra is a world-renowned physicist, former professor at the Indian Institute of Technology, Bombay, Mumbai, India. He is the inventor of the patented Pure Grown Diamond process that cultivates incredible diamonds in a Microwave Plasma Chemical Vapor Deposition chamber from a small carbon seed. It takes from one-and-a-half to two-and-a-half-months to grow a diamond.

"Consumers now have an intelligent choice that ultimately preserves human life and the planet's natural resources for future generations," says Misra.

Federal Trade Commission

"Pure Grown Diamonds are not artificial or synthetic and not cubic zirconium," emphasizes Bissell.

According to the United States Federal Trade Commission (FTC), the term 'synthetic' in reference to lab-grown diamonds, is misleading as it implies that such stones are imitations.

The only difference is that one is grown in a lab and the other is grown under the earth's crust, according to Misra.

Pure Grown Diamonds are Type IIa diamonds, which have a unique growth structure. Pure Grown Diamonds are detectible only by highly sophisticated equipment and from their laser-scribed identifications on the stones' girdles that read, "Lab Grown."

The Pure Grown Diamond Process

"Pure Grown Diamonds are cultivated at its Singapore sister company IIa Technologies' state-of-the-art facilities where the earth's process of crystalizing carbon is exactingly replicated.

A diamond seed is placed inside a low-pressure microwave chamber. Hydrogen and methane gases are introduced. A microwave generator pumps energy into the chamber that ignites a glowing plasma ball. Carbon molecules rain on the seed. Crystallization begins. The process is completed within 42 to 70 days.

The diamond is cut with a laser, polished and then certified.
