WHAT:    ​​World’s Largest, First-Ever, Laboratory-Cultivated Pure Grown Diamond Unveiled

Just in Time for Valentine’s Day


SUMMARY:       During the Valentine’s Day engagement season, when diamond prices are skyrocketing, Pure Grown Diamonds announces a scientific breakthrough with the unveiling of the first-everworld’s largest, laboratory-cultivated white diamonds that are indistinguishable from mined diamonds, even under a microscope, yet cost 30 to 40 percent less, according to the International Gemological Institute.


The beginnings of the science to grow diamonds in the laboratory started in the late 1990’s in Sarasota. The 21st technological advancement has just now, been virtually perfected.


The world’s largest Pure Grown Diamond is 3.04 carats. It sells for $20,012 compared to an identical earth-mined diamond that sells for $40,000.

TAMPA – – During the Valentine’s Day engagement season, when diamond prices are skyrocketing, Pure Grown Diamonds announces a scientific breakthrough with the unveiling of the first-everworld’s largest, laboratory-cultivated white diamonds that are indistinguishable from mined diamonds, even under a microscope, yet cost 30 to 40 percent less, according to the International Gemological Institute.


Fiancés Suffer Sticker Shock


“This 21st Century technological achievement comes just before Valentine’s Day when an estimated six million American couples get engaged; when most men spend 25 percent of their annual salaries on diamond rings and when rough diamond prices are up 75 percent since 2009,” explains Pure Grown Diamonds President and CEO Lisa Bissell. “Most guys shopping for Valentine’s Day diamond engagement rings, bracelets, earrings, and necklaces are suffering sticker shock.”


Pure Grown Diamonds Rival Earth-Mined Diamonds in Every Respect


”During the past 70 years, many have tried but failed to grow scintillating, sizeable, colorless diamonds in the laboratory – until now,” explains Chief Technical Officer Dr. Devi Shanker Misra, PhD. He is a world-renowned physicist and inventor of the patented Pure Grown Diamond process. “No one, no company has achieved what Pure Grown Diamonds has accomplished — culturing thousands of alluring diamonds that rival mined-diamonds, in every aspect.”


Federal Trade Commission & Gemological Institute of America


According to the Federal Trade Commission, lab-grown diamonds have the same chemical, physical, and visual properties as mined diamonds.


When inspecting the world’s largest Pure Grown Diamond, which is 3.04 carats, the Gemological Institute of America remarked, “It’s impressive.”


Pure Grown Diamonds are cultivated from a carbon seed in a microwave plasma chemical vapor deposition chamber. The process replicates the earth’s process of crystalizing carbon into a diamond. Pure Grown Diamonds mature within six to 10 weeks.


Diamonds Are A Girl’s Best Friend But Huge Expense to Mother Nature


“Pure Grown Diamonds are the reasonably-priced, eco-friendly, conflict-free preference of shoppers seeking value; for consumers concerned about the environmental impact of mining; for people troubled by the history of human rights violations and greed-motivated violence in mining regions of developing countries,” says Bissell, a seasoned diamond business executive – among the few women CEO’s in her industry.


World’s Largest Pure Grown Diamond


The world’s largest laboratory Pure Grown Diamond was cultivated in November 2014. 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


An earth=mined diamond of near identical characteristics sells for approximately $40,000 at some of the best-known jewelry retailers in America.


One carat round diamonds are the most popular for engagement rings in the U.S.


Pure Grown Diamonds quality one carat stones are priced from $1,000 to $3,000.


A one carat earth-mined diamond starts at $5,000 and can cost more than $10,000.


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 the Valentine’s Day 2015 global launch of its e-commerce website:


Many of the company’s jewelry pieces are priced as low as $300.


The Inventor & His Invention: The Pure Grown Diamond Process


“Pure Grown Diamonds is about to change the landscape of the mining and jewelry industries,” says Misra.


“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.


The earth’s process of crystalizing carbon is exactingly replicated in state-of-the-art, high-tech facilities.


The diamond seed is placed inside the 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, depending on the size of the diamond.


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


Not Artificial


“Pure Grown Diamonds are not artificial; not synthetic; not cubic zirconium; not costume jewelry. They are diamonds,” emphasizes Bissell.


The only difference between a mined diamond and a Pure Grown Diamond is that one is grown in a lab and the other is grown under the earth’s crust, according to Misra.




The difference between earth-mined diamonds and Pure Grown Diamonds are detectible only by highly sophisticated spectroscopic equipment and from Pure Grown Diamonds’ laser-scribed identifications on the stones’ girdles that read, “Laboratory Grown.”


This is a voluntary policy of transparency that clearly identifies the source of the diamond.


IIa Technologies


Pure Grown Diamonds is the exclusive North American retailer and distributor of diamonds grown by IIa Technologies.


Pure Grown Diamonds are cultivated at IIa (2a) Technologies in Singapore, which is Pure Grown Diamonds sister company.


The company is named after the purest and rarest diamonds – Type IIa, which comprise less than 2 percent of all mined diamonds.


Pure Grown Diamonds are Type IIa diamonds, which have a unique growth structure and remarkable clarity and brilliance.


Few mined diamonds are Type IIa. They are very rare.


Britain’s Queen Elizabeth and celebrity Elizabeth Taylor are the few women in the world that have worn and owned Type IIa diamonds.


CEO Vishal Mehta characterizes IIa Technologies as, “A one-of-a-kind, cutting-edge company, which, after years of research and development, finally achieved a revolutionary breakthrough – cultivating actual, near colorless diamonds of significant carat size.”


He continues, “The company’s mission is to further enhance the cultivation of high-quality, sizeable diamonds with the end-goals of marketability and commercial viability and to strive for perfecting processes for a diverse set of diamond applications.”
