6 Facts must check before buying Lab Grown Diamonds
Lab Grown diamonds
It’s identical to a natural one and doesn’t have to be mined
A clear, glittering diamond is rare. That’s part of its demand. That mined today formed billions of years ago. But a new method can create gem-quality diamonds on appeal in just three months.
They’re most similar to their natural counterparts and cost 30 to 40 percent less. That’s promising for anyone in the market for an engagement ring. And it bodes well for the future of electronics too.
On increasing demand, the use of it in modern days jewelry is getting high too.
So if you are thinking to buy one, here are the 6 Facts that you must know about Lab Created Diamonds before buying it
1. Global demand for diamonds is recently on the hike, thanks in part to an increasing middle class in countries such as India and China. But it’s been 10 years since a large diamond mine has been found.
By 2019, demand is projected to outstrip supply by 5 to 6 percent.
2. Luckily, diamonds can also be grown in a lab. In the 1950s, scientists first created diamonds by replicating the intense heat and pressure that results in the creation of them underground.
The stones tend to be small and discolored (in some cases just a powder), but they retain a natural diamond’s defining properties.
3. Natural Diamond is one of the hardest known materials. It can withstand high levels of radiation and doesn’t trigger an immune response. This makes it useful in medicine, nuclear engineering, and construction.
In 2013, industry used about 1,500 tons of diamond, 99 percent of them were lab-grown.
4. To make purer gems, diamond-grower IIa Technologies refined a process called chemical vapor deposition. In a vacuum chamber, they shower a fingernail-thin diamond “seed” with microwave rays and hydrogen and methane gasses. These build up layers of carbon bonds.
5. In March, IIa opened the world’s largest diamond-growing facility in Singapore. It’s capable of cranking out more than 300,000 Carats a year, using half the energy of diamond mining. Plus it has a far less environmental impact.
To the naked eye, the diamonds are indistinguishable from natural ones. But they’ll still be a tough sell for jewelry, where lab-grown make up less than 1 percent of the market.
“They’re seen as inauthentic, no matter that they are objectively identical,” explains Ravi Dhar, director of the Center for Customer Insights at Yale University.
6. Diamond’s unsurpassed thermal conductivity makes it an ideal heat sink for electronics. It transfers about twice the heat and can carry more current than the silicon usually used in semiconductors.
IIa is working to grow diamond plates that will enable smaller, more-powerful devices that don’t overheat. “It will take time,” says physicist Devi Shanker Misra, who invented IIa’s technique, “but I hope that it will replace silicon.”
