The History of Lab Grown Diamonds – Modern Times
14 june 2017
(ehudlaniado.com) - Recently, we looked at the history of synthetic diamond manufacturing, and saw how it began in the late 1800s. While the machines for growing diamonds have improved tremendously over the past few decades, the methodology of today is not very different than it was in the 1950s, when GE pioneered the mass production of industrial-quality synthetic diamond. For the moment, there are two primary methods of manufacturing diamonds that most in the industry are familiar with. But there are, however, other processes that for the moment are cost prohibitive and do not possess the ability to mass-produce diamonds of any quality. But as technology improves, and as other technologies built for other industries become applicable to the manufacturing of diamonds, we may still see further developments. Let’s take a closer look at how diamonds are being synthesized in laboratories today.
US: A Great Past, But Will it Hold the Future of Diamonds?
13 june 2017
(ehudlaniado.com) - The US consumer market is the key market for the diamond industry, responsible for about 40% of global demand by value. However, although the US is the leading market, it is a very stable one, for better or for worse. While stability in a business is valuable, it is difficult to generate a drive for growth in a stable environment.
Slower Visitor Traffic at JCK
09 june 2017
(diamonds.net) - There was a bit of a debate raging among exhibitors at the JCK Las Vegas show, and part of it revolved around the organizers’ decision not to hold the event over a weekend. Buyer traffic was down — according to some estimates, by 20% to 25% — and suppliers were trying to figure out why. The popular theory was that retailers didn’t want to leave their stores during the week and therefore decided to give JCK a miss this year. But as one established buyer argued, “the weekend is a store’s busiest selling time. So if anything, it’s better for them to hop over to Vegas during the week.” Rather, he suggested, the show didn’t have the “junket” retailer who comes for the weekend party, attends the show for an hour or two, and spends the rest of the day at the pool. This year’s show had fewer, but more serious buyers roaming the aisles. And they came with very specific requirements that were not easy to fill, explained one New York-based manufacturer, who requested anonymity.
The History of Lab Grown Diamonds
09 june 2017
(ehudlaniado.com) - Synthetic, lab-grown, artisan-created, man-made, or cultured. Whatever you choose to call them, lab-grown diamonds are highly controversial these days, and the diamond media reports regularly on new developments in this growing industry. Whether you like it or not, lab-grown diamonds are not going away, and the technology used to grow them is improving rapidly. As with any product or service, when there is demand for something, companies will continue to enter the marketplace to provide the supply to meet that demand. The demand for lab-grown diamonds is growing in some of the major diamond-consuming nations, but not in others. In my next series of articles, I will take an in-depth look at the burgeoning phenomenon of lab-grown diamonds. I’ll examine their history, how they are made, and their applications. I’ll also discuss how the natural diamond market is reacting to them, how the supply/demand fundamentals are shaping up, and how they are currently being priced in the market.
Diamonds, Including Man-Made, the Focus at Borsheims
08 june 2017
(nationaljeweler.com) - There was ping-pong and bridge with Bill Gates, shiny stones with the Oracle of Omaha’s signature on the girdle and lab-grown diamonds. The man-made stones were among the offerings jeweler Borsheims had during parent company Berkshire Hathaway’s annual shareholder weekend, which took place in early May in Omaha. The retailer has been very quietly carrying man-made diamonds since November, mixing in fashion pieces from Swarovski, which started selling jewelry set with lab-grown diamonds in 2016, with bridal rings from a company called Altr.
