A report on the official British government website states that scientists at the Atomic Energy Authority and the University of Bristol are collaborating to develop a high-end technology for manufacturing diamond batteries.
Scientists say these batteries can power devices such as computer chips, smoke alarms, pacemakers or small satellites, and don't need to be recharged for decades or thousands of years.
Such batteries should be very small, powered by a small amount of graphite from previous nuclear reactors.

The report quoted Professor Scott as saying: "Bristol is working with Coolum to set up a spin-off company and start trial operation of these devices. We hope to produce 10,000 to 20,000 devices per year, but eventually hope to produce each Millions of devices.
"This is a very exciting project-our goal is to be the world leader in diamond batteries," he added.
The special physical properties of diamond make it have wide application prospects. They have surrounded us in the equipment we use in our daily lives-dentists use tools set with diamonds to treat cavities, diamonds for computers and high-end speakers. There are many more applications, and now they will be used as a powerful energy source. Here are some of the latest news in the field of diamonds compiled by Xiaobian this week.

2. Under the influence of the new crown virus, diamond performance has shown a slow decline
Under the influence of the new crown virus, diamond sales were once blocked. Although the price of diamonds did not show a significant downward trend, but in the long run, it is very slow to ensure that they are not affected.
Jewellery consumption reached a record low. During the Lunar New Year, China ’s total consumption of jewelry, cosmetics, etc. fell by 60% year-on-year. At the same time, the news that Hong Kong's jewellery and luxury goods consumption reached a record low in 2019 is also spreading, especially the consumption in December 2019, which actually fell by nearly 37% year-on-year.
Changes in the retail market have also affected the supply chain. According to the AWDC (Antwerp World Diamond Centre), Hong Kong and the United States are the largest exporters of finished diamonds in Belgium, each accounting for about 25% of the total export value. The ranking of diamond exports to Hong Kong in January has slipped to third place, with only 13% of exports. The export value of US $ 81 million in polished diamonds was nearly 40% lower than that of 132 million in the same period last year. In contrast, diamonds sent directly to mainland China fell by as much as 60% year-on-year (1.2%).

Improved synthetic diamond cultivation technology has provided the conditions for the emergence of the diamond "gray" market. Unscrupulous market players have begun replacing natural diamonds with synthetic diamonds. To protect consumers from gemstone fraud, ALROSA has developed and patented a special device.
The unique portable diamond authenticity detector is a true technological breakthrough with three optical analysis methods. This compact instrument is functionally superior to many benchtop and mobile detectors.
