Diamonds form alongside a distinct purple companion. We studied it to reach a conclusion about how rare they might actually be.
Our research marks the first case of both normal diamonds, as well as Londaleite, being produced in a lab setting using only intense pressure.
Whether forged by geological processes or laboratory techniques, diamonds are diamonds. Their unique properties mean they have applications that are not bling-related as well.
Some diamonds come from depths of more than 650km. Tiny imperfections in these gems give us clues about what’s happening in Earth’s hidden geological layers.
Zirconia is a mineral with a crystal structure made from the elements zirconium and oxygen. It looks pretty like diamond, but is only worth a fraction of the value.
What makes a stone a gem? It boils down to a few key qualities: beauty and durability. But opal, the national gemstone of Australia, is an anomaly - it’s soft.
The world’s biggest diamond company is to sell synthetic gemstones for the first time.
With current modes up against their limits, we need new data storage solutions. Tiny defects in diamonds’ atomic structure might turn them into a new medium for memory.
Zimbabwe has said it will take over all diamond mining operations in the country. But what is needed to maximise revenues isn’t state ownership, but improvements in existing regulatory practices.
Shopping for a gold ring? New guidelines seek to be the rough equivalent of Fair Trade for small-scale gold mining.
From the outside, Number 2 Hoveniersstraat Street in Antwerp is a nondescript office block. Only the clusters of businessmen speaking in Gujarati on their mobile phones or with each other, give any indication…
A new discover in the field of quantum electronics could lead to a dramatic improvement of computing speeds, data storage…
Kimberlite, a volcanic rock which is best known as a major host of diamonds, has been discovered for the first time in Antarctica…
Diamond is well known for its appeal as a gemstone. Perhaps less well known are some of its extreme material properties. As well as being the hardest material in nature, diamond is very good at conducting…
Diamonds from 700 kilometres below the earth’s surface show the carbon cycle extends deep into the planet’s interior. The…
