Here, a diamond seed is placed in a vacuum chamber, and carbon atoms from a carbon-rich gas, typically methane, are ionized and deposited onto it. As these carbon atoms accumulate, they crystallize, forming dia
What is a natural diamond? A diamond is an amazing miracle of nature made up of billions of carbon atoms. Diamonds have a unique cubic crystal lattice structure. Each carbon atom in a diamond is strongly bonded to four others, making them the hardest known natural substance. Diamonds also ex...
The 2024 Formula 1 season wraps up this weekend in Abu Dhabi and in many ways nothing is different, but at the same time, everything has changed. First off, you have Max Verstappen. The Dutch driver wrapped up his fourth straight title a couple weeks ago. But his team, Red Bull, has...
In this article, we will track a diamond from the time it is formed to when it reaches the Earth's surface. We will also examine the artificial rarity created by the diamond cartel, De Beers, and briefly discuss the properties of these gems. First, we'll discuss carbon, the element beh...
Instead it is thought to be present primarily in the mantle beneath the stable interiors of continental plates [2]. Diamonds formed and stored in these "diamond stability zones" are delivered to Earth's surface during deep-source volcanic eruptions. These eruptions tear out pieces of the mantle...
In Kuala Lumpur, "melting pot" is more than a cliché; it’s at the heart of the city’s emergence.
Carl Walsh, right, QUT Ph.D. researcher and lead author of a paper published inNaturewith QUT Professor Balz Kamber. Carl is looking at a cube of garnet peridotite. The color of this garnet shows the presence of chromium, which is an indicator of the presence of ...
A deeply cut stone will affect the way light reflects in the mass of the diamond. A very shallow cut stone will seem dark because the light exits the back of the stone and the angles do not reflect the light back up through the top of the stone to your eye. Clarity, which is ...
The sun is composed of gas. It has no solid surface. However, it still has a defined structure. The three major structural areas of the sun are shown in the upper half of Figure 1. They include: Core: The center of the sun, comprising 25 percent of its radius. Radiative zone: The ...
versions. Not every lab-grown diamond will feature all these markers, and it is therefore a case of trying to identify as many of them as possible to ascertain whether a diamond is lab-grown or natural, and, in the case of the former, to pinpoint the specific type of synthetic diamond...
