Type IIB Diamonds

Also known as blue diamonds, Type IIB diamond are extraordinarily rare. Studies show that just almost a hundredth of a percent of mined diamonds fall under this category. Type IIB diamonds are highly valuable as well and this makes it challenging to study. Scientists have been trying to know all the most expensive diamonds in the world.

The Hope diamond and the Cullinan Dream are two of them. The Hope diamond is known to be cursed and it has changed owners through the years. The Cullinan Dream is a 24.18 carat that sold for at least 23 Million USD at an auction back in 2016.

Scientists analyzed the inclusions and the remaining minerals in the diamonds so that they can estimate what the diamonds contain and where the stones were formed. They determined that the inclusions they found in their diamonds showed that the stones were formed in the lower mantle, 410 to 660 kilometers or 250 to 410 miles underneath the surface of the Earth. They concluded that blue diamonds are not only the deepest and rarest expensive diamonds on the planet.

Discovering blue diamonds in the earth’s mantle shows that the Earth reuses its surface minerals in deeper parts of the mantle. Their amazing blue color is from the element called boron, which is almost just found on the surface of the earth. Boron is usually present in mineral deposits underwater.

Why There are Highly Expensive Diamonds

The natural color of a diamond is the tint of color the stone has as it develops. While there are clear or white diamonds, there are a few, rare fancy diamonds that interact with various materials and gases. Because of this, the diamonds develop different shades of blue and pink. These are the rare expensive diamonds, as well as those that are darker red and pink.

The diamond’s facet number and cut also influence its price. There are specific cuts that are smaller, which result in a rougher diamond that retains much of its value. Once the diamond gains extra facets to conceal or eliminate inclusions, its value goes down.

Clarity is also a consideration. Gemstone cutters and jewelers have a system with which they can gauge the imperfections of any diamond. If they find more inclusions in the stone, the diamond’s value lowers.
