Diamonds have been the hardest naturally occurring substance on Earth for decades. An allotrope of carbon, the carbon atoms are arranged in a structure commonly defined as a lattice and have extremely strong covalent bonds that give it great physical features like the highest thermal conductivity and hardness. According to history books diamonds were first mined for in India all the way back in the 4th century. It was here they first started to be used as gem stones. The uses of diamonds increased from the 19th century onwards, due to a range of factors like better polishing machinery and techniques, easier access to diamond mines situated around the world, and the general growth in the world’s wealth and economy.
Nowadays diamonds are popular as jewelry and industrial cutting equipment. They are extremely sought after for jewelry because of the dazzling and eye catching way they disperse of light. The prices vary depending on the carat, size and color. Since diamonds are the hardest naturally occurring substance, there are used for drill bits, saw blades and such equipment, because diamonds can cut basically anything. The resistance to wear also makes it ideal for usage as bearings in mechanical devices and they are also used in x ray machines because of their excellent resistance towards heat and abrasion. A new trend that is getting popular day by day is turning cremation ashes diamond in Hong Kong. They allow you to hold a true memorial and memory of someone close to you.
It is one of the most unique and bizarre cremation jewelry currently available. It works by taking the cremation ashes diamond cost and placing it in a crucible. This crucible is heated to up to 5000 Fahrenheit’s so that everything except the carbon oxidizes. The heating is then continued for days, and sometimes even weeks until the carbon turns into graphite. The core is placed into a diamond press after that and exposed to extreme temperatures and pressures almost up to 800,000 pounds per square inch. The end result of this is that the graphite morphs into a rough and irregular crystal. Cutting tools can then be used to cut and polish it to your taste.

The main issues with diamonds are the conflict diamonds or commonly known as blood diamonds. In unstable African countries, it is not unusual for rebel and terrorist organizations to take over diamond mines and use the money to fund their military or terrorist activities. There have been scandals and exposures where major diamond dealing companies fuel these activities by directly dealing with the military organizations.
