When we talk about jewelry, usually the first thing that pops up in your mind is diamond. For my friends, who are not in the industry, they often give me perplexed looks when I mention other types of jewelry that are out there. On the contrary, when I talk about diamond, they all know what it is. Everybody knows that diamond is expensive and has high market value. But only a handful of people knows where does diamond come from, what are its properties, and why is it so expensive?
Diamond is derived from the Greek word, adámas, which means unbreakable. Some of you may wonder, what does it mean by unbreakable? Actually, the word 'unbreakable' may be somewhat misleading because I believe some of you have broken or nicked the diamond in the past. However, the ancients call diamond 'the unbreakable' because of its hardness. On the Moh's scale from 1 to 10, diamond is the only kind of gemstones that has a hardness of 10, where hardness is defined as resistance to scratching. In other words, diamond is the hardest one. Therefore, it is highly unlikely to find a scratch on diamond. You can try scratching the diamond with other gemstones, you will not find any scratch on the diamond, just like the phrase "diamond cuts diamond", which, literally means nothing cuts a diamond but a diamond. At this point, I think you can see why diamond is expensive.
To spice things up a little bit, let's talk about the formation of diamond. It is formed in the mantle, which is somewhere 2,500 km below the Earth's surface. Diamond is beared in a type of rock called Kimberlite, which is carried closer to us by volcanic eruptions. When there is an eruption, magma elevates kimberlite with diamond inside to the surface, and there we have it, diamond!! For this very reason, I think now you understand why diamonds are found somewhere close to the volcanoes.
