Earth grown diamonds are mined from deep under the earth's surface where they have lain dormant for millions of years. When you hold an earth grown diamond, reflect on the immense journey this diamond has taken and the history it has endured.

Then miners dig deep tunnels under the earth and collect the rough diamonds. The rough diamond looks nothing like the sparkly diamond you are holding. It has an irregular shape, is very dirty and looks dull. The diamond is then cleaned, cut into its desired shape, and finally polished into the beautiful diamond you are now holding!

Although much more common in the past, conflict diamonds are now very hard to obtain in most countries thanks to the Kimberley process. The Kimberley process was established in 2003 by the United Nations to ensure that all diamonds are ethically sourced and are not used to finance wars.

At Ritani, we go above and beyond that to make sure that all our diamonds are ethically sourced and come from companies that treat their workers fairly. We carefully select our suppliers and ensure that the diamond you get was mined ethically and conflict free.

By the late twentieth century, the earth was no longer the only source for diamonds. In 1970, General Electric began creating diamonds in a laboratory and the first gem-quality laboratory-grown diamond were sold in 1984. With advances in technology, man-made diamonds have become more common and harder to detect. Learn more about laboratory-grown diamonds.

But a closer look shows that it's not that millennials have altogether stopped buying diamonds. They spent $26 billion on the stones in 2015 alone, more than any other single generation, according to the De Beers Annual Diamond Insight Report. Millennials are approaching both money and marriage differently, though, and it's affecting their spending habits.

While for a while, diamonds were often de rigueur, more and more of today's young couples are opting for other stones, such as sapphires or rubies, to signify commitment. Those can stand out more as unique and can also serve as a way for consumers to rebel against what they see as the diamond industry's heavy-handed marketing tactics.

Diamond ore can be mined using an iron pickaxe or stronger. An ore drops a single diamond. If mined by any other tool, it drops nothing. If the pickaxe is enchanted with Fortune, it can drop an extra diamond per level of Fortune, allowing for a maximum of 4 diamonds with Fortune III. If the ore is mined using a pickaxe enchanted with Silk Touch, it drops an ore block rather than a diamond. The ore is found at level 15 or lower, most commonly between -50 and -64; levels -58 and -59 are the preferred levels to mine at since they don't contain bedrock, as it starts spawning at -60.

Diamonds have long been a staple for engagement rings, wedding anniversary gifts and even the tips of drills. It was diamonds that brought fame and fortune to luxury brands like Tiffany & Co. and Harry Winston.

Hope Rehak is a 26-year-old graduate student at Northwestern University. Growing up, diamonds were never looked at as a sign of luxury or necessity in her family. Her mother had a wedding band without diamonds, and she recalls her progressive parents telling her that a lot of diamonds were unethical.

Rehak only recently started paying attention to the diamond industry at all, and that was because as a young millennial woman in her mid 20s, a lot of her friends around her began getting engaged. While Rehak is living the single life, she said that even when she falls in love and gets engaged she has no expectation of diamonds.

Small numbers of diamonds began appearing in European regalia and jewelry in the 13th century, set as accent points among pearls in wrought gold. By the 16th century the diamonds became larger and more prominent, in response to the development of diamond faceting, which enhances their brilliance and fire. Diamonds came to dominate small jewels during the 17th century and large ones by the 18th century.

In the 13th Century, Louis IX of France established a law reserving diamonds for the king. This bespeaks the rarity of diamonds and the value conferred on them at that time. Within 100 years diamonds appeared in royal jewelry of both men and women, then among the greater European aristocracy, with the wealthy merchant class showing the occasional diamond by the 17th century.

As more diamonds reached Europe, demand for them increased. The earliest diamond-cutting industry is believed to have been in Venice, a trade capital, starting sometime after 1330. Diamond cutting may have arrived in Paris by the late 14th century. By the late 14th century, the diamond trade route went to Bruges and Paris, and later to Antwerp.

By 1499, the Portuguese navigator Vasco da Gama discovered the sea route to the Orient around the Cape of Good Hope, providing Europeans an end-run around the Arabic impediment to the trade of diamonds coming from India.

In the 18th century the diamond became even more abundant. They were worn principally by women. Substantial quantities of diamonds arrived from South America, making conspicuous display of the gem possible. Diamonds were reserved for evening since it was considered vulgar to parade them by day. Rather than a miscellany of jewels of different types, a matched set of jewelry -- was now worn at all important social events.

Two events near the end of the 19th century helped change the role of diamonds for the next century. First, the discovery in the 1870s of diamond deposits of unprecedented richness in South Africa changed diamond from a rare gem to one potentially available to anyone who could afford it. Second, the French crown jewels, sold in 1887, were consumed by newly wealthy capitalists, particularly in the United States, where a taste and capacity for opulent consumption was burgeoning.

Before the 1870s diamonds were still rare, and associated with the aristocracy. In 1871, however, world annual production, derived primarily from South Africa, exceeded 1 million carats for the first time. From then on, diamonds would be produced at a prodigious rate.

Today diamonds are mined in about 25 countries, on every continent but Europe and Antarctica. However, only a few diamond deposits were known until the 20th century, when scientific understanding and technology extended diamond exploration and mining around the globe. For 1,000 years, starting in roughly the 4th century BC, India was the only source of diamonds.

It is a modern misconception that the world's diamonds come primarily from South Africa: diamonds are a worldwide resource. The common characteristic of primary diamond deposits is the ancient terrain that hosts the kimberlite and lamproite pipes that bring diamonds to Earth's surface.

Diamonds are formed deep within the Earth about 100 miles or so below the surface in the upper mantle. Obviously in that part of the Earth it's very hot. There's a lot of pressure, the weight of the overlying rock bearing down, so that combination of high temperature and high pressure is what's necessary to grow diamond crystals in the Earth. As far as we know, all diamonds that formed in the Earth formed under those kinds of conditions and, of course, that's a part of the Earth we can't directly sample. We don't have any way of drilling to that depth or any other way of traveling down to the upper mantle of the Earth.

The diamonds that we see at the surface are ones then that are brought to the surface by a very deep-seated volcanic eruption. It's a very special kind of eruption, thought to be quite violent, that occurred a long time ago in the Earth's history. We haven't seen such eruptions in recent times. They were probably at a time when the earth was hotter, and that's probably why those eruptions were more deeply rooted. These eruptions then carried the already-formed diamonds from the upper mantle to the surface of the Earth. When the eruption reached the surface it built up a mound of volcanic material that eventually cooled, and the diamonds are contained within that. These are the so-called Kimberlites that are typically the sources of many of the world's mined diamonds.

We can grow diamonds in the lab and we can simulate conditions there. But there are things we have to do to grow diamonds in the laboratory that aren't obvious as to how it happens in the Earth. In the laboratory, they're typically grown, but there's some catalyst. Some metals are often added to cause the diamonds to grow, but these same catalysts are not observed in the diamonds from the upper mantle of the Earth.

The Hope diamond is at least a billion years old. You don't see the original rock that carried the diamonds to the surface, but they have found some Kimberlites in India that do have evidence of diamonds in them. Those Kimberlites date to at least a billion years old. So that suggests the Hope diamond and similar diamonds found in India were brought to the surface at least a billion years ago and perhaps longer ago. So we're comfortable saying that the Hope Diamond is at least a billion years old. When you look at the age spread of most other diamonds, it's probably much older that that. 006ab0faaa
