Diamonds, best known of the world’s gemstones, have fascinated potentates and collectors since their discovery near Golconda, India around 800 B.C. Austria’s Archduke Maximilian began a tradition in 1477 now considered integral to diamonds’ financial success. To symbolize his love for Mary of Burgundy, the duke was first to incorporate a diamond into a wedding ring. That use makes diamonds the most expected and purchased of all major gemstones. Seldom do accolades coincide with reality, but diamonds deserve all the superlatives showered on them. These gorgeous jewels, the crystal form of carbon, rate a 10 on the Mohs hardness scale of 1 to 10, as the hardest material in nature. Diamonds will scratch anything else, including other diamonds. And with an outstandingly high refractive index of 2.41, diamonds dazzle with rainbow hues. To a gemologist, a material must have three qualities to be classified as a gem: beauty, durability, and rarity. Clearly, diamonds qualify.

Formed between 70 and 400 miles beneath the earth’s surface, diamonds arrive where they can be found by humans by a unique delivery system. They must be forced through the earth’s crust within a volcano. The diamonds we are finding today were actually formed 900 million to 3 1/2 billion years ago. Diamonds forming beneath our feet today will remain unseen for billions of years.

India was the diamond source for most of our history with gems. The most famous diamond, the Hope, is a great 45.52-carat blue from India now on display at the Smithsonian Institution in Washington, DC. It now belongs to the American people. Diamonds occur in all colors, red being the rarest and most expensive.

Diamonds have the most organized gem trade, due to tight control once weighed by De Beers, the British and South African company that markets the majority of the world’s uncut diamonds. As explained in our new diamond book, diamonds are mined in a number of countries, with Australia, Botswana, and Russia producing most. South Africa remains important, as are Namibia, Angola, and Canada. Diamond cutting is concentrated due to De Beers’ tight distribution system of uncut (or “rough”) stones. India cuts more diamonds than any other country, mostly smaller sizes. Other major cutting centers are in Israel, Belgium, and the U.S. Increasing in importance are China, Thailand, and Russia. As a result of the “Diamonds Are Forever” campaign, romantics and investors buy almost all the gem-quality diamonds found annually. Most of the more than 100 million carats of diamonds mined each year are industrial-quality, required in prodigious amounts by modern societies to cut, grind, and polish almost every product we use: metals, optics, glass, molds, stone, ceramics, drill bits, dental drills, and millions more.

Diamond jewelry remains the dominant gem product sold in the USA and Europe. As explained in the Wards’ book, for most of the history of diamond use, the gems were reserved for royalty, celebrities such as Elizabeth Taylor, and other very wealthy patrons. But the phenomenal South African discoveries in the late 1800s produced so many diamonds suddenly that suppliers needed a new marketing plan. De Beers consolidated control and developed a broad buyer base. The twentieth century’s marketing revolution made diamonds (and other fine gems) available to everyone. For the first time in history, anyone with a job could afford a gem. And from the beginning of this change, the gems most people wanted were diamonds. The twenty-first century has ushered in the use of lab-created diamonds for extraordinary technical applications and gorgeous affordable jewelry.

I'm a gem dealer and jeweler, and am in love with Fred Ward's books. He touches on things rarely covered in drier professional tomes: history, romance, locales, and so forth. I've learned quite a bit I didn't know, not about the physical properties and grading of diamonds but about their mining and history, as well as industrial usage.

One thing that many people are becoming erroneously convinced of these days is that gem diamonds are common and intrinsically worthless; I love this book for clearly debunking that. Gem quality (as opposed to industrial) diamonds are rare, prized for valid reasons, and cost a great deal to mine and market. I think anyone reading this will get a realistic idea of why diamonds are priced as they are.

Wonderful photos and clear, well-written, well-researched text.
