"Diamonds are (forever) Carbon too. Certainly, you prefer diamonds instead of charcoals. But chemically speaking, diamonds and charcoals are just carbon in different form. Under certain temperature and pressure, the mother-nature took more than 1 billion years for transforming carbon-bearing materials into clear and shining diamonds. No wonder you prefer diamonds instead of regular charcoals."

"But remember, that manners must adorn knowledge, and smooth its way through the world. Like a great rough diamond, it may do very well in a closet, by way of curiosity, and also for its intrinsic value; but it will never be worn nor shine, if it is not polished."

"I have found that humanity is not incidentally engaged, but eternally and systematically engaged, in throwing gold into the gutter and diamonds into the sea."

"Unlike other carbons, a diamond uses all its bonding electrons to link with neighbouring atoms. These pair bonds are what give the gem unsurpassable hardness and fire."

"Diamond molecules refract light because they are shaped like pyramids. Try making a three point pyramid on your man."

"Wit must be foiled by wit: cut a diamond with a diamond."

"The soul is placed in the body like a rough diamond, and must be polished, or the luster of it will never appear."

"Why do people like these things? They're just shiny rocks."

"The diamond invention—the creation of the idea that diamonds are rare and valuable, and are essential signs of esteem—is a relatively recent development in the history of the diamond trade. Until the late nineteenth century, diamonds were found only in a few riverbeds in India and in the jungles of Brazil, and the entire world production of gem diamonds amounted to a few pounds a year. In 1870, however, huge diamond mines were discovered near the Orange River, in South Africa, where diamonds were soon being scooped out by the ton. Suddenly, the market was deluged with diamonds."

"The major investors in the diamond mines created the instrument in 1888 called De Beers Consolidated Mines, Ltd., and incorporated in South Africa. De Beers proved to be the most successful cartel arrangement in the annals of modern commerce. The diamond invention is far more than a monopoly for fixing diamond prices; it is a mechanism for converting tiny crystals of carbon into universally recognized tokens of wealth, power, and romance ..."A Diamond Is Forever" became the official motto of De Beers."

"The Koh-I-Noor is at present decidedly the lion of the Exhibition. A mysterious interest appears to be attached to it, and now that so many precautions have been resorted to, and so much difficulty attends its inspection, the crowd is enormously enhanced, and the policemen at either end of the covered entrance have much trouble in restraining the struggling and impatient multitude. For some hours yesterday there were never less than a couple of hundred persons waiting their turn of admission, and yet, after all, the diamond does not satisfy. Either from the imperfect cutting or the difficulty of placing the lights advantageously, or the immovability of the stone itself, which should be made to revolve on its axis, few catch any of the brilliant rays it reflects when viewed at a particular angle."

"Yeah, it's tough being smart and sexy, too. I have to say, I'm really not that attractive. Until I met my husband, I could not get a date. I promise you it's true. My husband Jeff Richmond saw a diamond in the rough and took me in."

"There are three things extremely hard: steel, a diamond, and to know one's self."

"A diamond is a portion of crystalized carbon. That is what we have all been for so many years admiring; that is what the Greeks call adamas (the unconquerable) that is what Mrs Jones calls “a diamont,” and to which all sorts of poets and lovers have likened the prettiest and sweetest, and brightest eyes which ever shone."

"You're a shooting star I see A vision of ecstasy When you hold me, I'm alive We're like diamonds in the sky At first sight I felt the energy of sun rays I saw the life inside your eyes So shine bright, tonight you and I We're beautiful like diamonds in the sky Eye to eye, so alive We're beautiful like diamonds in the sky Shine bright like a diamond Shine bright like a diamond Shining bright like a diamond We're beautiful like diamonds in the sky"

"It is scarcity and plenty that make the vulgar take things to be precious or worthless; they call a diamond very beautiful because it is like pure water, and then would not exchange one for ten barrels of water."

"Allow God to use the difficulties and disappointments in life as polish to transform your faith into a glistening diamond that takes in and reflects His love. What beauty he will create."

"Perhaps time’s definition of coal is the diamond."

"Over the years, the diamond industry has had a devastating impact in countries such as Sierra Leone, Angola and the Congo, where profits from the sale of diamonds have been used to fund brutal wars, with disastrous effects on local communities."

"Unsurprisingly, in these more eco-aware times, interest in ‘ethical diamonds’ is also growing. Two organisations, Amnesty International and Global Witness, have worked over the past few years to help the jewellery industry: it’s a real victory for human rights that it’s now illegal to trade in conflict diamonds, and any government trading in diamonds must certify that shipments of uncut diamonds are conflict-free."
