- Frances Gerety, copywriter at N. W. Ayer & Son, the primary advertising agency within the US.
What makes a diamond so valuable? First, is its extreme rarity. On an average, one hundred tons of rock need to be mined to extract 2 grams of diamonds. Second, is its extreme magnificence. There are just a few parameters to determine a diamond's value - the 4 Cs (carat, minimize, coloration, and clarity), shape and fluorescence. A diamond's history also affects its price. Many of the most famous, and valuable, diamonds right this moment are usually not necessarily massive, but they are undoubtedly of immense historic significance. Case in point: the Kohinoor and the Hope Diamond. After all, there are some just like the Cullinan, which are well-known by dint of their sizes alone.
A carat is a unit of measurement equal to 200 mg or zero.007055 ounces. In addition to diamonds, carats are also used to measure different valuable stones and pearls. The word comes from the Greek phrase for the carob seed, historically utilized by jewelers as weights on scales for his or her reputed similarity in weights. The cut of a diamond is the style used when shaping a diamond for polishing. A properly-minimize diamond is very luminous. The most typical type is the round good, followed by fancy cuts reminiscent of modified brilliants, step cuts, mixed cuts, and rose cuts.
A chemically pure diamond is totally transparent. Small quantities of impurities like boron and carbon usually contribute to vivid colors like blue, yellow, pink, purple, and so forth. Depending on the hue and intensity of a diamond's coloration, a diamond's shade can either add to or subtract from its worth. Out of all colored diamonds, the red ones are the rarest. The fourth parameter affecting the worth of a diamond is clarity, the standard of its appearance contemplating internal traits referred to as inclusions and floor defects referred to as blemishes. More the clarity, higher the price, with the exceedingly rare "flawless" graded diamond fetching the highest price.
Now we come to the ultimate issue figuring out value - historical past. Nearly all of the costliest diamonds have fascinating histories - indeed, the history of diamonds is the history of mankind. Right from historical times in India where they have been first discovered to trendy times when diamonds can be created artificially, diamonds have been an integral part of human civilization. But even right this moment, as centuries in the past, nothing says "I love you" as eloquently as a diamond ring.
The phrase "diamond" originates from the Greek "adamos", that means "unbreakable". Indeed, diamonds are the hardest naturally-occurring substances. Basically made of carbon, the same material of which charcoal is composed of, diamonds are created over billions of years round one hundred miles below the surface. Diamonds have comparatively excessive optical dispersion (means to disperse light of different colors) and refractive index (potential to bend mild when it passes through) which result in the attribute luster.
When Mr. Gerety coined this slogan in 1947 for diamond distributing big De Beers, he could not have dreamed that his words, like the item of its adulation, would turn into "endlessly". Such is the popularity of this amazing piece of advertising creativity that in 2000, Promoting Age journal named "A Diamond Is Endlessly" the most effective advertising slogan of the 20th century. The phrase has also been immortalized within the in style lexicon by the eponymous James Bond movie "Diamonds are Eternally". And rightly so. Not like different gadgets of worth, a diamond doesn't rust, decompose or wither away. Originating within the deepest reaches of the Earth and cast by great warmth and strain, a diamond is indeed endlessly.
