There is actually a huge historical significance to diamonds, dating back to when we did not have all of the mining tactics that we know today and when the use of loose diamonds was not limited to diamond rings, earrings and necklaces/pendants. Their scarcity and high price tag have a lot to do with it too. But back in the day, diamonds were available only to the elite.
The brilliance of diamonds are unsurpassed by any other precious gem or metal. When well cut, a diamond sparkles with a million rainbows.
Yes, throughout history it has been shown that humans love what is rare or expensive as it makes them feel significant to own what others cannot.
The sparkle catches the eye. I love the way sunlight is fragmented into rainbows. But crystal has the same quality. I don't even own a diamond. My husband bought diamond earrings and a bracelet but they got stolen/misplaced/lost a long time ago.
That happens to all of my jewelry for some reason. My mom gave me a ruby, my grandmother pearls, another relative gave me an opal. I love gems but they float off somehow...
Every person will have his/her own opinion about diamonds. The fact is, however, that most diamonds in this world are mined legally and ethically. Those who supply unethical diamonds find it rather difficult to make sales, because, fortunately the laws are getting more and more stringent with regard to conflict diamonds.
And we even work with Human Rights Watch, a BBB accredited organization that educates the masses on crimes against humanity. Diamonds are a major topic for them.
