Want an easy way to save 3+ months' salary? Don't buy a diamond engagement ring. If your fiancé, friends and family scream hellfire, calmly explain:
It's just marketing. The whole "A Diamond is Forever" and the idea of a diamond engagement ring is not an ancient tradition to be revered and followed. It is Sprite's "Obey Your Thirst." It is Nike's "Just Do It." It is Gary Dahl's "Pet Rock." Not only did De Beers understand it had to control supply (buying up and closing down any diamond mine discovered), they had to control demand. They had to make it sentimental. And Americans were the perfect suckers. They targeted the US specifically for our marketability. This campaign is less than 70 years old yet has become so ingrained in our culture that the diamond engagement ring has become the ultimate symbol of how much the relationship, the girl, and love itself is worth.
Diamonds aren't rare. Fine, using marketing tactics can't be blamed since that's part of the game of capitalism. But another part of the game is competition. It's all well and good if marketers can convince consumers to buy them instead of the competition based on a nice slogan, but the competition should be there to protect the consumer. All gems are valued based on their rarity (as are most things in life). But diamonds are abundant. De Beers has a huge vault where they keep most of the world's supply of diamonds. If it ever got released into the market, the way it would be if they weren't a monopoly, diamonds would be worth nothing. It's literally a pretty rock.
Diamonds have no resale value. The reason a "diamond is forever" is because you're basically stuck with it. You'll never be able to resell it except to a pawn shop. Even a jeweler (the few who would be willing to buy it) would offer a fraction of what you paid.
Synthetic diamonds will flood the market. Synthetic or "cultured" diamonds are already being made and within the next few years, will be efficiently made for the mass market. These are real diamonds. They are made in a machine that replicates the environmental forces that make diamonds. The only difference is that they're better. They have less flaws. And they cost a fraction of the going rate. Want a 2-carat pink diamond? That'll be a few thousand dollars.
Who is the ring for, anyway? Seriously.
As The Dilettante so poignantly put it, It's fun to show off for about 30 seconds. After that there is little to show for the debt incurred for the shiny piece of rock. That money could have gone into furniture, an amazing trip (or many nice ones), your future kids' college funds!!
Are these reasons still not enough?
Watch Blood Diamond. It is high time Hollywood dared to broach the subject of diamonds, especially when they had a hand in marketing it to the public in the first place. Blood Diamond, is an explicit example of the blood and war that has spanned the entire history of the De Beers' diamond cartel. The story of Sierra Leone isn't an isolated event, nor is the conflict over just because the movie says there's peace in Sierra Leone now.
What are conflict/blood diamonds? Conflict/blood diamonds are used by rebel groups to fuel conflict and civil wars, and by terrorist groups to finance their activities.
