Are DeBeers Diamonds Forever?
First, let's start with easier questions: why are diamonds - little stones - so expensive? Are diamonds really that rare?
The answer is, "No." There is an area in South Africa. for example, that's estimated to hold 3-4 times more diamonds than all of the diamonds on fingers today. That area is mined, but not to extract diamonds. It's mined with landmines, fenced with barbed wires and patrolled by armed guards with orders to shoot trespassers.
Why? Because that area, as well as over half of the world's supply of diamonds are controlled by DeBeers Diamonds. A South African multinational, DeBeers Diamonds has long monopolized the world's diamonds. By limiting the supply of diamonds, DeBeers Diamonds keeps their prices high and profits inflated.
And do you know when diamonds became the de facto requirement for engagement rings? It wasn't until the early 20th century when DeBeers Diamonds launched a brilliant marketing campaign under a slogan that branded diamonds as the sign of love forever. What was the DeBeers' slogan? "Diamonds are forever!"
When buying diamonds, Debeers' or otherwise, there is no point in paying for color designation below "J" and clarity below "SI2." Why? Lower designations cost much more but the difference can only be seen under a gemscope's 10x magnification.
Unless you or your friends have bionic eyes, it's absurd to pay many times more for something that can't even be seen. Sure some women will compare their diamonds' imperceptible designations and jewelers will suggest that the diamond ring you buy should be as pure as your love, but don't listen to their nonsense.
Instead of spending $10,000 on a VSI2 G diamond ring, spend $5,000 on a same-sized, SI2 J diamond that will also look totally colorless and free from birthmarks. If planning to spend $20,000 on a VVSI1 D diamond, you can save $15,000 for the same-sized diamond that looks just as clear and colorless, etc.
