The latest betrothal trend is stunning black diamond engagement rings. Black diamonds, found only in diamond fields in Central Africa and Brazil, are among the rarest and oldest diamonds in the world– a perfect metaphor for the uniqueness of your love!
Black diamonds look especially stunning in non-traditional metals like titanium and white gold (or both). For many years black diamonds were out of fashion, as they are even harder than regular diamonds and require extreme skill and precision to make them into jewels.
Although diamonds are found all over the world, black diamonds are only found in two relatively small regions. And in fact, due to the similarities in the bedrock in both Brazil and Central Africa, geologists think that they might have been the same region at the time that the diamonds in them were formed.
An even more far-out theory is that the reason that black diamonds are only found in such a tiny area is that they were a part of an asteroid that struck the earth — meaning that the black diamonds in those areas represent all the black diamonds on earth, ever.
In any event, black diamonds are extremely old; geologists estimate between 2.6and 3.8 billion years old (conventional diamonds might be a mere billion years old.)
Black diamonds are black because, unlike conventional diamonds which have a single-crystal structure that easily refracts light, black diamonds are made of many thousands of crystalline structures, all smooshed tightly together in one extremely hard package (only a black diamond can cut another black diamond).
Because they cannot refract light, black diamonds are generally cut in round- or cushion-cut shapes so that the deep black color can be more easily admired. If you want a unique, out-of-this-world symbol of your love, you can’t go wrong with a black diamond engagement ring.
