The embodiment of elegance and all things chic, black is arguably the most loved color in fashion. It should come as no surprise that black diamond engagement rings have emerged as one of the hottest wedding ring trends among "it" girls in recent years. Bold, glamorous and a little bit mysterious, these gray to black versions of natural diamonds are a gorgeous option for the bride searching for a unique engagement ring. After all, Mr. Big proposed to style icon Carrie Bradshaw with a a five-carat black diamond Itay Malkin ring set in 18-karat white gold (if we're being specific) in the 2010 movie Sex and the City 2, catapulting these unique gemstones into the mainstream.

Their trendy status aside, black diamonds are also a wise choice for to-be-weds on budget, as they tend to cost less than traditional white diamonds. Another plus? They're also surprisingly versatile. Whether surrounded by a halo of smaller white diamonds, the dazzling center stone of a solitaire ring setting or a more subtle accent stone in a wedding band, there's a black diamond ring style for everyone.

What Does a Black Diamond Engagement Ring Mean?

We've established black diamond rings are synonymous with a killer sense of style, but their significance is much deeper and more sentimental than cool girl appeal. For centuries, diamonds have symbolized flawless, eternal and unchanging love, making them the preferred stone for engagement rings for obvious reasons. Given that black diamonds are also real diamonds, all of these romantic characteristics of white diamonds can also be applied to black diamonds. And, due to the intense, color that sets them apart from white diamonds, black diamonds are also associated with passionate love and strength.

Is a Black Diamond a Real Diamond?

While they may not have the same brilliance (read: out of control sparkle) as white diamonds due to their dark color, black diamonds are real diamonds. Most naturally colored black diamonds get their color from large amounts of dark-colored mineral inclusions (also known as internal flaws) made of graphite, pyrite or hematite that occur as the stone is forming in the earth's crust. These diamonds may also have fractures that are stained black or have become black over time. Natural black diamonds are typically opaque, with a luster that makes them appear almost metallic. Fun fact: Most of the black diamonds sold for fine jewelry and engagement rings have been treated with a high-temperature/low-pressure treatment to enhance their black color.
