Diamonds–a statement of affluence, glamor, and style– are just one way that celebrities solidify their celebrity status. Whether they’re popping out for a coffee or walking the red carpet, we hope that they’re bejeweled, and we love to learn about the jewels they’re flaunting. 

However, celebrities aren’t just choosing their diamonds based on the size anymore but are letting ethical considerations guide their choices. As ethical concerns about traditionally-mined diamonds grow, many celebrities are turning to lab-grown diamonds. So what are lab-grown diamonds and why are they preferable to the alternative? And which celebrities have added them to their jewelry boxes?

What Are Lab-Grown Diamonds?

Lab-grown diamonds, sometimes called synthetic diamonds or cultured diamonds, are diamonds that are grown in a lab, and not mined from the ground. Lab-grown diamonds can be created through a number of techniques, but the most common technique is to start with a small diamond crystal and then grow new diamond crystals on top of it.

Lab-grown diamonds have essentially the same chemical and physical properties as natural diamonds, and they are nearly impossible to distinguish from mined diamonds. Mined diamonds will often contain trace amounts of chemicals that can slightly alter their appearance, however, only trained gemologists can tell the difference, even under a microscope.  The only way that a layperson can tell them apart is by their price tag; lab-created diamonds are typically much more affordable than natural diamonds.

These diamonds are becoming increasingly popular, especially for those who want a socially responsible alternative to mined diamonds.

Why Lab-Grown Diamonds

Many may not have known much about the diamond mining industry prior to the 2006 release of the film Blood Diamond, starring Leo DiCaprio. DiCaprio plays a diamond smuggler who has landed himself in jail after smuggling diamonds mined by rebel groups to international diamond traders. He secures his escape from jail with the intent to continue smuggling, and along the way witnesses forced labor and the kidnapping of children conscripted to become child soldiers, all at the hand of the rebel groups for whom he has been smuggling. 

Though not based on a true story, the film accurately documented human rights abuses that had been codified by the United Nations years before the film came out. In the 1990’s the United Nations formulated the definition of “blood diamonds” or “conflict diamonds” to refer to diamonds that were being mined by rebel groups to fund civil wars. The film ends with a character testifying at the Kimberle Convention, which was also based on true events. 

In 2003, The Kimberley Process was established as a certification program for the diamond industry. The process’s mandate is to increase trade transparency and abolish all forms of conflict diamonds. The initiative has faced criticism of its lack of efficacy, however, civil wars in diamond-rich African countries have largely ceased, and areas that were once controlled by rebel forces are now back in the hands of internationally-recognized governments. So conflict-diamonds have become rarer, though not necessarily as a result of international diplomatic efforts.

Still, human rights abuses have been documented outside of conflict zones too, and the world is becoming increasingly aware that the entire diamond industry is fraught with exploitation. The impossibility of knowing whether or not a diamond was mined ethically has led many people to seek alternatives. 

Lab-grown diamonds are not without their own issues. Critics have noted that the environmental impact of growing diamonds is significant, given the amount of energy required during production. Some diamond producers are switching to renewable energy to lessen the negative environmental impact.

Maybe all of this is enough to convince you to do away with diamonds altogether (we think that a nice Swarovski can take the place of a diamond, real or lab-grown in most cases). But if diamonds are a must for you, consider following the lead of these celebrities who rock and support lab-cultured diamonds.
