Diamonds, the hardest naturally occurring substance on Earth, can take up to 3.5 billion years to form – a considerable portion of the planet’s 4.5-billion-year age.
In a lab, technicians can create a diamond within days.
And when it comes to buying a diamond for an engagement ring or other piece of jewelry, the human-made counterparts are available at a fraction of the cost.
Without the aid of specialized equipment, even a trained gemologist can’t tell the difference.
Unlike cubic zirconia and other imitations, lab-grown diamonds are chemically identical to those that come out of the ground.
Nevertheless, the lab-grown gems are expected to make up only about 15% of diamond sales by 2020, according to a Morgan Stanley article.
That discrepancy leaves many wondering: Are lab-grown diamonds better than Earth-grown diamonds?
