Lab-grown diamonds have become a hot topic in jewelry over the last 25 years, and have become a significant category in the past decade. Mined diamonds are believed to be formed between 1 to 3.3 billion years. Lab-grown diamonds can be grown in weeks! We’ll explore the history of lab-grown diamonds, the differences between mined and lab-grown diamonds, how they are grown, and help you decide if the next diamond you buy or consider might be lab-grown.
This offering meets for a total of 1 session(s).
