NATURAL VS. LAB-GROWN DIAMONDS: WHICH SHOULD YOU BUY?
“Diamonds are a girl’s best friend” sang Marilyn Monroe in a 1950s jazz hit. Is the saying still true? We’ll let you decide. But what we can tell you is that there is a real change in how diamonds are now created. Natural diamonds are created from the Earth’s natural resources, mined from the result of billions of years of underground activity. But a new form of production is taking over: labgrown diamonds. Production Of Lab-grown Diamonds Similarly to mined diamonds, laboratory-grown diamonds are created under maximal pressure and heat. The crucial difference is that mined diamonds are created when carbon, hundreds of miles below the earth’s surface, undergoes immense pressure over time combined with the heat from intense volcanic eruptions.
These eruptions release heat, pushing large rocks closer

MAKING THE DECISION BETWEEN MINED OR LABGROWN DIAMONDS IS DIFFICULT, AND WHILE THERE ARE MANY PRO’S AND CON’S TO BOTH, ULTIMATELY IT COMES DOWN TO PERSONAL PREFERENCE. HOWEVER, WE’D ULTIMATELY HAVE TO RECOMMEND THE LAB-GROWN DIAMOND DUE TO THE ETHICAL AND SUSTAINABILITY BENEFITS.
