Laboratory-Grown Diamonds are increasingly available in greater quantities, higher quality and new colors at price points that many find attractive. It is no wonder then that laboratory-grown diamonds are a growing presence in the marketplace. What are they and how are they different from natural diamonds? in this article, we will cover:
WHAT ARE LABORATORY-GROWN DIAMONDS? Laboratory-grown diamonds have essentially the the same chemical, optical and physical properties and crystal structure as natural diamonds. Like natural diamonds, they are made of tightly-bonded carbon atoms. They respond to light in the same way and are just as hard as natural diamonds. The main differences between laboratory-grown and natural diamonds lie in their origin. Think of it this way: laboratory-grown diamonds are like ice from your refrigerator, while natural diamonds are like ice from a glacier. They are bot ice, although their formation stories and the age of each are very different. Natural diamonds formed millions to billions of years ago in Earth’s mantle then were explosively carried by kimberlite and lamproite volcanoes to Earth’s surface, often carrying fascinating inclusions within them. The oldest laboratory-grown diamonds are decades old; they are created in laboratories or large factories, most commonly using the High -Pressure, High -Temperature (HPHT) method or the Chemical Vapor Deposition (CVD) method. Laboratory-grown diamonds appear identical to natural diamonds to the unaided eye and typically require testing by a laboratory with advanced instruments to be identified.
