Lab-Grown vs. Natural Diamonds: The Purity Truth

Type I diamonds (90% of natural stones) contain nitrogen.
Type IIa diamonds are the purest. No nitrogen, just pure carbon.
Here’s the twist: most CVD lab-grown diamonds are Type IIa, making them chemically more flawless than the vast majority of mined diamonds.
So while the industry says lab diamonds are “less than,” the science says otherwise.
