Because they're made with a predictable supply chain, lab created diamonds are usually less expensive than mined diamonds. The downside? They may decline in value as supply increases.
The only difference between a lab-grown diamond and a mined diamond is that one comes from a high-tech lab and one comes from within the earth. Both types will last a lifetime and more.
Lab-grown diamonds have the same chemical properties as mined diamonds — they're just as sparkly, full of light, and you can't see any difference at all with the naked eye.
Lab-grown diamonds are graded on the 4 C's just like natural diamonds: Color, Cut, Clarity and Carat. Lab grown diamonds have to meet the same quality criteria.
Moissanite is a strictly lab-grown gemstone that's nearly as hard as a diamond, and is a very affordable alternative. It's known for sensational color and fire. In fact, Moissanite's refractive index is higher than a natural diamond, producing more sparkle and brilliance.
Lab-grown diamonds are somewhat harder, so if you're concerned about wear, go with a lab-grown or mined diamond. Diamonds have a certain mystique, there's no denying it. And now lab-grown diamonds come in a world of colors.
Some people prefer mined diamonds because there's a certain mystery to a stone that has taken millions of years to create. With lab-grown or mined you'll know exactly where your diamond came from, and have certification for the 4C's.
Do lab grown diamonds test as real diamonds?
Lab grown diamonds are “real” diamonds in the sense that they have exactly the same chemical composition, hardness, and durability as earth-grown diamonds that come from a mine. But a diamond expert using professional equipment can see the difference.
Do lab-grown diamonds last as long as earth-grown diamonds?
Yes, because lab grown diamonds are exactly the same chemically and physically, they last just as long. The only difference is that they are made in a high-tech machine rather than deep in the earth. They don't turn yellow, or fade, or become cloudy.
Are lab grown diamonds flawless?
Lab grown diamonds can be flawless but they are rare, just as with mined diamonds. The growing process starts with a tiny diamond "seed," and most lab grown diamonds have some imperfection or flaw. That’s why they’re graded for color, clarity, cut, and carat just like natural diamonds.
Which is better, lab grown or "natural" earth-grown diamonds?
It depends on what your priority is. Mined diamonds help support communities in mining countries by bringing income to those areas, and there’s a certain mystery to knowing your diamond was created over millions of years. On the other hand, lab grown diamonds are made without mining, which some people consider destructive to the earth. As for resale, there's a chance a lab-grown diamond won't retain its original value as more are made and supply increases. But most people buy their diamond ring for a moment in time, not to count on reselling it sometime in the future.
