As with any significant investment, you will want to do your research — and an engagement ring is a huge investment. When shopping for lab-grown diamonds, there’s a lot to consider between the shape, setting and band to the retailers and jewelers behind them.
If you couldn’t guess by the name, lab-grown diamonds are just that: Diamonds produced in a lab using technology that mimics the conditions that create natural diamonds. The result is a sparkly rock identical to a diamond that anyone would drool over.
First introduced to the market in the 1980s, lab-grown diamonds have long received a skeptical side-eye. How could something compete with a diamond from the earth? But consumer interest has grown exponentially thanks to affordable pricing, eco-friendly technology and ethical production practices.
Nowadays, there are so many ways you can shop for a lab-grown diamond engagement ring. Online retailers, in particular, have grown in popularity. With a range of styles, shapes, production practices and customization options and overall value, you won’t be disappointed with your options.
Before you start throwing your credit card at any retailer with a pretty picture of a dazzling diamond, a few questions need answering.
Are lab-grown diamond rings real?
Lab-grown and naturally mined diamonds appear identical to the eye, with brilliant cuts and stunning sparkle in direct light. However, one is the work of billions of years while the other is grown in a laboratory — so how could they be the same?
Let’s break it down: A lab-created diamond is “grown” inside a lab using technology that replicates the natural diamond growing process. The result is a man-made diamond that is chemically, physically and optically the same as those mined from the earth.
Each lab-grown diamond gets graded on the same famous 4Cs scale as natural diamonds: cut, clarity, color and carat. The stones also match their counterparts in hardness and durability.
TL;DR: Yes, lab-grown diamonds are absolutely real diamonds.
What are the benefits of buying a lab-grown diamond ring?
Lab-grown diamonds are obviously very new to the market than naturally mined diamonds. Still, there are so many financial and sustainable benefits to choosing a lab-grown diamond engagement ring.
1. Affordable pricing
Lab-grown diamonds skip the whole mining process of natural diamonds, including miners, distributors, cutters, polishers, jewelers and retailers. Since fewer hands are involved, the production cost is much smaller.
2. Ethically sourced
The United Nations defines these natural diamonds as “those mined in areas that are not under the control of any internationally recognized government and sold to finance a violent uprising against that government.” Per the World Diamond Council, purchasing a lab-grown diamond ensures that the stone did not contribute to the violation of universal human and labor rights.
The process of diamond mining has a significant impact on the environment. Made using technology that simulates a natural diamond’s creation, each lab-grown diamond uses less energy than digging diamonds out of the ground. Many companies also use renewable energy sources, leaving behind zero carbon emissions.
