Should I Buy a Lab-Grown Diamond?

Lab-created, lab-grown, or cultured diamonds are chemically and physically identical to earth-grown (“natural”) diamonds. In fact, it requires specialized equipment to determine if a diamond is natural or lab-grown. 

Lab-grown diamonds are grown under similar conditions to natural diamonds–but in a lab setting. For this reason, they do not have the environmental impacts of mining traditional stones, such as habitat degradation and water pollution. 

Further, lab-grown diamonds do not contribute to the ethical issues and human rights issues associated with the diamond trade and “conflict diamonds.”

In many cases, lab-grown diamonds do not pass through as many hands before they reach the buyer. 

For all of these reasons, lab-grown diamonds are sold at a much lower price point than natural stones.  

Further, if you always had your heart set on a colored diamond but they were always out of reach due to price, you can now purchase lab-grown colored stones for a fraction of the price of natural colored diamonds. 

Lab diamonds are also certified by GIA using the same parameters as natural diamonds. 

Best Retailers of Only Lab-Grown Diamonds

While many of the large online diamond retailers have gotten into the lab-grown diamond market (some more than others), many smaller companies are specializing in only lab-created diamonds. 

Lab-grown diamonds have gained popularity in recent years. If you think a lab-grown stone is right for you, read on for some online retailers that specialize in lab-grown diamonds that are also certified by the GIA. 

1.    Clean Origin

Clean Origin sells only lab-created diamonds, not natural stones. The site sells loose stones and engagment rings, as well as a selection of lab-made bridal jewelry.

The company also offers a 100 day return period, compared to the standard 30 day period of most online retailers. The customer service team is composed of professionals with at least 5 years’ experience in the diamond industry. 

2.    VRAI

If you are looking for a premium cut lab stone, VRAI is the place to start. VRAI grows its own diamonds in the US.

According to the website, each VRAI grown diamond saves 143 lbs of carbon dioxide, 2,011 oz of air pollution, and 250 tons of earth as compared to a mined diamond. 

In addition to growing their own diamonds, VRAI cuts the stones to exacting standards, resulting in stunning sparklers that are also good for the planet.

Shipping is often free and insured, so you aren’t taking a risk when buying online. If you don’t like what you get, you can always return it.
