What to Look For

Lab grown diamonds may be significantly more affordable than natural diamonds but they are still a major investment. Not to mention that, if you’re purchasing such a stone for an engagement ring, the quality becomes crucial regardless of the price.

So, what should you be looking for if this is your first time browsing for lab-created diamond jewelry? Here are a few pointers:

1. Always work with reputable vendors.

High-quality lab-grown diamonds are rare and in fact, according to this Forbes article, demand for quality lab diamonds exceeds supply. To avoid buying a low-quality stone, always ensure that you’re purchasing from a trustworthy retailer.

Ensure that store offers HD 3D images and/or videos of the actual diamonds and jewelry, rather than just a stock photo. Most of the retailers on our list offer personalized services, and will take the time to walk you through their inventory remotely. 

2. Check the certification.

Look for certification and HD imagery. See more lab diamonds here.

Diamonds (typically those over .30 carats) should come with a certificate of authenticity confirming the stone’s quality. These certificates are provided by certain gemological labs, some more respected than others.

In the past, lab-created diamonds didn’t use to be certified, but today, almost all labs provide certification for these stones.

We strongly urge you to only consider stones with certificates from the Gemological Institute of America (GIA), the American Gem Society (AGS), or the International Gemological Institute (IGI). With natural diamonds, the certification alone usually isn’t enough to gauge the quality of the stone, because it doesn’t fully encompass all the different characteristics and aspects of a natural stone’s inclusions and flaws. Lab-created diamonds don’t have such flaws, however, so a certificate goes even further in guaranteeing such a stone’s quality.

3. Make sure you know what you’re looking for.

Lab-grown diamonds may be more affordable than natural diamonds, but they’re still a big-ticket item. It’s best to plan on a budget, as well as the specifics of what you’re looking for before you begin to shop. It’s also a good idea to consult with an expert about the exact size, shape, and color you want from your diamond.

4. Look for vendors with solid after sales policies.

It’s essential to work with a vendor who stands by their products and offers solid after sales policies.  Look for reasonable returns policies (most stores offer 14-30 days returns on all products except customized items), as well as excellent customer service (their representatives should be easy to contact via multiple channels) and shipping policies (ideally free shipping and returns).

Wrapping Up

While there are many vendors who offer lab-created diamonds and jewelry these days, finding a retailer who offers high-quality products at reasonable prices can be difficult.

The above seven vendors are known for their commitment to customer satisfaction and product excellence. This has resulted in these stores consistently streamlining the online shopping process and offering products and services that make shopping online with them a no-brainer.
