What to Look for When Buying Lab-created Yellow Diamonds

Here's the things to keep an eye out for when looking for yellow lab-grown diamonds online: 

Cut & Carat

We often put having the best cut grade above anything else with colorless diamonds. It controls the overall brilliance and beauty of your white diamond

It’s different with colored diamonds. Instead of round diamonds being the best shape-they're actually the worst shape for colored diamonds. 

The best diamond shapes for yellow diamonds are radiant cuts, cushions, or ovals.

Here's why...

These shapes display diamond color much better than a round yellow diamond. You should avoid them because the color is diffused. 

Don’t worry about the cut grade. You should be looking at its length-to-width ratio and other proportions to see if it matches the “ideal grades” for that diamond shape. 

Like all diamonds, the price of a lab grown yellow diamond will rise as you increase carat weight. However, the increase isn’t too bad if you’re starting lower, like from a carat to a 1.5 or carat diamond. Going from a carat to a 4 carat will cost you a pretty penny. 


Lab-grown yellow diamonds should be eye-clean, or free of inclusions. Inclusions happen during the formation process. 

Natural diamonds have a variety of different inclusions, but lab grown diamonds have metallic inclusions instead of crystal inclusions. Those types of inclusions aren’t as noticeable. 

Most of the eye-clean lab-grown yellow diamonds I’ve seen have SI clarity. 


Fancy colored diamonds are graded by the 4Cs, but their color has special grades too. Colored diamonds are assessed by their tone, saturation, and color hues. 

Light yellow diamonds are very popular and less expensive. Yellow lab diamonds are most often a vivid yellow since those are in demand and go for higher prices. All they have to do is introduce nitrogen atom to the pure carbon atom

The most valued lab-yellow diamonds are going to have a bright yellow look throughout the stone. A yellow diamond that has no orange or brown in it is considered top-quality (even if you’re like me and love that orange swirl color).

Gemologists call these canary diamonds, and they are still a lot cheaper than blue lab created diamonds.

How to Get the Best Deal When Buying Lab-Created Yellow Diamonds Online

There are a some things  to consider when purchasing a lab-created yellow diamond online. 

  • Assess the clarity of the stone and its overall size - any inclusions or small blemishes will affect the price of the diamond. 
  • Determine what shape you're looking for - round cuts are popular but also more expensive than other shapes. 
  • Make sure your lab yellow diamond is certified.
  • Buy from a retailer with a 360˚ view.
  • Choose shapes like radiants, cushion cuts, or ovals for yellow diamonds
  • Make sure your length to width ratio and other diamond proportions matches your chosen diamond shape.
  • Compare prices of different retailers.

You'd also do well to remember the following things:

  • Remember that a synthetic diamond isn't an artificial diamond, it's a real diamond.
  • A man-made diamond costs much less than an earth made diamond.
  • Cultured diamonds have better hardness than any diamond simulant, like moissanite or cubic zirconia.

Grading Report

You’ll want to make sure the stone you’re getting is indeed a lab created yellow diamond. The best way to ensure that is through a grading report from a reputable lab. For lab yellow diamonds, we recommend GIA, AGS, HRD, and IGI grading reports.

You shouldn’t ever buy a center diamond without a grading report.

They are virtually indistinguishable from mined diamonds in terms of beauty and quality and provide an ethical alternative to mined diamonds that are conflict-free and do not harm the environment.
