What Are Lab-Grown Diamonds? The 4Cs Certification Diamond Shapes Buying Guide FAQs

What Are Lab-Grown Diamonds?

Lab-grown diamonds are diamonds created using advanced technological processes rather than being formed naturally beneath the earth. They have the same fundamental chemical composition and crystal structure as diamonds formed naturally.

Like natural diamonds, lab-grown diamonds can be evaluated according to characteristics such as cut, color, clarity and carat weight. Their appearance can vary significantly depending on the individual diamond, which is why comparing the details of each stone is important when making a purchase.

At Genuine Diamond Shop, you can explore lab-grown diamonds in multiple shapes and quality combinations or contact us if you're looking for a specific diamond that isn't currently displayed in our catalog.

Lab-Grown Diamonds vs. Natural Diamonds

Lab-grown and natural diamonds are both diamond materials, but their origins are different. Natural diamonds form naturally beneath the earth over geological periods, while lab-grown diamonds are produced using controlled technological processes.

The best choice depends on what matters most to you. Some customers specifically want a naturally formed diamond, while others prefer the flexibility that a lab-grown diamond can provide within their jewelry budget.

Which Should You Choose?

There isn't one answer that is right for every customer. Consider your budget, preferred diamond size, desired quality, personal priorities and the type of jewelry you're creating.

If you're unsure, our team can help you compare natural and lab-grown options based on the characteristics that matter most to you.

Understanding the 4Cs of Lab-Grown Diamonds

The 4Cs—cut, color, clarity and carat—are commonly used to describe important characteristics of a diamond. Looking at all four together gives you a better understanding of the stone you're considering.

Cut

Cut describes how well a diamond's facets interact with light. Cut can have a major influence on brilliance, sparkle and overall visual appearance.

Color

Color describes the presence of body color in a diamond. Different color grades can create different visual appearances and price points.

Clarity

Clarity describes internal and external characteristics that may be present in a diamond. The importance of clarity depends on the individual stone and how visible its characteristics are.

Carat

Carat refers to diamond weight. Carat weight should not be confused with visual size because proportions and shape also influence how large a diamond appears.

Lab-Grown Diamond Certification

A diamond grading report can provide useful information when comparing stones. Depending on the individual diamond, a report may document characteristics such as carat weight, color, clarity, measurements and other grading information.

GIA & IGI Certified Diamond Options

Genuine Diamond Shop offers certified diamond options, including diamonds accompanied by GIA or IGI reports where applicable. When a diamond has a grading report, review the report details alongside the actual proportions, images and other available information before making your decision.

How to Choose a Lab-Grown Diamond

Buying a diamond isn't simply about choosing the highest grade in every category. A better approach is to decide which characteristics matter most to you and then compare diamonds within your budget.

1. Set your budget. Determine how much you want to spend on the diamond and the complete piece of jewelry.

2. Choose your shape. Decide whether you prefer a round, oval, radiant, cushion, emerald, pear or another diamond shape.

3. Consider carat weight. Think about the visual size you want rather than focusing only on the number listed as carat weight.

4. Evaluate cut and proportions. Look beyond the basic specifications and consider how the diamond performs visually.

5. Compare color and clarity. Find the balance that provides the appearance you want without paying for grades that aren't important to you.

6. Review certification. When available, use the grading report to compare the documented characteristics of the diamond.
