How Are Lab-Grown Diamonds Graded?
If you're exploring lab-grown diamond jewelry, understanding how these stones are graded is essential. These diamonds come in a wide spectrum of color, clarity, shape, and size - just like mined diamonds.
At Auric Charms, we proudly offer high-quality, ethically produced lab-grown diamonds set into beautifully crafted designs. Knowing how these diamonds are graded can help you confidently choose the perfect piece to match your personal style and values.
The 4Cs of Lab-Grown Diamonds
Lab-grown diamonds are graded using the same 4Cs as mined diamonds, based on the globally recognized standards developed by the Gemological Institute of America (GIA):
Cut - Evaluates the diamond’s angles, symmetry, and brilliance.
Color - Measures the lack of color; the less color, the higher the grade.
Clarity - Indicates the number and visibility of internal or surface inclusions.
Carat Weight - Refers to the actual weight of the diamond, not the size.
Because lab-created diamonds are identical to mined diamonds chemically and optically, they follow the same grading system.
Most pieces at Auric Charms include certification from GIA or IGI (International Gemological Institute). These reports help customers understand the exact quality of their stone and ensure they’re making an informed decision.
Cut: The Key to Sparkle
Among the 4Cs, cut is often considered the most important—it determines how brilliantly a diamond reflects light. A diamond with excellent cut proportions will shine with intense sparkle, fire, and brilliance.
At Auric Charms, we focus on Ideal and Excellent cuts, as these deliver exceptional radiance and visual appeal. Whether you're purchasing an engagement ring or diamond studs, brilliance begins with the right cut.Color: The Whiter, the Brighter
Diamonds are graded for colorlessness on a scale from D (colorless) to Z (noticeable yellow tint). Most people prefer diamonds that appear icy white or near-colorless.
Our curated lab-grown diamonds typically range from D to G, giving you a luminous, clean look that pairs beautifully with any gold tone - be it white, yellow, rose, or platinum.
Clarity: A Glimpse Into the Stone
Clarity evaluates how free a diamond is from natural imperfections known as inclusions (inside) or blemishes (surface).
At Auric Charms, most of our lab-grown diamonds are VS2 and above, ensuring exceptional brilliance with no visible inclusions to the naked eye.
Carat: Measuring Weight, Not Just Size
The carat is a weight measurement-1 carat = 200 milligrams. Larger carat weights generally cost more, but size perception can also vary depending on the diamond cut and setting.
Whether you're looking for a delicate 0.50ct ring or a show-stopping 5ct tennis bracelet, Auric Charms offers flexible options. We help you choose the right size based on your preferences and budget-without compromising on sparkle or quality.
Certification: Trust the Grade
Every certified lab-grown diamond is accompanied by a grading report issued by leading gemological institutes like GIA or IGI. This report includes details on the 4Cs, symmetry, polish, and fluorescence.
Lab-grown diamonds are certified by internationally recognized grading labs, just like mined ones.
Most Trusted Grading Labs:
GIA (Gemological Institute of America)
IGI (International Gemological Institute)
These institutions inspect each stone and provide a detailed grading report, often with laser-inscribed serial numbers on the girdle for security and authenticity.
At Auric Charms, we offer IGI certification upon request, so you always know the authenticity and quality of your chosen diamond. Each report reflects the craftsmanship and excellence behind your piece.
