A Complete Guide to Lab-Grown Diamond Certification & Quality — Everbrite Jewellery

As lab-grown diamonds gain popularity, customers are increasingly seeking assurance about their quality, authenticity, and value. At Everbrite Jewellery, we believe in transparency and education—empowering our customers to make confident decisions when purchasing lab-grown diamond jewelry.

In this guide, we'll take a deep dive into lab-grown diamond certification and quality grading. You'll learn what makes a high-quality lab-grown diamond, which certifications matter, and how Everbrite ensures you get only the best.

What Are Lab-Grown Diamonds?

Lab-grown diamonds, also known as cultured or synthetic diamonds, are created using high-tech processes that replicate the conditions under which natural diamonds form. The result? A real diamond—chemically, physically, and optically identical to those mined from the Earth.

Unlike simulants like cubic zirconia or moissanite, lab-grown diamonds are 100% real diamonds, just made in a lab. At Everbrite Jewellery, every piece is crafted with high-quality, certified lab-grown stones.

Why Certification Matters

Just like mined diamonds, lab-grown diamonds are graded by independent gemological labs for their quality. A diamond certificate (or grading report) verifies the diamond’s characteristics and assures you of its authenticity.

Key Benefits of Certification:

• Confirms the diamond is lab-grown

• Provides objective grading for the 4 Cs (cut, clarity, color, carat)

• Helps compare stones more accurately

• Increases resale and insurance value

At Everbrite Jewellery, we provide full certification details with every purchase, ensuring complete peace of mind.

The 4 Cs of Diamond Quality

When choosing a lab-grown diamond, understanding the 4 Cs is essential:

1. Cut

Cut affects how brilliantly the diamond sparkles. It’s not about shape but how well the stone reflects light.

• Grades: Excellent, Very Good, Good, Fair, Poor

2. Color

Diamonds are graded from D (colorless) to Z (light yellow). The closer to D, the more valuable the diamond.

3. Clarity

This measures internal and external flaws (inclusions and blemishes). Grades range from FL (flawless) to I3 (included).

4. Carat Weight

Carat measures the diamond's weight—not its size alone. Larger carat weights often increase the price significantly.

At Everbrite, we offer diamonds with a balanced combination of these qualities, always accompanied by grading reports.

Which Labs Certify Lab-Grown Diamonds?

Several trusted gemological institutes grade and certify lab-grown diamonds. These organizations use advanced tools and strict standards to evaluate diamonds independently.

Top Certification Authorities:

• IGI (International Gemological Institute)

• GIA (Gemological Institute of America)

• GCAL (Gem Certification & Assurance Lab)

• HRD Antwerp

At Everbrite Jewellery, we primarily use diamonds certified by IGI and GIA—the two most widely respected labs in the world.

How Are Lab-Grown Diamonds Graded?

Lab-grown diamonds go through the same grading process as natural diamonds. Grading is typically done under 10x magnification and includes:

• Optical inspection

• Laser inscription (for traceability)

• Spectroscopic analysis (for origin verification)

• Precise measurements of cut proportions

Each diamond comes with a report number and may have a laser-inscribed code on its girdle to match it with its certificate.
