Lab grown diamonds are changing the way people shop for fine jewelry. With growing interest in affordable, ethical, and high-quality options, many buyers now turn to lab grown diamonds instead of mined ones. In fact, lab grown diamonds now make up 10–15% of the global diamond market, and this number is expected to rise quickly.
This Lab Grown Diamond Jewelry Buying Guide will help you understand what lab diamonds are, why they matter, and how to choose the best pieces online. Whether you're shopping for an engagement ring, a necklace, or a pair of earrings, this guide will help you make a smart and confident choice.
What Are Lab Grown Diamonds?
Lab grown diamonds are real diamonds. They are created in a laboratory using advanced technology, not mined from the earth. But even though they are made in labs, they have the same physical, chemical, and optical properties as natural diamonds.
There are two main ways lab diamonds are made:
-
HPHT (High Pressure High Temperature)
-
CVD (Chemical Vapor Deposition)
Both methods produce high-quality diamonds that look just like mined ones.
Why Lab Grown Diamonds Are a Smart Choice
There are many reasons why more people are choosing lab grown diamonds:
-
Cost: Lab grown diamonds are up to 40% cheaper than mined diamonds. This means you can buy a bigger or better diamond for the same budget.
-
Ethical sourcing: No conflict zones or unsafe working conditions. These diamonds are a more eco-friendly choice.
-
Better for the planet: A study shows that lab grown diamonds use less land and water than mining does.
-
High quality: You can find larger, cleaner, and better-cut diamonds at a lower cost.
Are They Really Diamonds?
Yes! Lab grown diamonds are 100% real diamonds. They are not fake or imitation stones. They are made of pure carbon, just like mined diamonds. A top gemologist says, “Lab grown diamonds look, feel, and last just like natural ones.”
Even top brands now sell lab grown diamond jewelry, showing the industry fully accepts them.
Factors to Consider Before You Buy
Before you shop online, it's important to understand the key factors that affect quality, price, and value.
1. Budget and Pricing
Start by setting your budget. Lab grown diamonds cost less than mined ones, but prices can still vary.
-
A 1-carat lab grown diamond usually costs between $2,500 and $6,000.
-
Compare prices on trusted jewelry websites.
-
Look for discounts or bundle deals.
Tip: Always use price filters when browsing to stay within your budget.
2. The 4 Cs: Cut, Color, Clarity, Carat
Just like mined diamonds, lab grown diamonds are rated by the 4 Cs:
-
Cut: A well-cut diamond reflects light and sparkles beautifully. It’s the most important factor.
-
Color: Diamonds are rated from D (colorless) to Z (light yellow). Colorless diamonds are usually more valuable.
-
Clarity: Refers to how clean the diamond is. Look for "VS1" or better for excellent clarity.
-
Carat: This is the weight (or size) of the diamond. The bigger it is, the more it costs.
3. Certification and Authenticity
Always make sure your diamond comes with a grading certificate from a trusted lab like GIA (Gemological Institute of America) or IGI (International Gemological Institute).
-
Certificates prove the diamond’s quality and confirm it is lab grown.
-
Certified diamonds often come with higher customer satisfaction.
A customer review said, “I felt peace of mind knowing my lab diamond had a GIA report.”
4. Design and Setting Options
Once you choose your diamond, pick a design that fits your style:
-
Metal choices: Platinum, yellow gold, white gold, and silver are popular.
-
Designs: Choose between custom pieces or ready-made jewelry.
-
Popular styles:
-
Solitaire: One main diamond.
-
Halo: Small diamonds around the center.
-
Vintage: Classic, elegant designs.
