Lab-Grown Diamonds vs. Earth-Mined Diamonds: Everything You Need to Know
When shopping for a diamond—especially for a custom engagement ring, anniversary gift, or fine jewelry—you’ll often face one big question:
Should I choose a lab-grown diamond or a natural earth-mined diamond?
At Everglow Jewelry, we specialize in both lab-grown and natural diamonds, helping customers across Tampa and surrounding areas find the perfect stone for their budget, values, and style.
Here’s your complete guide to lab-grown vs. natural diamonds, including the differences in price, appearance, quality, and ethics—so you can make an informed and confident decision.
💎 What Are Lab-Grown Diamonds?
Lab-grown diamonds (also called man-made or cultured diamonds) are real diamonds—just like natural ones—but created in a controlled laboratory environment rather than mined from the earth.
They are made using two high-tech methods:
HPHT (High Pressure, High Temperature) – mimics the conditions in the earth's mantle
CVD (Chemical Vapor Deposition) – grows diamond crystals layer by layer in a chamber of carbon-rich gas
The result? A real diamond with the same crystal structure, chemical makeup, and sparkle as a mined diamond.
🌍 What Are Natural (Earth-Mined) Diamonds?
Natural diamonds form deep within the Earth over billions of years through intense heat and pressure. These diamonds are then extracted through mining—sometimes from deep underground or via alluvial (riverbed) deposits.
They carry a certain mystique and history, having been shaped by nature over eons.
🔬 Lab-Grown vs. Natural: Key Differences
1. Appearance
Both look identical to the naked eye
Both score a 10 on the Mohs scale (the hardest material on Earth)
Both can be colorless or fancy colored, depending on how they're grown or formed
At Everglow Jewelry, our GIA- and IGI-certified diamonds, whether lab-grown or mined, meet high standards in cut, clarity, color, and brilliance.
2. Price
Lab-grown diamonds cost 40–70% less than their earth-mined counterparts of the same size and quality
This means you can go bigger or higher quality for the same budget
💡 Example: A 1.50ct natural diamond may cost $8,000, while a lab-grown of the same specs might cost $2,500–$3,000.
3. Value & Resale
Earth-mined diamonds tend to hold more resale value over time, due to their rarity and long-standing demand
Lab-grown diamonds currently have lower resale value, though that may change as the market evolves
If your goal is sentimental value and beauty—lab-grown is often perfect. If you’re concerned with investment or heirloom value, natural might be your choice. However, keep in mind that natural diamonds do not hold value in the short term. Someone purchasing a $10,000 natural diamond may be offered only 10-50% of that if they try to sell it back to a jewelry store.
4. Environmental & Ethical Impact
Lab-grown diamonds are:
Conflict-free by default
Require less land and water
Produce fewer carbon emissions than many mining operations
Natural diamonds can be ethically sourced, especially when certified through the Kimberley Process, but they still involve significant environmental and social concerns.
🌿 At Everglow Jewelry, we offer conflict-free mined diamonds and promote lab-grown options for customers focused on ethical sourcing.
5. Certification & Grading
Both types are graded using the 4Cs: Cut, Color, Clarity, and Carat
Labs like GIA (Gemological Institute of America) and IGI (International Gemological Institute) certify both lab-grown and mined stones
We always recommend purchasing certified diamonds—and we’ll walk you through how to understand each certificate.
