Natural Diamonds vs. Lab-Grown Diamonds
A Guide to Understanding the Differences
Diamonds have long symbolized love, luxury and enduring beauty. When it comes to choosing a diamond, buyers now have two primary options: natural diamonds and lab-grown diamonds. While both types of diamonds share many characteristics, there are key differences in how they’re formed, valued and appreciated. This guide will explore the distinctions between natural and lab-grown diamonds, how diamonds are evaluated and what to do if you’re considering selling your diamond jewelry.
What Are Natural Diamonds?
Natural diamonds are formed deep within the Earth’s mantle, around 90 to 120 miles below the surface, over billions of years. Through high-pressure, high-temperature conditions, carbon atoms crystallize to create a natural diamond. Volcanic activity then pushes these diamonds closer to the Earth’s surface, where they can be mined. Each natural diamond is essentially a piece of Earth’s history, taking millions to billions of years to form, making it a rare and valuable treasure.
Because of their natural origin, no two diamonds are identical. Each natural diamond has unique characteristics, such as inclusions or specific color tints, adding to its individuality. The scarcity and unique formation process of natural diamonds generally make them more expensive than lab-grown options.
What Are Lab-Grown Diamonds?
Lab-grown diamonds, also known as synthetic diamonds or engineered diamonds, are created in a controlled laboratory environment. Advanced technology replicates the natural diamond formation process, subjecting carbon to high temperatures and pressures. The result? A diamond with the same physical and chemical properties as a natural one.
Lab-grown diamonds can be produced in weeks or months, making them more readily available than natural diamonds. Although they are often less expensive than natural diamonds, lab-grown diamonds are identical in appearance and structure. This option is becoming popular for consumers seeking a more budget-friendly choice without sacrificing quality or sparkle.
Key Differences Between Natural and Lab-Grown Diamonds
While natural and lab-grown diamonds look nearly identical and are made of the same material, several distinctions set them apart:
Origin and Formation
Natural diamonds are formed over billions of years within the Earth’s mantle, while lab-grown diamonds are created in laboratories over a matter of weeks, simulating natural conditions.
Value and Resale
Natural diamonds generally have a stronger resale market due to their rarity and unique geological origins. While they can retain value well, their resale price varies based on demand, quality and specific market trends. Lab-grown diamonds, though high-quality, do not hold their value as strongly in the resale market. Since they are relatively new and can be reproduced in controlled environments, the demand for pre-owned lab-grown diamonds is currently lower.
Cost
Lab-grown diamonds typically cost 20-40% less than natural diamonds of similar size and quality, making them attractive for budget-conscious buyers.
Certifications and Detection
Both types of diamonds can be certified by reputable organizations, like the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). These labs use advanced equipment to detect whether a diamond is lab-grown or natural.
How Diamonds Are Evaluated: The 4 Cs
Diamonds, whether natural or lab-grown, are evaluated using the 4 Cs: Carat, Cut, Color and Clarity. These factors help determine a diamond’s quality and value.
Carat
Carat refers to the weight of a diamond. One carat equals 200 milligrams. Larger diamonds are rarer and more valuable, although carat weight is just one aspect of a diamond’s worth.
Cut
The cut reflects how well a diamond’s facets interact with light. Diamonds are often cut to maximize sparkle, with round brilliant cuts being the most popular and sought after for their light-reflecting properties.
Color
Diamonds are graded on a color scale from D (colorless) to Z (noticeable color). Colorless diamonds are generally more valuable, though some fancy-colored diamonds, such as pink or blue diamonds, can also command high prices.
Clarity
Clarity measures the presence of internal or external imperfections, known as inclusions and blemishes. Diamonds with fewer inclusions are rarer and more valuable.
Each diamond is unique, and jewelers or gemologists use these 4 Cs, along with grading reports from trusted labs, to provide an accurate assessment of quality and value.
Sell Your Diamond Jewelry
If you have diamond jewelry that no longer suits your style, or you simply want to upgrade, selling it can be a wise option. However, the resale process can be complex, especially for diamonds, as the market fluctuates. To ensure you receive a fair price, consider choosing a reputable buyer like National Rarities.
