Lab vs Natural Diamonds: 7 Amazing Shape Differences

1. Lab vs Natural Diamonds: What’s the Difference?

With the rise of lab-grown diamonds, many jewelry enthusiasts are left wondering about the real differences between these man-made gemstones and their natural counterparts. While both share the same physical, chemical, and optical properties, there are several key distinctions that set them apart. In this comprehensive guide, we’ll explore the seven amazing shape differences between lab and natural diamonds.

2. The Formation Process

• Natural diamonds are formed deep within the Earth’s mantle over billions of years under immense heat and pressure.
• Lab-grown diamonds, on the other hand, are created in highly controlled environments using advanced technological processes that mimic the conditions found in nature.

This difference in formation processes results in varying growth patterns and crystal structures, which can influence the overall shape and appearance of the diamonds.

3. Symmetry and Proportions

• Natural diamonds often exhibit slight imperfections in their symmetry and proportions due to the unpredictable conditions under which they are formed.
• Lab-grown diamonds, however, are meticulously crafted under precise conditions, resulting in a higher degree of symmetry and more consistent proportions.

These subtle differences can affect the way light interacts with the diamond, impacting its brilliance and sparkle.

4. Culet Size

• The culet, the small facet at the bottom of a diamond, is typically larger in natural diamonds due to the challenges of precise cutting and polishing.
• Lab-grown diamonds often feature smaller culets, as the controlled environment allows for more precise cutting and polishing techniques.

A larger culet can affect the diamond’s light performance, potentially reducing its brilliance and fire.

5. Girdle Thickness

• The girdle, the thin edge around the diamond’s circumference, is often thicker in natural diamonds due to the inherent variations in the rough diamond crystal.
• Lab-grown diamonds tend to have more consistent and thinner girdles, as the rough crystals can be more precisely cut and polished.

A thicker girdle can impact the diamond’s overall proportions and light performance, while a thinner girdle can enhance its brilliance and fire.

6. Inclusions and Blemishes

• Natural diamonds often contain inclusions (internal flaws) and blemishes (external imperfections) that are unique to each stone, resulting from the Earth’s natural formation process.
• Lab-grown diamonds can also exhibit inclusions and blemishes, but they are typically fewer and smaller due to the controlled environment in which they are grown.

These inclusions and blemishes can affect the diamond’s clarity, which is an important factor in determining its value and beauty.

7. Color Variations

• Natural diamonds can exhibit a wide range of color variations, from rare fancy colors to subtle tints, depending on the presence of trace elements and the conditions under which they were formed.
• Lab-grown diamonds, while available in various colors, often exhibit more consistent hues due to the controlled growth environment and deliberate introduction of certain elements.

Color is a crucial factor in determining a diamond’s rarity, value, and overall aesthetic appeal.

In conclusion, while lab-grown and natural diamonds share many similarities, the differences in their formation processes and growth environments result in distinct shape characteristics. Understanding these shape differences can help jewelers, gemologists, and enthusiasts appreciate the unique qualities of each type of diamond and make informed choices when selecting these precious gemstones.
