Just like anything else created by nature, diamonds can have imperfections, or “flaws,” that may diminish their beauty. Whether you’ve inherited a diamond or purchased one, you may be wondering: Can a flawed diamond be fixed? Let’s take a deeper look at the nature of flaws in both lab-grown and natural diamonds and whether they can be corrected.
What Makes a Diamond Flawed?
Diamonds are graded on their clarity, which measures the presence of internal or external imperfections. These imperfections, known as inclusions and blemishes, can occur naturally during the diamond’s formation, whether deep within the Earth or in a lab. Inclusions are internal flaws such as air bubbles or other minerals trapped inside the diamond, while blemishes are external marks like scratches or chips on the surface.
The clarity of a diamond is one of the key factors in determining its value, along with the cut, color, and carat. Some of the most common types of inclusions include:
- Feather: Small cracks inside the diamond.
- Clouds: Tiny clusters of inclusions that look like clouds when viewed through a magnifying lens.
- Needles: Thin, needle-like inclusions made up of minerals.
- Graining: Irregularities in the diamond’s crystal structure that may create a wavy appearance.
The visibility of these imperfections depends on the size and location of the flaw. Diamonds with no visible inclusions are extremely rare and expensive, but diamonds with minor flaws can still be stunning and valuable when set in the right way.
Can Flaws Be Removed From Diamonds?
While the idea of “fixing” a flawed diamond sounds appealing, the process is much more complex than simply erasing imperfections. Once a diamond has formed, its internal structure and clarity are permanent. However, there are a few treatments available that can potentially improve its appearance or make flaws less noticeable.
- Laser Drilling: This process involves using a laser to remove internal inclusions, usually small black spots or mineral deposits. The laser creates a tiny hole that allows the inclusion to be removed or lightened, making it less visible.
- Laser Welding: Small chips or fractures on the surface of the diamond can sometimes be repaired through laser welding, which fills in the cracks with a special material that blends with the diamond’s surface.
- Re-cutting: If the diamond has significant external blemishes or an imperfect shape, it may be possible to have the diamond re-cut to improve its symmetry and minimize the flaws. This process, however, can also reduce the carat weight, so it’s not always an option.
- Treatment for External Blemishes: For minor scratches or blemishes on the surface, professional cleaning or polishing might help restore some of the diamond’s original shine. However, deeper blemishes will likely remain.
While some imperfections can be improved or minimized, most diamonds will retain their inherent flaws to some degree. Choosing a diamond with minor flaws that are less noticeable or strategically setting the diamond can be an alternative way to “fix” a flawed diamond aesthetically. If you own a diamond with noticeable flaws, it’s worth consulting a professional jeweler to determine whether it can be improved and to explore the best options for you.
