What is a natural inclusion?
A natural inclusion is an internal characteristic trapped within a gemstone during its geological growth.
What do these markings reveal about the stone's identity?
In gemology, inclusions are often considered the fingerprints of gemstones. They are tangible proof that the material has been shaped by nature over millions of years, unlike a glass or plastic imitation which would often be too perfect or have characteristic round air bubbles.
You might think that lab-grown stones escape these inclusions. Contrary to popular belief, these stones also have them, inherited during the technological manufacturing process.
What inclusions can weaken a piece of jewelry?
Some inclusions have a greater influence on durability, especially when they reach the surface or create areas of tension.
- Fissures near the edges: These fissures weaken the stone and make it more susceptible to impact.
- Catchy cavities: These inclusions require special attention to avoid dirt and shocks.
- Dense needles or crystals in the center: These imperfections can cloud the stone's transparency.
For a piece of jewelry worn daily, such as engagement rings, a protective setting and precise mounting are essential. If you opt for a custom design, we recommend making an appointment with our jewelers, who can adapt the design to your lifestyle.
Frequently Asked Questions about Natural Inclusions
It is impossible to remove an inclusion located at the heart of a stone without re-cutting it. Some laser treatments can visually reduce black inclusions in diamonds, but this alters the gem's natural structure.
Internal solid or liquid inclusions do not move over time. However, if a stone has an open fracture reaching the surface, a violent shock could enlarge this existing fault, hence the importance of a protective setting.
Gemologists use a 10x magnifying loupe or a binocular microscope to observe internal details. It is at this level of magnification that the official clarity grade of a diamond or gemstone is determined.
