It's not the most flowery topic, so let's get straight into the books on this one.
There are several types of inclusions found in gemstones, including:
Crystalline inclusions: These are small crystals that have grown inside the gemstone. They can be a different mineral than the main gemstone and can affect the transparency and colour of the stone.
Liquid inclusions: These are pockets of liquid trapped inside the gemstone. They can appear as bubbles or droplets and can also affect the transparency and colour of the stone.
Solid inclusions: These are bits of other minerals or rocks that have become trapped inside the gemstone. They can appear as small dots or lines and can affect the transparency and colour of the stone.
Healing fractures : These are fractures that have occurred within the gemstone and have been healed over time. They can appear as lines or feather like patterns.
Feathers: These are thin, wispy inclusions that resemble feathers. They are caused by stress fractures in the gemstone and can affect the durability and value of the stone.
Fingerprint inclusions: These are unique patterns of inclusions that resemble fingerprints, caused by the formation process of the gemstone.
Things To Consider;
Although inclusions can be an internal fault point and it is worth considering the durability of the stone, this is dependent on the type of inclusion and positioning.
A fracture close to the edge or surface, will be more susceptible to further fracturing and potentially cracking the surface. However, the likelihood of this happening will generally be at the production stage prior to receiving your ring, especially during an ultrasonic clean - which uses ultrasonic vibrating waves to remove compound from the piece. Therefore, the risk will largely lay with the jewellers.
The inclusions are generally more a representation of a brittle type of stone, which will risk cracking with or without the inclusions.
At Lei è we do love the individualistic characterisation that inclusions add to a stone. We see it as another unique defining element from the earths natural process.
She is, unique.
