What causes abrasions in gemstones?

Abrasions in gemstones are primarily caused by tiny nicks and pits that develop due to wear and damage on a gem's facet edges or culet. As gemstones are worn over time, they may come into contact with various surfaces, resulting in microscopic scratches or surface degradation. This can happen through everyday activities, such as wearing jewelry during physical activities or even just through regular handling. The facets of a gemstone are particularly susceptible to this kind of wear because they are the parts of the stone that make contact with other surfaces, which can lead to these unwanted marks.

Understanding this facet of gemstone care is crucial for maintaining their appearance and value. Regular inspection and appropriate storage can help mitigate the risk of such abrasions.
