Gemstones have always been a fascination for humans. The stunning allure of these gems, combined with their rarity, make them prized possessions that are sold at prices that only the wealthy can afford.
Different Types of Gemstone Inclusions
Have you ever wondered how these beautiful gemstones are formed? Gemstones are formed naturally over millions of years, under the earth's surface. They are composed of minerals and other natural materials. When gemstones are formed, they sometimes contain inclusions.
An inclusion is a material trapped inside a gemstone that can be visible to the naked eye or only visible under a microscope. Inclusions can be air bubbles, minerals, liquids, or fractures. These inclusions give a unique character to each gemstone and are a natural indication of where and how they were formed.
There are different types of gemstone inclusions that one can come across. Let's take a look at some of them below:
1. Petroleum Inclusions in Quartz

These inclusions look like a black fingerprint or leaf inclusions in clear quartz. These inclusions are caused when petroleum gets trapped during the formation of the quartz crystal. The petroleum reacts with the minerals in the quartz and creates a dark inclusion. These inclusions are quite rare and can only be found in certain regions of the world.
2. Diamond Inclusions
