Inclusions: The internal wonders of gemstones!
Thanks to the books and the different writings from Professor Edward Gubelin, also known as the "father of modern gemology", we have discovered during our gemological studies the "internal world of gemstones" and have learned to appreciate it. For years, inclusions in gemstones have been seen as imperfections or flaws. Now with microscopes more readily available and affordable, and pocket field-gemological tools such as "dark-field loupes", the internal world of gemstones can be appreciated by almost anyone.
Inclusions are extremely precious to the gemologist as more synthetics and treated stones are present in the market everyday. Learning to recognize these inclusions is essential knowledge for the gemstone buyer as he will be better able to separate the fine natural gems from material that is the result of human expertise in crystal growing or heat treatment.
Inclusions can also tell you indications about the geologic origin of the stone. For example, metamorphic rubies from Mogok and their igneous cousins from Thailand or Africa differ a lot when we study their internal world. So some small tell-tale inclusions that don't disturb the general beauty of the stone with the naked eye can no longer be called flaws. They can tell you the story of the gemstone formation: They are the natural trademark of the stone! The proof of its natural, synthetic or treated status.
Furthermore, some inclusions are just beautiful in themselves: Golden needles in high luster topaz, insects trapped in Amber, fine liquids of incredible complexity in sapphire, crystals looking like star ships in rubies, cavities with liquids and gas bubbles in quartz, or sapphires, and how can we not mention the incredible diversity of crystals found in quartz?
Inclusions are definitively no longer considered blemishes that lower the value of gemstones. They are precious and beautiful wonders that unquestionably add value to them!
Gemologists classify inclusions in 3 groups:
Protogenetic: Which were formed before the gemstone host, they are always mineralistic, typically crystals more or less corroded.
Singenetic: That formed at the same time as the host crystal. They were imprisoned inside it during its formation or have appeared during its cooling as rutile needles in rubies.
and Epigenetic: Formed after the gem was grown. Typical from this type are limonite, iron staining or oil that can fill the natural fissures of the gemstones.
The recognition and the understanding of these inclusions is a key skill to learn for all gemologists or gemstone buyers who want to know which stones they are dealing with.
