What is a polymer in relation to gemology?

In gemology, a polymer refers to a durable liquid filling material that hardens. This substance is often used to enhance the appearance of gemstones by filling in fractures or enhancing color through a process known as "polymer treatment." The polymer is typically injected into the stone while in its liquid form, and upon exposure to certain conditions, it solidifies, providing the stone with improved clarity and overall aesthetics.

Polymers are particularly beneficial in the treatment of more fragile stones or those with natural flaws, as they can significantly improve the marketability and visual appeal without compromising the integrity of the gemstone itself. This technique is widely accepted in the industry, as it allows for greater accessibility to beautiful stones that may not have been viable for sale in their untreated state. Understanding the role of polymers in gemology is crucial for evaluating the quality and treatment of gemstones.
