An Intro to Gemstone Treatments and Enhancements

In order to maximize their appearance and wearability, gemstones are often enhanced with treatments based on the stone type and the desired effect. Due to the rarity and uniqueness of colored gemstones, most fine jewelers (including Blue Nile) enhance their gems using various techniques. Some of these procedures have been around for centuries, while others have been developed in recent years.

What are Enhancements?

There are many methods used to enhance a gemstone’s color, clarity and durability and maximize its beauty. Different gemstones are enhanced differently, depending on the type of gem and the end goal.
