Learn About Jewelry

At Colonial Jewelers we believe in the power of education. All our team members are fully trained in all aspects of jewelry education. We learn about how different gems are graded, where they originate and how they have been valued historically.


At Colonial Jewelers, we pride ourselves in only selecting well-cut gemstones in the finest hues and tones. You can learn more about Gems, both their scientific characteristics and their history and legends here.
