Carroll Chatham’s first blue sapphire was grown in 1975. His original production grew from the seed crystal of a Ceylon sapphire, known for their magnificent hue. 

 

Blue sapphire is the most difficult gem crystal that Chatham grows. Color in sapphire often follows the crystal structure in color zones. Even the best sapphire crystal has different shades of blue in it. That’s why Chatham lab-grown sapphires come in three lovely shades of blue, not just one.

 

Chatham lab-grown blue sapphire is one of Chatham's bestselling colors. Maybe that's because blue is America's favorite color, making it a popular choice for those seeking high-quality and responsibly sourced gemstones.
