I wrote an article for Rock & Gem Magazine, August 2018, which you can check out here at the website, about yellow agates.

The article describes in detail that the number of yellow agates found on a very small portion of The Carver was a geological oddity.

Pictured here is one of The Carver yellow agates, handcrafted into a gemstone suitable for setting.

Yellow agates within the world and family of agates are quite uncommon and yellow agates in jewelry are even more rare.  Enjoy.
