My Name is Ray and I have been collecting for a few years. I have studied machine made swirls for a long time. Cut my teeth on Alley Agate then did research on Jackson where I have at one time or another have owned aprox. 90% of the styles that they have made. I have been the owner of three of the Jackson bags. I am currently learning Christensen Swirls and hope to share some pictures with the forum in the future.
