This was made in the 80's with we started experimenting with new materials, This is a well-made ring with a Center Stone CZ and lab-created blue opal. It is well made and needs a little cleaning which I did after I took the pictures. It weighs 5.73. It is an unusual and fun ring to wear. It will come with a velvet bag and gift box. Ready to give to that special person. For you from the High Plains of Kansas!
