If you search what is popularly referred-to as "boulder (or "ribbon") turquoise, it will become apparent that there is a lot of difference in this type of stone. Look at the third pic in this post to see how the look is derived—and why it is so much more expensive. Lots of waste in ferreting-out the little ribbon of turquoise out of the rock. The ribbons of turquoise in both of these earrings runs horizontal instead of vertical, and the differing shades of agate the turquoise courses through has varying highlights. The Drifter hand-picks all of these ribbon earring offerings. In this case, each earring weighs .20-ounces and is about an inch and 1/8th-long and .75-inches wide. Hallmarked "ELOUISE KEE."
