Insulator for sale is on the left. The one on the right is a 'standard' cobalt color. There is a noticeable difference in the darker, deeper cobalt, really an exceptional color that stands out when back lit or underlit. This will make a great addition to any color line up or to add the WOW factor in your display. Insulator has 5 open drips, a tiny slice that takes out one drip, and a larger skirt flake that takes out two drips. Otherwise the insulator is in excellent condition and displays very well from the front and back. I have really enjoyed this piece but I owe the tax man. Asking a flat $200 shipped anywhere in the U.S. First e-mail that says "I'll take it" gets it.
