This is one of the finest Columbia River Gem Points known to exist. It may be the finest Gunther Barbed/Rogue River ever found. It is the largest example I have ever seen. It is a huge 2 3/4" long. It is made from the finest quality translucent moonstone white agate. It has beautiful patina. The tip and barbs are perfect, not even a spider bite anywhere on the piece. It is a G-10+. It was made by a master knapper. I purchased it in 1988. I have full provenance that goes to the buyer. I was told it was given to the mayor of Klamath Falls by the citizens upon his retirement and purchased from his estate. It comes with a Bill Breckinridge COA using Laser Spectrographic and microscopic evaluation, visible spectrum florescence and UV examination. This is the best of the best and the rarest of the rare.
