Item Description
Groutite is a RARE manganese oxide. Lustrous needles of groutite, to 4 mm, are RICHLY scatttered on BOTH sides of the ribbed, quartz-replaced petrified wood! I have seen just a few specimens of this material before, and in every case it sold immediately - this is rare, hard to obtain material. This specimen is from a remarkable and so far unique find in 1975. A miner who"d worked in the area for years brought in a small lot of specimens to a rock shop owned by Lolette Dalbeck in Ridgecrest, California. Ex Mullane Collection.
