On May 20th , 20 CCGMS Members joined CCGMS Field Trip Leader Rocky Collins to dig for staurolite in Mineral Bluff, Georgia. The breeze and overcast clouds kept us cool most of the day on the hillside of the Burkhalter Ranch. Staurolite crystals are fascinating minerals known for their unique cross-shaped formations, which have earned them the nickname “fairy stones” or “cross stones.” These crystals are typically found in metamorphic rocks, particularly schist and gneiss formations, across various regions worldwide. Staurolite crystals are composed of aluminum, iron, and silicon. They form as a result of the metamorphic process, where high temperatures and pressures cause minerals to re-crystallize and rearrange their atomic structures. In terms of appearance, staurolite crystals are typically brown or reddish-brown in color, with a resinous to vitreous luster. These captivating crystals are treasured by collectors, crystal enthusiasts, and those seeking a deeper connection with nature and the Earth’s geological wonders.
Jerry & Brianne Johnson found some Maltese Crosses, a specific type of staurolite where the intersecting crystals meet at 90°. The property owner thankfully used their backhoe to dig out some freshly exposed (and deeper) dirt… then we really started finding a lot more staurolite crystals.
