White Quartz arrowhead from creekbed in north georgia

This is a nice quartz arrowhead that I found in a creekbed in north georgia on my friend's property about 15 years ago. I have not studied up on the native americans of this region in a long time, but I do remember that arrowheads were rarely ever made from quartz.
I probably won't be able to answer many questions about this item, except for details on how big it is, length, etc... Happy bidding!
