Clear white and icicle shaped, the gem is the fifth largest diamond found by a park visitor since the state park was established at Arkansas's diamond site in 1972. 

Bobbie Oskarson of Longmont, Colorado, found the diamond on June 24 in a couple of scoops she had dug from a small mound of dirt. 

Oskarson was in the southwest corner of the park's over 37-acre search field in an area known as the Pig Pen, aptly named because it is the muddiest part of the search area after a good rain. 

At first she thought it might be a quartz crystal due to its elongated shape, but park staff later confirmed that she had found a diamond.
