Murfreesboro (Pike County) was incorporated. It is the county seat of Pike County, which lies in the southwest corner of Arkansas and is an area of tremendous geological diversity. In addition to diamonds, other gems and minerals such as amethyst, quartz, garnet, jasper, calcite, barite, lamproite, and banded agate are found in the area. The discovery of diamonds is celebrated every June with the Diamond Festival. The Crater of Diamonds State Park sponsors a gem and mineral show and John Huddleston Day, honoring the man who discovered the first diamonds in the area.
