Agate has been used for over 3000 years and examples can be found from ancient times to the forming of America. These were a perfect size for arrowheads when hunting small to medium size game and today make interesting jewelry. This set of six will vary in size from 1- 3/4" to approximately 2-1/4" long and all sizes in between. These are modern, handmade agate heads. Due to the hand carving process and natural occurring variance in the stone, no two will ever be alike.
