Pecos Diamonds Quartz Crystals, also known as Pecos Valley Diamonds, are double terminated and cluster quartz crystals that form along the Pecos River in southeastern New Mexico. This area includes Artesia and Roswell, New Mexico. The outcrop area spans an area 100 miles long by as much as 25 miles wide along the margins of the Pecos River valley. Pecos Diamonds are unique for their size, variable color, and crystal morphology. Many times you will find gypsum lines or boulders that still contain Pecos Diamonds in matrix from when they were formed. You will also find Selenite quarries among the Pecos Diamonds.
