Natural El Dorado sapphire paydirt from Helena, Montana. This gravel is not mine-run, nothing has been washed out of the material, only the large rocks screened out. Pulled from the pay-layer, this paydirt runs rich in Montana sapphire with a chance at a gold flake or two! This "lottery ticket" packaged in a rustic wood box should put a smile on the face of the treasure-hunter in your life. Keep the sturdy wooden box to house your mining tools or other treasures afterwards.
