The hyalite opal from my mining claims in Utah exhibits a super strong fluorescence under both long and shortwave uv light 🤯 | Bigfoot Crystals

When it solidifies it creates an opalized replica of the original object. These are also known as ‘jelly mould’ fossils. In some rare cases, like shown above, we have found large and rare opal fossil specimens with beaut
