Rocks, minerals, metals and gemstones have always played an important role in the lives of humans. Precious stones were being used for tools and decorative purposes, even before recorded history began.
See our Minerals Collection or our Specimens Page to purchase some of the rocks and minerals referred to below, but we do not offer a collection specifically with the below listed stones and gems.
While there are several grades of ulexite available on the market, Gold Bullion Corporate currently offer GRADE A (products) material because of its clarity. We have the best precious stones availlable and several units worldwide for testing.
