Overall good value for the money. Definitely some real crystals such as unakite, tiger's eye, rhodochrosite, and tourmalated quartz. However, the turquoise is more than likely dyed howlite. There are some that appear to be dyed glass rather than authentic crystal. For example, the purple pieces that represent amethyst are definitely not genuine amethyst. More than likely they are glass dyed purple.Overall, even with the glass pieces, this was a good value and is good for jewelry-making and decorSee full review
