What crystal is closest to the diamond?

Are you talking about crystals like amethyst? Or more like crystals you might find in a glass of water, like quartz?

crystals like amethyst

Does that mean you mean the amethyst you buy in jewelry stores, rather than the actual mineral, because that’s definitely not a crystal. But maybe you meant crystals like the rock that’s sold in jewelry stores, like an emerald?
