Well I read about these gems in book about minerals and I found out that the choise of them wasn't accidental. Rutile crystals are commonly twinned. Defects in the crystal ctructure in corundum cause the padparadscha colour. Rhodonite I think, could br chosen because pearls are servants and rubies are common soldiers. I'm not sure about Fluorite. Maybe because it's so colourful and there are often many crystals together.
