One (juicy) idea at a time.  Are you into bluberries or raspberries? 

Sapphire and ruby are different shades of the same mineral, called corundum. Technically, all corundum variations are called sapphires - that's why sapphires come in so many different colors. But bright deep juicy raspberry pink sapphires are more rare, and they are referred to as rubies.
 
Corundum crystals are very durable, they rank #9 in hardness on Moh's scale (diamond is the only stone that's harder), making them excellent choice for rings.
