Sapphire ~

Small sapphire pebble
Sapphire is traditionally referred to as a 'precious' gemstone, as are diamond, ruby and emerald.  Along with ruby, it is a variety of the mineral corundum.  When we think of sapphire we think of deep blue, but in fact it comes in every colour except red, because if it's red we call it ruby!

The bright blue streak in the image of the pebble is a reflection.
