Your Gemologist has a lot of information also

Tourmaline is green pink in shades "blue indicolite" red

Kyanite has a nice blue haze have a look at the links enjoy

Tourmaline is very abundant and has the best-developed crystals in pegmatites and in metamorphosed limestones in contact with granitic magmas. Because tourmaline is resistant to weathering, it accumulates in detrital deposits and is a common accessory mineral in sedimentary rocks. Gem-quality pegmatites are found in the United States (southern California and Maine), Brazil, and Madagascar.

In addition to its use as a gem, tourmaline is employed in pressure devices because of its piezoelectric properties—i.e., its ability to generate electric charge under mechanical stress or its change in shape when voltage is applied. It has been used in depth-sounding apparatus and other devices that detect and measure variations in pressure.

Coloured crystals of tourmaline are very strongly dichroic—i.e., they are of different colour when viewed in the direction of different axes; the ordinary ray is almost completely absorbed. Plates cut parallel to the vertical axis of a tourmaline crystal allow only the extraordinary ray through; if two such plates are placed in crossed position, the light is entirely blocked. A pair of these plates form a very simple polarizing apparatus known as tourmaline tongs.

if you want blue stones try getting a topaz maybe even a sapphire. there is also blue chalcedony, which is really pretty. i'm not sure if tourmaline comes in blue though sorry and good luck.

yes it does come in blue, it is called INDICOLITE. U get it on ebay, or go 2 a local mineral club or shop. good luck.
