OPAL/ TOURMALINE
Opal
Opals are an opaque, colorful stone that is found mostly in Australia.  They are made up of a collection of silica spheres, which diffract light and create its multi-color effect.
Opals come in a vast array of colors and types.
MYTH:
Opals represent hope, purity, and innocence.  They are believed to heal poor eyesight and banish evil spirits.  Opals are thought to bring good fortune, especially when worn by children.
White Opal
White (or Milky) opal is the most common type of this gem.  It has a light or pale background and often displays red, green and blue refracted light.
Black Opal
Black Opal is considered the most valuable of Opals.  It has a dark background colour when viewed from above.
Boulder Opal
Boulder opal is a solid stone that consists of a fine layer of natural opal which has formed naturally on ironstone rock.  Boulder opal from Queensland is declared by many experts to have the most brightness and best appearance of the Australian opals. 
Crystal Opal
Crystal opal is transparent or extremely translucent and contains the entire spectrum of colors.  A crystal opal is transparent,and a black backing is often placed behind the Opal to allow the bright natural colours of the Opal to appear.
Fire Opal
Fire opal is bright orange in color.  It can vary from completely translucent without any opalescence or iridescence, to semi-translucent with very noticeable flashes of iridescent color.
It is often called Mexican fire opal, as Mexico is one of its prime sources
.
Tourmaline is a bright and magnificent gemstone that can be found in just about any color. Its name comes from the Sinhalese word 'turmali,' which means 'mixed. Tourmaline has a hardness of 7 to 7 1/2, so it can withstand years of wear.

Tourmaline is a great gemstone because it is so versatile.  In addition to the rainbow of colors that they come in, they can also be bi-colored or even tri-colored!  The most fascinating of the different types may be the watermelon tourmaline, named for its remarkable resemblance to a watermelon  (as seen above).
MYTH:
Tourmalines promote good health and harmony. It is also said to develop social popularity.
When a tourmaline is heated, compressed or vibrated, it will create a different electrical charge at both ends of the crystal. On the other hand, if you apply an electrical charge to it, it will begin to vibrate.
Chrome tourmalines are wildy popular for their vivid green hue.  It gets its coloration from chromium, which is the same compound found in emeralds.
