                                                  TO CHOOSE 
                                                   
                                                  The main consideration
                                                  in choosing a red spinel is
                                                  finding a color that is close
                                                  to pure red. A highly saturated
                                                  red, even if somewhat light,
                                                  is an appealing color. Look
                                                  for beautiful color first,
                                                  instead of insisting on a dark
                                                  red color just because it is
                                                  a red spinel. Since mining
                                                  qualities are essentially limited,
                                                  it is important to search patiently
                                                  and select a pleasing pink
                                                  or red spinel with no violet
                                                  or brown tint. 
                                                   
                                                  Next, consider the quality
                                                  of the stone's overall appearance.
                                                  As long as the stone is not
                                                  excessively deep, or does not
                                                  shown a window (an area of
                                                  washed-out color seen when
                                                  the stone is viewed from above),
                                                  a certain degree of compromise
                                                  is necessary. The beauty of
                                                  the color's hue is by far the
                                                  most important point when choosing
                                                  a red spinel.
