Spinel is a colored stone that's all about the color. The reds, oranges, flame reds, orange reds, pinks, purples, cobalt blues--all of these colors are best of breed in spine. The colors don't get any better than these in any other gem species. In fact, the best spinel in any color beats the best color in any other gem species. Color, color, color! In real estate, it's 'location, location, location'. In colored gems, it's color, color, color.
